The Missouri
and Yellowstone Rivers In North Dakota ( Williston Reach)
- A Report to the
Director, 2002
BACKGROUND
The Missouri River of the 1800's has been inalterably
changed as a result of numerous channelization and impoundment
projects (six main stem dams were constructed beginning
in the 1930s). What was once a turbid, warm, and dynamic
river has been transformed and segmented into six large
storage reservoirs, more than 700 miles of rock lined
channel, and five smaller reaches of unchannelized river
with highly regulated flows. Dam construction and channelization
have collectively and dramatically modified fish and wildlife
habitat throughout the entire Missouri River. Main-stem
dams have eliminated migrational movements of fish, modified
the hydro cycle, changed the depositional nature of sediment
carried by the Missouri River and its tributaries, all
but eliminated the periodic inundation of the flood plain,
transformed the configuration of the river channel and
associated backwaters, and caused colder summer water
temperatures.
Of the approximately 350 miles of the Missouri River System
(MRS) in North Dakota, there are roughly 50 miles of the
Yellowstone and Missouri rivers above Williston that remain
semi-natural in terms of form and function. This area,
termed the Williston Reach, is truly unparalleled not
only in North Dakota but throughout the Missouri River
Basin, due primarily to the influences of the Yellowstone
River.

FIGURE 1.
The final 18 miles of the 678 miles of the Yellowstone
River lies within North Dakota. It joins with the Missouri
River at river mile 1581 and above the confluence of these
two rivers, the Missouri extends only about 5 miles upstream
before it meets the Montana border (see Figure
1). Downstream from the confluence, the Missouri River
is free-flowing until it encounters the headwaters of
Lake Sakakawea. Depending upon Lake Sakakawea's elevation,
the length of this free-flowing stretch may be as little
as 15 miles (e.g. 1997) to as many as 50 miles (e.g. 1991).
A tremendous amount of sediment has accumulated in the
headwaters of Lake Sakakawea (estimated annual deposit
rate of 26,000 acre-feet annually). This sediment has
buried the old river channel downstream of river mile
1535 (approximately). Lower elevations in Lake Sakakawea
does not provide additional riverine habitat but rather
exposes vast expanses of accumulated sediments. The Little
Muddy River, which enters the Missouri River from the
north just east of Williston, is the only significant
tributary of either the Missouri or Yellowstone rivers
within the Williston Reach.
The Missouri River above Lake Sakakawea is unique to the
entire MRS because it exhibits characteristics of two
very dissimilar rivers. The Yellowstone River is basically
unregulated, with no main stem impoundments, and thus
exhibits natural, seasonally high flows of turbid water.
However, a few tributary impoundments do have an influence
on the Yellowstone's flow. For example, Yellowtail Reservoir
on the Bighorn River (a significant tributary to the Yellowstone
River in Montana), impounds nearly a million acre-feet
of water and limits the natural, high discharges of the
Bighorn into the Yellowstone during snow-melt periods.
The average annual flow of the Yellowstone River at its
lowest gauge station (at Sidney, Montana) is 12,250 cubic
feet per second, with a maximum instantaneous flow estimated
at 159,000 cfs in June 1921. Due to upstream water depletion
projects, flows in the Yellowstone River have declined
by approximately 24% from historical levels. Contrary
to the Yellowstone River, the flows of the Missouri River
upstream of the confluence are highly regulated (mostly
by Ft. Peck Dam, approximately 200 river miles above the
confluence), with summer flows relatively clear and cool.
Since closure of Ft. Peck Dam in 1937, annual flows of
the Missouri River at its lowest gauge station above the
confluence with the Yellowstone River (at Culbertson,
Montana) have averaged 10,270 cfs. The peak post-impoundment
flow for this reach of 78,200 cfs occurred in March 1943.
Due to the meandering nature of both rivers and the fact
that the Yellowstone remains unregulated and flows northeasterly,
occasional but significant ice-jams occur in this reach.
For example, gauge readings during a March 1994 ice-jam
in the confluence area produced a flood stage equivalent
to flows well in excess of 100,000 cfs. In fact, several
of the highest stages ever recorded were caused by ice
jams and not necessarily high discharges.
Because the Williston Reach of the Missouri River retains
many of the components of a natural river, the fish species
assemblage is both unique and very important. Species
typical of turbid riverine conditions such as paddlefish,
sauger, big mouth and smallmouth buffalo, shovelnose sturgeon,
and channel catfish, are abundant and naturally sustained.
Walleye and northern pike which thrive in downstream Lake
Sakakawea are also seasonally common and support very
popular sport fisheries during periods of the year (i.e.
when the water is relatively clear). Most of the 41 fish
species that have been documented in this reach are generalists
and are found across a wide range of habitat and geography.
However, several species that require particular and increasingly
limited habitat can also be found in the Williston Reach.
For example, this reach represents one of the last strongholds
for pallid sturgeon (federally endangered), and sicklefin
and sturgeon chubs (both considered endangered on the
American Fisheries Society Dakota Chapter list). In addition,
the Williston Reach of the Missouri River supports one
of the most viable populations of paddlefish anywhere
within the species range. The critical importance of this
reach to several fish species of national predominance,
as well as its significance to other federally listed
and important wildlife species, indicates that this reach
is the most significant aquatic habitat in North Dakota.
The US Army Corps of Engineers (Corps) purchased the entire
lake bed and shoreline of Lake Sakakawea prior to its
impoundment. The acquisition boundary for this reservoir
included a substantial portion (approximately 25 river
miles) of the Missouri River upstream of Lake Sakakawea.
This headwater stretch is occasionally impacted by very
high lake levels. The shoreline and much of the floodplain
within this Reach, which generally extends from the area
near the mouth of the Little Muddy River (RM 1547) upstream
to the Erickson Island area (RM 1574), is almost entirely
publicly owned land. Most of this land is managed for
fish and wildlife purposes by the North Dakota Game and
Fish Department (NDGFD) as the Lewis and Clark, and Trenton
Wildlife Management Areas. Public ownership and management
have established a substantial riparian corridor of willows
and cottonwoods, which in turn benefit wildlife species
such as beaver, white-tail deer, pheasants and bald eagles.
The multitude of islands and sandbars of varying elevation
throughout the Williston Reach also provide breeding habitat
for Canada geese and federally threatened and endangered
least terns and piping plovers.
Another unique aspect of the Williston Reach is its' remoteness
caused in large part by the relative lack of boating access
sites and boat traffic. There are only three boat ramps
on the Missouri and Yellowstone Rivers upstream of the
headwaters of Lake Sakakawea. In fact, there are no boat
ramps on the Missouri in nearly 30 miles between the Highway
85 boating access site (RM 1552) and the confluence boating
access area (RM 1581). As a result, the entire middle
portion of the Williston Reach receives only limited,
seasonal boat usage.
The reality of the Williston Reach is that most of the
land use on privately owned property along the river and
throughout much of the active floodplain consists of high-intensity
agricultural use, primarily irrigated sugar beets. Oil
development is concentrated along much of the reach (even
on public lands), thus oil wells, pipelines and oilfield
traffic are commonplace. Irrigation project return flow
ditches serve as conduits for the delivery of agricultural
fertilizers and contaminants (i.e. herbicides and pesticides)
and potential avenues for allowing oil spills to directly
enter and contaminate the Missouri and/or Yellowstone
rivers. Any such spill has the capability of greatly impacting
the aquatic ecosystem. High land values coupled with valuable
subsurface minerals complicate potential alternatives
for protecting the Williston Reach from further habitat
degradation.
NEED
Although the MRS has become a highly segmented
ecosystem, each reach from Ft. Peck to St. Louis may have
direct or indirect impacts on the others. This is very
apparent in the Williston Reach, where the Yellowstone
and Missouri rivers above their confluence are so dissimilar,
yet the Missouri River below the confluence still maintains
many of the same functions as it did before the system
was greatly modified. Since approximately one-half of
the flows of the Missouri River below the confluence are
controlled by Ft. Peck Dam, balancing the riverine habitat
needs and demands requires a holistic approach toward
management and protection. Management actions need to
consider both upstream and downstream ramifications, and
specific needs for each reach.
In order to best meet the needs of the various river users,
while still protecting the valued fish, wildlife and associated
habitat of the Williston Reach, an objective assessment
of management possibilities needs to be conducted. This
includes the development and implementation of a resource
conservation plan. Public expectations need to be appropriately
framed within the context of physical reality. Well-intentioned
but unrealistic desires to manage the river for a set
of conditions which cannot be economically or ecologically
justified must be identified and avoided. Any plan should
be driven by unbiased hydrological and biological data
complemented with sound public education. In the end,
the goal for the Corps, North Dakota, and other states,
should focus on sustaining a healthy river environment.
CHARACTERISTICS
The characteristics of the Williston Reach necessary
to maintain and improve the form and function of the river,
including the current fishery and aesthetic components,
include:
- A braided channel in at least 25% percent of the
river.
- A dynamic channel that is allowed to move laterally,
through erosion and accretion, rather than vertically.
Channel degradation typically is a cumulative result
of bank stabilization, channelization and upstream
impoundment.
- Maintenance of the current magnitude, seasonality
and other components of the hydrology of the Yellowstone
River.
- Restoration of a more natural, pre-impoundment hydrology
(including temperature regime) for the Missouri River
below Fort Peck Dam.
- Maintain tributary magnitude and duration of discharge
which allow for unrestricted fish passage.
- Protection and restoration of flood plain woodlands,
backwaters and associated wetlands which sustain the
river's values.
- Land management activities which minimize pollution/pesticide
inputs.
ISSUES and RECOMMENDATIONS
This section identifies issues of importance and
recommendations within the Williston Reach.
- Fish Management
Fisheries management actions for this reach include
regulations, access, stocking, water management (i.e.,
flow regimes), and habitat protection/enhancement.
The current recreational fishery within the Williston
Reach is highly seasonal. Paddlefish, sauger, walleye,
northern pike, channel catfish and burbot are important
constituents of this fishery, especially from late
summer through spring which are clearer water periods.
Several other fish species, although not recreationally
important, are of national significance. Habitat within
the Williston Reach is critically important for the
pallid sturgeon, North Dakota's only federally listed
endangered fish species, as well as the sicklefin
and sturgeon chubs (two species that nearly warranted
federal listing). These three species of fish, along
with other unique species such as flathead chub, blue
sucker, shovelnose sturgeon and paddlefish, constitute
a truly remarkable assemblage of increasingly rare
species. The Williston Reach likely supports the largest
composite population of these fish species anywhere.
Presently, there are two fish management plans that
loosely guide management, protection and restoration
of several of these species. The Pallid Sturgeon Recovery
Plan, along with efforts of the Upper Basin Pallid
Sturgeon Work Group, have established and prioritized
work activities needed to restore the pallid sturgeon.
The inter jurisdictional Paddlefish Management Plan,
which deals with various components of paddlefish
harvest regulation, conservation and habitat management,
has been developed and implemented by the states of
North Dakota and Montana.
In addition to the issues listed in the aforementioned
management plans, success for fish management within
the Williston Reach is dependent on providing and
maintaining adequate habitat (with specific recommendations
as outlined elsewhere within this document). Also,
as boat usage within this Reach continues to intensify,
it may reach a level where it negatively impacts the
areas natural resources (i.e. collisions with paddlefish).
If so, specific horsepower, speed regulations and/or
closures should be adopted to alleviate these impacts.
- Flow Regime
The importance of the Williston Reach to the entire
MRS is founded in the continued maintenance of healthy
populations of its rarer, native fish species. The
fate of these rare species within the Williston Reach
is directly related to the quality and quantity of
habitat and maintenance of the historic hydrograph.
For Yellowstone River - Maintain the current hydrology
of the Yellowstone River
including magnitude, duration and seasonality of flows.
For Fort Peck releases (Missouri River) - The present
release pattern from Fort Peck
Dam generally includes relatively low releases in
spring and early summer and higher releases in mid
to late summer, fall and winter (compared to historic
flows). This release pattern is implemented primarily
to benefit downstream flood control and hydropower
interests which are generally very detrimental to
fishery needs.
A change in the release pattern from Ft. Peck, specifically
to benefit fish and wildlife resource needs, has been
recommended by the Missouri River Natural Resources
Committee (representatives of the Missouri River basin
game and fish agencies) and several others entities.
This recommendation, which is yet to be implemented
and evaluated, was developed with NDGFD input. The
following is a description of that recommendation.
Initiate increased flows from the dam for a 30-day
period when the lake surface water temperature reaches
18 degrees C. Powerhouse and spillway releases shall
be adjusted to attain a target river temperature of
18 degrees C at the Wolf Point, Montana gage. Depending
upon the water year, releases from Fort Peck Dam would
be as follows:
- For an upper Quartile runoff year: adjust dam and
spillway releases to achieve an average flow of 24,000
cfs at the Wolf Point, Montana United States Geological
Survey stream gage with a one-day peak flow of 38,000
cfs attained during the second week of the 30-day
period. During projected upper decile runoff years,
the proposed 38,000 cfs one-day release from Ft. Peck
would be reduced if the Yellowstone River flow (Sidney
gauge) is more than 60,000 cfs. Likewise, the proposed
24,000 cfs 30-day release from Ft. Peck would be reduced
until the Yellowstone flow dropped below 70,000 cfs.
This is based on the desire not to surpass the mid-June
1997 inflow (from the two rivers) into Lake Sakakawea
of approximately 100,000 cfs.
- For a lower Quartile-Upper Quartile runoff year:
adjust dam releases to achieve an average flow of
18,000 cfs at the Wolf Point, Montana stream gage
with a one-day peak flow of 27,500 cfs attained during
the second week of the 30-day period.
- For a below Lower Quartile runoff year: adjust dam
releases to achieve a target flow of 11,500 cfs at
the Wolf Point, Montana stream gage between May 11
and June 30. This flow is necessary to maintain suitable
spawning and incubation habitat for sauger and other
native fish species.
The remainder of the year a flow of at least 7,000
cfs should be provided at the Wolf Point gage for
maintenance of riffles and fish rearing pools. In
addition, powerhouse and spillway releases must be
adjusted through August 20 to ensure suitable water
temperatures (at least 18 degrees C at the Wolf Point,
Montana gage) for development and survival of native
riverine fish eggs, fry, and juveniles. Preliminary
data collected by the Montana Fish, Wildlife, and
Parks Department indicate that at least 25 % of the
discharge should be through the spillway to attain
suitable downstream water temperatures.
* NOTE: as of 2001, the Corps was continuing work
on NEPA requirements in order to move forward with
modifying Ft. Peck releases. This included implementing
and funding a biological monitoring program with data
collection beginning in the summer of 2001. Ft Peck
release modifications were also included in the USFWS
Biological Opinion for Missouri River endangered species.
- Endangered Species
Four federally listed species are present in the Williston
Reach: piping plover, least tern, bald eagle, and
pallid sturgeon. The plover, tern, and sturgeon recovery
plans include efforts and/or objectives within the
Williston Reach. Several other species have been petitioned
and/or evaluated for listing. The management recommendations,
as identified within the respective recovery plans,
should be implemented in order to prevent the listing
of additional species and to aid the recovery of listed
species.
- Bank Stabilization/Shoreline
Management
Most of the aquatic habitat in the Williston Reach
is continually being rearranged by an active river
channel that scours riverbanks and creates a maze
of sandbars. River meandering, including both erosion
and accretion, is a natural process that is vital
to both the creation and maintenance of a healthy
river ecosystem. Unfortunately, the purpose of bank
stabilization is to reduce lateral erosion, which
will ultimately result in riverbed degradation in
some areas. If the river can't maintain its sediment
load via bank erosion, it will take sediment from
the river bottom.
Approximately 9% of the Williston Reach has been directly
affected by revetments, jetties, riprap, car bodies,
tires, sheet/wood pilings, or channelization (this
estimate includes the impacts to nearly four miles
of meandering river around what is now Erickson Island,
where the river was straightened by the Corps). For
comparative purposes, approximately 30% of the Garrison
Reach of the Missouri below Garrison Dam has been
directly stabilized.
The vast majority of the perceived need to complete
additional bank stabilization projects within this
reach stems from the highly intense agricultural use
of the floodplain. This is especially true at many
locations where crops are planted right up to the
edge of the river. There is a great need to protect
the riparian corridor along much of the private portions
of the Williston Reach from additional bank stabilization
efforts. Programs to obtain conservation easements
and riparian areas in fee title should be developed,
funded and implemented to help alleviate the demand
for additional bank stabilization. In the event that
significant impacts caused by erosion to private lands
are documented, sloughing or conservation easements
(as identified by the Corps as the most prudent alternative)
should be obtained from the affected landowners, in
lieu of bank stabilization. In addition to being far
more environmentally friendly, sloughing easements,
conservation easements, and fee title acquisition
tend to be more economically feasible alternatives
than riprapping. The Corps estimated that the cost
to complete traditional bank stabilization was approximately
$600,000 to $1 million dollars per mile. As an example,
in 1996 the Corps stabilized approximately 4,000 lineal
feet of the Williston Reach using so-called >environmentally-friendly'
bank stabilization techniques. The cost of this effort
was about $450,000, or $113 per lineal foot (not including
an estimated $8,000 annual maintenance cost). By comparison,
the cost of purchasing the bank in fee title or acquiring
a sloughing easement on the adjacent land was evaluated
at $69,000, or only $17 per lineal foot.
Even though approximately 40% of the shoreline and
adjoining lands of the Williston Reach of the Missouri
and Yellowstone rivers are in public ownership, bank
stabilization efforts continue to be recommended in
order to protect select infrastructure, regardless
of land ownership. The purpose and need for any additional
bank stabilization should be critically evaluated,
and only under extreme circumstances should any additional
rip-rapping or bank stabilization be allowed. At the
very least, no additional public funds should be spent
if the sole intent of the project is to protect adjoining
private property interests.
- Sovereign Lands
Sovereign lands are those areas, including the bed
and islands, lying within the ordinary high watermark
of navigable lakes and streams within North Dakota.
The Yellowstone and Missouri rivers are considered
navigable. Generally speaking, the public has a right
to use sovereign lands for nondestructive, recreational
purposes (in some rare instances, the state may prohibit
the public's use of these lands for just causes).
A substantial portion of the sovereign land near the
Confluence provides good fish and wildlife habitat
and offers excellent recreational opportunities. However,
the public's use and access to many of these areas
is becoming increasingly restricted due to confrontations
with riparian landowners.
Currently there is a dispute among some riparian landowners
and recreational users over the location or existence
of sovereign land in the Confluence area. Because
of the dynamic nature of the Yellowstone and Missouri
rivers, the bed and islands within a particular reach
may change considerably in a short time. These changes
make it difficult to clearly identify the ordinary
high water mark used to define or establish sovereign
land. As a result, some adjoining landowners are claiming
riparian ownership (private) and restricting access
and use over what recreational users contend is sovereign
land.
The Department is currently working with the State
Engineer's office to develop a process that will assist
in the identification of sovereign land in the Williston
Reach. This process should identify and confirm the
public's right of ingress and egress to a sizeable
area of additional public land for fishing, hunting
and other recreational uses. In addition, it should
reduce modification/alteration (e.g. bank stabilization)
of public lands.
- Oil / Gas Development
A considerable amount of oil and gas development/activity
has been conducted in this Reach. More than 20 wells
and numerous pipelines are within the active floodplain,
and on occasion are completely submerged during periods
of high river flows and/or high lake levels. Although
several fairly minor oil spills have occurred in recent
years, no major spills have yet impacted this reach.
However, a major spill within this reach has the potential
to cause severe negative impacts. Most of the oil
field companies have oil spill contingency plans.
Many of these same companies have purchased some of
the needed equipment and supplies and have had their
employees complete mock oil spillway cleanup activities.
The US Fish and Wildlife Service developed an oil
spill contingency plan in response to a spill on the
west side of Erickson Island in the mid 1990's. This
plan contains a detailed listing of all oil wells,
pipeline locations, and detailed information regarding
the proper reporting and cleanup of any spill which
might occur in the future.
- Floodplain Management
The floodplain adjacent to the Williston Reach has
not experienced significant commercial or residential
development and associated impacts. In order to adequately
protect the river ecosystem within this reach, no
additional development on any of the publicly owned
floodplain should occur, and there should be limited
development on all privately owned property immediately
adjacent to the shoreline. As mentioned earlier clear
delineation of sovereign lands will help reduce resource
impacts, including all of the shoreline and associated
habitats below the ordinary high water mark.
Agricultural activities have cleared most of the floodplain's
natural vegetation to allow for the production of
high value crops. Existing agricultural practices
within the
floodplain often employ the use of flood irrigation
and the application of large quantities
of fertilizers and pesticides. For example, water
depletion (for agricultural uses) of the Yellowstone
and Missouri rivers continues and has significant
impacts on aquatic resources during low flow years.
In addition, over time, flood irrigation (compared
to sprinkler systems) has been shown to cause higher
groundwater and saturated soil problems. As a result,
there are greater losses of nutrients and pesticides
to groundwater and surface drainages. Since sprinkler
irrigation requires the diversion and application
of less water, efforts to convert from flood to sprinkler
irrigation should be undertaken so that less water
would need to be diverted from the rivers.
Noxious species of vegetation are a serious and growing
concern within this reach. Canada thistle has been
a serious problem for many years, especially within
the lower portions of this Reach (e.g. Lewis and Clark
WMA). Leafy spurge has not been a serious problem
but it has been spreading in recent years. Russian
olive has become established and appears to be thriving.
In June 2001, a field survey documented the presence
of salt cedar along the Yellowstone River in North
Dakota just downstream from the Montana border. In
2002, more salt cedar in more locations was documented,
making long-term control very challenging. Most of
these invasive species are known to be extremely detrimental.
With the exception of Russian olive, which has some
wildlife benefits, aggressive efforts should be made
to control the spread of each of these noxious species.
Adoption of agricultural best management practices
on the floodplain within this reach is another highly
desirable goal. The Reach's fish and wildlife resources
would all benefit from better livestock grazing practices,
buffer strip development and management, better timber
management practices, and proper fertilizer and pesticide
application and management.
- Riparian Aesthetics
Most of the immediate shoreline near the water surface
of the Missouri and Yellowstone rivers in this Reach
has not been heavily impacted by development or agricultural
uses. As a result, the viewscape from the river throughout
most of the Reach is mostly natural and very appealing.
However, as is the case with all river corridors,
small portions of the shoreline often become localized
dump sites. The NDGF and the USFWS have identified
a number of these sites and have prioritized them
for cleanup.
The North Dakota Department of Health has become more
active on this issue and has proposed a program that
will assist in the overall cleanup. The proposed Riverbank
Cleanup and Restoration Project would address the
removal of abandoned automobile bodies, household
white goods, and other miscellaneous waste materials
from the banks of the Missouri and Yellowstone rivers.
These waste materials can pose threats to water quality,
aquatic life and human health, in addition to being
aesthetically unpleasant. Further justification for
cleanup is the fact that these rivers are important
sources of drinking water for several communities
and rural water systems. To date, one garbage site
(spring 2000) has been cleaned up.
The river has numerous recreational uses and sites,
including Trenton Lake which is a popular summer recreation
spot. In addition, the Williston Reach is an important
spawning area for paddlefish and perhaps the endangered
pallid sturgeon. The Williston Reach will receive
much greater attention in the next several years,
as the nation prepares for and celebrates the Lewis
and Clark bicentennial. The Confluence area, including
Fort Union and Fort Buford, will be a focal point
for many visitors interested in historical and cultural
aspects of the area. Efforts to make the rivers appear
as natural and aesthetically pleasing as possible
would greatly help to insure that these visitors have
a quality experience.
- Habitat - Erickson
Island
The Erickson Island area contains some of the most
unique and valuable habitats within this reach. The
backwater area consists of about four miles of seasonally
connected (previously the main channel of the Missouri
before a cutoff was constructed) water to the Missouri
River (Figures 2 & 3 - general and detailed photo's).
The island itself consists entirely of natural floodplain
vegetation, including vast stands of cottonwoods and
willows. The stretch of the Missouri River along the
south side of the island has been documented to support
some of the highest concentrations of adult paddlefish
and pallid sturgeon found anywhere within this Reach.
The NDGFD has funded an ongoing study to quantify
the riverine habitats in this area, in an effort to
identify unique habitat requirements. Effort must
be made to protect this highly important reach from
being degraded; any development or agricultural project
proposed within or in proximity to this area should
be carefully scrutinized before it is allowed to proceed.

and Missouri rivers' confluence above Williston, North

CONCLUSION
The Williston Reach of the Missouri and Yellowstone
rivers contains some of the best remaining riverine habitats
within the entire Missouri River Basin. Although lower
Basin efforts (i.e. Nebraska, Iowa, Kansas, and Missouri)
have begun to restore and mitigate for some of the habitat
lost as a result of the massive channelization and dam
construction activities during the 1900s, the upper basin
has not. It is in our best interest to adequately protect
the limited amount of high quality, fairly natural habitat
that remains. Without adequate safeguards, it will not
be possible to maintain the reach's existing populations
of native, large river fish species, such as pallid sturgeon,
paddlefish, blue sucker, sicklefin chub and sturgeon chub.
The rivers in this reach contain numerous sandbars and
braided channels; the sandbars are seasonally used by
a number of avian species, including the listed least
tern and piping plover. Sovereign lands and the publicly
owned lands within this Reach support vast stands of native
terrestrial habitats, including self-sustaining stands
of cottonwoods and willows. These forested areas in turn
support large populations of terrestrial wildlife, such
as beaver, white-tailed deer, and pheasants. These deer
and pheasant populations support a high and increasing
amount of hunting activity. Because North Dakota contains
a relatively limited acreage of public lands, the public
and sovereign lands within this Reach are increasingly
valuable in meeting the demand for public use, including
fishing and hunting.
The enormous biological, recreational, cultural and historic
values of this Reach can only be maintained through a
concerted effort between numerous state and local governmental
entities, local landowners, hunters, anglers, and the
affected local communities. Better land use and consideration
of the needs of the rivers would go a long ways to insure
that the Reach maintains many of its most desirable attributes.
Many of these values can be protected simply by maintaining
the status quo and by carefully considering and limiting
the impacts of proposed developments.
