Intent To Prepare a Draft Environmental Impact Statement (DEIS)
for the Lake Tohopekaliga Extreme Drawdown and Habitat Enhancement,
Osceola County, FL

AGENCY: U.S. Army Corps of Engineers, DoD.

ACTION: Notice of intent.

-----------------------------------------------------------------------

SUMMARY: The Jacksonville District, U.S. Army Corps of Engineers
(Corps), the Florida Fish and Wildlife Conservation Commission, and the
South Florida Water Management District intend to prepare a Draft
Environmental Impact Statement (DEIS) on the feasibility of
implementing a plan for the Lake Tohopekaliga Extreme Drawdown and
Habitat Enhancement Project, Osceola County, Florida.

FOR FURTHER INFORMATION CONTACT: Questions about the proposed action
and DEIS may be addressed to Ms. Heather Carolan or Ms. Lizabeth R.
Manners, U.S. Army Engineer District, P.O. Box 4970, Jacksonville,
Florida 32232-0019; Telephone 904-232-2016/3923.

SUPPLEMENTARY INFORMATION:

1. Proposed Project

    a. Lake Tohopekaliga, located in Central Florida, has previously
undergone three extreme drawdowns in 1971, 1979, and 1987. The
drawdowns are designed to improve aquatic habitat that has been
negatively impacted by flood control practices, which have resulted in
detrimental stable lake levels and nutrient enrichment. Following
refill of Lake Tohopekaliga after the three previous drawdowns the
numbers of fish food organisms, sport fish and forage fish increased
significantly; new aquatic vegetation communities became established;
and organic sediments decreased in the lakes.
    b. The purpose of this project is to improve the environmental
ecosystem of Lake Tohopekaliga and thus provide quality habitat for
fisheries, birds and other wildlife. Beneficial effects associated with
the drawdown plan include bottom substrate improvements as organic
build-up is reduced. Reduction of muck will lead to an increase in
diversity and density of desirable vegetation. The drawdown will also
allow the control of nuisance aquatic plants, such as hydrilla, water
hyacinth, cattails, alligator weed, smartweed and pickerelweed, which
proliferate under the unnatural static lake level conditions. In
addition, the water quality of Lake Tohopekaliga will be enhanced by
the nutrient uptake and filtration abilities by the recruitment of
native plant species. Restoring littoral habitat, which favors bass,
will increase native fish species.
    c. Approximately 2,844 acres (40%) of shoreline along Lake
Tohopekaliga will be exposed during the drawdown. Organic bottom
sediments should compact and consolidate during the scheduled low water
period. Coverage of beneficial aquatic vegetation such as knotgrass,
maidencane and bulrush should increase following refill due to
germination of seeds exposed during the drawdown. The subsequent
increase in vegetation communities should significantly increase fish
food organisms and sport fish populations.
    d. Muck removal will be performed to enhance aquatic habitat and
improve

boating conditions. Approximately 5 million cubic yards of organic
material will be removed. The material will be disposed of on upland
sites or used to create in-lake wildlife islands. Wildlife islands
serve as excellent rookery sites for wading birds and also serve as
resting and basking areas for reptiles.

2. Alternatives

    a. Several drawdown alternatives will be identified and evaluated
during the study.
    b. Potential environmental resources and issues to be evaluated in
the DEIS include project impacts on:
    (1) Fish and wildlife resources.
    (2) Wetlands resources.
    (3) Wildlife habitat & values.
    (4) Vegetation.
    (5) Water quality.
    (6) Surface & groundwater resources.
    (7) Endangered or threatened species.
    (8) Historical or archeological resources.
    (9) Aesthetics.
    (10) Nuisance and exotic plant species.
    (11) Downstream effects.
    (12) Air quality & noise.
    (13) Soils.
    (14) Navigation and recreation.
    (15) Freeze protection.
    (16) Local tropical fish farms.
    c. Because of the magnitude and duration of this project the U.S.
Army Corps of Engineers, the Florida Fish and Wildlife Conservation
Commission and the South Florida Water Management District have
determined that a DEIS should be prepared for the Project pursuant to
the National Environmental Policy Act (NEPA).

3. Scoping

    The scoping process as outlined by the Council on Environmental
Quality will be utilized to involve Federal, State, and local agencies;
and other interested persons and organizations. A scoping letter will
be sent to interested Federal, State, local agencies and interested
parties requesting comments and concerns regarding issues to consider
during the study. Responses to this letter will help identify the
potential environmental impacts to be evaluated in the DEIS. Additional
comments are welcome and may be provided to the above address. Public
meetings may be held in the future. Exact dates, times, and locations
will be published in local papers.

4. Schedule

    It is estimated that the DEIS will be available to the public by
the spring of 2001.
