Revised July 1984

ARKANSAS RIVER BASIN ABOVE KEYSTONE DAM

34b, Douglass Lake, KS
STATUS: Douglas Lake was authorized for construction by the Flood Control
Act of 1965 as a unit of a three-reservoir plan, including El Dorado and
Towanda Lakes, to help satisfy water resource needs in the Walnut River
Basin. Towanda Lake was proposed for deauthorization in 1 August 1983; El
Dorado Lake - complete. Postauthorization planning funds for Douglass Lake
were allocated for the first time in the FY84 appropriation bill. These
funds will be used to initiate a general reevaluation report.

DESCRIPTION: The damsite would be located at mile 6.7 on Little Walnut Creek
about 6 miles northeast of Douglass, Kansas. The plan of improvement
consists of a rolled-earth embankment and a controlled spillway. The
embankment would be 11,640 feet long, including the spillway, with a maximum
height of 89 feet above the streambed. Total storage of the lake would be
171,900 acre-feet, of which 76,400 acre-feet would be for flood control,
77,300 acre-feet for conservation, and 18,200 acre-feet for sediment. The
lake would provide a dependable water supply yield of 14.2 mgd. The plan of
improvement would also include water-related recreational facilities.
Douglass Lake is a unit in the plan for the control of floods in the Walnut
Ri ver Basin. The flood of record occurred in April 1944 and caused damages
estimated to be $26,171,000 (1983 prices). Floods average once every year
and have a duration of 2 days. The properties that would be protected by the
project include cropland, pasture, and oil production, with an estimated
value of $272,950,000 (1983 prices). Douglass Lake is a viable water supply
alternative for use in the Kansas State Water Policy Plan. Fifty-year
projections from the State of Kansas indicate increased demands in Sedgwick
County alone of 20 to 60 mgd. Current water supply sources will satisfy
demands only through 1985 to 1990. Construction of the project would develcp
a dependable water supply yield of 14.2 mgd.

SPONSOR: The cities of Douglass, Rose Hill, and Augusta, Kansas, and the
Butler County Board of Commissions sent letters to OMB in March 1983 in
support of the project. The Kansas Water Office (formerly Kansas Water
Resources Board), in a letter dated 9 July 1982, expressed their support of
the project and indicated their willingness to discuss their financial
participation in construction of the project at a level consistent with the
Administration's proposed upfront financing and cost sharing policies.
Congressman Robert Whitaker supports funding for the Douglass Lake project
because of the strong local support from his home district. The Central
Plains, Tri-County Planning Committee, has written letters expressing a
strong support for the Corps of Engineers to begin post authorization studies
on Douglass Lake. The Board of County Commissioners of Sedgwick County,
Kansas, has written letters expressing strong support for funds to be
appropriated to enable the Corps of Engineers to advance the Douglass Lake
project. Rapid growth of population has greatly increased the need to
develop new water supply sources.
