For Release: March 24, 2004
Irrigation season will soon be here and Lake Walcott will be refilled for irrigation, recreation and fish and wildlife. The lake is currently about 5 feet from full. Refill will begin about March 29 and the water will rise steadily until the full water surface elevation of 4245 feet is reached about April 15.
A full Lake Walcott is held behind Minidoka Dam through the spring and summer months for safety and to promote stable operation of canals, increase boating opportunities and to facilitate nesting of shore birds on the Minidoka Wildlife Refuge.
The lake will rise about 3 inches per day and the launch ramp at Walcott State Park will become usable after April 5. Boaters are cautioned that hazards that are sufficiently submerged by a full lake may be exposed or obscured by shallow water. An additional hazard is created by floating debris caused by the rising water.
To fill the lake, flows from American Falls Reservoir, located upstream about 12 miles, will be increased from the present flow of 380 cubic feet per second (cfs) to 1200 cfs on March 29 and to 1800 cfs on April 1. Flow changes will be made incrementally through the work day to avoid sudden increases in the river. Additional increases at American Falls and below Minidoka will be provided as irrigation diversions begin. Irrigation is anticipated to begin late this year but is usually well established by mid April.
