Mann Lake Headgate, operating since the early 1900's, diverts water from three tributaries of Sweetwater Creek to the Lewiston Orchards Irrigation District (LOID) and provides water to the "Orchards" section, City of Lewiston. Stream habitat above this site receives continuous flow from a spring and several tributaries carrying irrigation water from Soldiers Meadow Reservoir in the Waha Mountains southeast of Lewiston, Idaho. Adult "A" steelhead cannot ascend the face of the low head diversion dam except under high flows that offer limited access over a 12-15 foot lift . Summer diversion often captures all flow above the dam, terminating juvenile downstream migration in Mann Lake.
Project start year 1996 End year 1997
Start of operation and/or maintenance 1997
Project development phase Planning
Maintenance of "A" steelhead runs to upper Sweetwater Creek.Lewiston Orchards Irrigation District water diversion.
Biological results achieved
Annual reports and technical papers
Habitat improvement to allow passage of juveniles and adults.
Specific measureable objectives
Increased steelhead runs through Lapwai Creek and Sweetwater Creek. Prevent extinction of Sweetwater Creek "A" steelhead run.
Adult passage and juvenile passage will improve run size in Lapwai and Sweetwater Creek drainages.
Underlying assumptions or critical constraints
Lewiston Orchards Irrigation District will allow installation of juvenile screen and adult pass in conjunction with their low head irrigation diversion dam.
To be determined
Brief schedule of activities
1996: Coordination with LOID, IDFG, NPT. Planning and predesign and complete report.1997: Construction of adult passage and installation of juvenile screen and diversion.
Provide access to spawning grounds and rearing habitat; prevent juvenile loss in irrigation diversion.
Summary of expected outcome
Increased "A" steelhead runs into Lapwai and Sweetwater creeks.Elimination of juveniles being diverted into Mann's Lake.
Dependencies/opportunities for cooperation
Cooperative project between LOID, NPT, IDFG.Potential to cost share with LOID.
Natural calamities, weather conditions, soil conditions beyond control of project.
Monitor and maintain adult passage and juvenile screen.Adult and juvenile monitoring by NPT Idaho Salmon Supplementation studies.
