Position 5 Flood Control
Prevent flooding while providing more open water.
- Restore the water elevation to 872 ft. (12 to 14 inches above the current level)
- Dredge the accumulated vegetation back to pre-encroachment boundaries. (see DNR warning under water depth tab)
- Identify other areas of low water vegetation encroachment and dredge accumulated litter.
- Identify gathering area/entry point components into the new weir design and construction. (This is a neighborhood entry point.)
(See the water depth tab for pictures of 2003 water level and DNR directives, and the historic battle over water level in 1945.)
1. Outlet controls
Bass Lake and Twin Lakes now lack controls to maintain water levels during periods of low precipitation. Stable water levels would protect plant and wildlife communities, improve aesthetic qualities of the water body, and may reduce odor-producing growth.
Example: Curtiss Pond Improvement Project, Falcon Heights 2014
Features: Forecast – based control system, OptiRTC. The system monitors National Weather Service data, and adjusts outlet control to accommodate rainstorm inflows.
