Abstract

Three proposed operation plans for the Winnebago pool, Wis., were studied to determine the effects on lake stage and discharge. A digital reservoir simulation model simulated daily lake stage and discharge from the Winnebago pool. Inflow for this simulation was computed from daily discharge, recorded at Rapide Croche Dam, and daily stage, recorded at Oshkosh. This computed inflow is net inflow, combining the effects of streamflow, precipitation, evaporation, and net groundwater inflow. The model adjusted discharge daily to keep lake stage close to the proposed operation plan. By doing this and by lowering the pool level to near the minimum stage in winter, the plan reduced the frequency of stages exceeding the maximum allowed stage. For the 61 years simulated (water years 1918-78), the simulated 7-day, 10-year low flow at Rapide Croche Dam was 1 ,000 cubic feet per second compared to 900 cubic feet per second for the observed record. The 7-day, 2-year low flow was 1,500 cubic feet per second (simulated) versus 1,600 cubic feet per second (observed). The study showed that discharge from the Winnebago pool could be managed to guarantee a release of up to 1,500 cubic feet per second, but with occasional violations of the minimum stage requirement.
