Description
Gizzard shad is an undesirable fish species in small lakes according to the Iowa Department of Natural Resources personnel. This fish species lives in the Des Moines River, moves through Saylorville Lake, and up the spillway into Big Creek Lake. Big Creek Lake is a popular fishing lake. Since the introduction of gizzard shad, the sport fishery has declined. Quality fishing experiences have decreased and fewer anglers are coming to Big Creek. It is possible that the movement of gizzard shad from Saylorville Lake to Big Creek Lake could be curtailed through the installation of an electronic barrier or an another structural deterrent. Hydraulic modeling done as part of the planning process shows that the velocity of the water on the spillway during the critical shad movement periods is too fast to allow fish to utlize the spillway. Additional fisheries data is needed in order to proceed.
