Wicka is a privately owned earth dam located in Dodge, Trempealeau County, Wisconsin. Built in 1965 by the USDA NRCS, Wicka serves primarily for recreational purposes. Standing at 38 feet high and spanning 340 feet in length, this dam has a storage capacity of 60 acre-feet.

Despite its low hazard potential, Wicka poses a moderate risk due to its uncontrolled spillway and outlet gates. While the condition assessment is not available, the dam is inspected every 10 years to ensure its safety. With the risk assessment rating at a moderate level (3), Wicka remains a significant structure in the Tr Latch Valley Creek area, managed and funded by the Natural Resources Conservation Service.
