Abstract: Bussey Lake is a backwater lake located in lower pool 10 of the Upper Mississippi River on the west (right descending) side of the river, approximately 1 to 2 miles upstream of lock and dam 10. The project area is within the Upper Mississippi River Wildlife and Fish Refuge and is located in Clayton County, Iowa. Immediately adjacent to the lake is the city of Guttenberg, Iowa. The next closest major city is Dubuque, Iowa, about 30 miles downstream. The overall purpose of this project is rehabilitation, enhancement, and maintenance of diverse habitat for fish (primarily centrarchids, particularly bluegill) in Bussey Lake. The good fish habitat that was created after the lake level was raised by the construction of the lock and dam system in the 1930's has been gradually declining. The two primary and interrelated causal factors contributing to this decline are the deposition of sediment and the resulting excessive growth of aquatic plants in the shallower parts of the lake. A secondary problem within the lake system has been the potential for contamination of the lake with pesticides, herbicides, and nutrient input carried by runoff from the Buck Creek watershed. This drainage area overflows into the upstream end of Bussey Lake during high runoff periods. This study focuses on proposed project features that will rehabilitate the deteriorating fish habitat within Bussey Lake and that will help preserve and protect this improved habitat. The project was planned for the benefit of the Upper Mississippi River fishery and will be consistent with refuge management goals and economic considerations.
