Lewis & Clark Lake Largemouth and Smallmouth Bass

These regulations apply to waters of the Missouri River from Gavins Point Dam upstream to Fort Randall Dam.

Largemouth bass are annually sampled by electrofishing backwater areas in the Niobrara Delta. In 2014 the number of largemouth per hour of electrofishing was above average. The 2011 flood severely altered the backwater habitats within the delta which resulted in altered largemouth bass distribution within the delta. Traditionally, the best largemouth bass angling on Lewis and Clark Lake has been found in backwater areas of the Niobrara Delta containing aquatic vegetation. 

Smallmouth bass are abundant throughout the reservoir from Gavins Point Dam to the Fort Randall Dam tailwater. Most of the population is young and tends to be on the small side; however, some smallmouth bass near 18 inches are sampled each year.
