Lewis and Clark Lake Largemouth and Smallmouth Bass Regulations (For more information on Missouri River Regulations, see 2009 Fishing Handbook, pages 20-23)

*These regulations apply to waters of the Missouri River from Gavins Point Dam upstream to the SD-Nebraska border to the point where the river becomes entirely in SD.

• Smallmouth/Largemouth Bass (in any combination)-5 fish daily/10 Possession

Largemouth bass were sampled by electrofishing backwater areas in the Niobrara Delta.  Number of largemouth per hour of electrofishing was just above average and included fish up to 18 inches long.  Traditionally, the best largemouth bass angling on Lewis and Clark Lake has been found in areas of the Niobrara Delta containing aquatic vegetation.

Smallmouth bass are abundant throughout the reservoir from Gavins Point Dam to the Fort Randall tailwaters.  Most of the population is young and tends to be on the small side; however, some smallmouth bass up to 19 inches were sampled in 2008.

Other Species

Additional opportunities for anglers pursuing other gamefish species exist on Lewis and Clark Lake.  White bass congregations can be found at certain times of the year with many in the 10 to 15 inch length range.  Crappie holes exist in the area near Springfield, SD known as the Niobrara delta.  Once located, crappie fishing can be excellent in these areas.
