Fish Status



The Bluegill population contains numerous fish up to 7.0 inches with the potential to catch fish up to 8 inches. Anglers will have to wade through smaller fish to find the larger ones.



The Largemouth Bass population is dominated by 12- 14 inch fish. These fish have good weights and are in good overall health. Trophy potential is low, but good catch rates can be expected at Lake Carlton. Age and growth data confirms good growth until age 5, 13 inches, and slowed growth after age 5.


Very Good

Muskie are stocked in Lake Carlton to provide a top line predator species. Muskie are stocked at a rate of 1 fish per acre every other year. Muskie ranging from 30-38 inches are the dominate size group.

SAUGEYE (Walleye/Sauger Hybrid)


Saugeye fishing will continue to be good, but fishing for them takes some dedication. Good numbers of fish 14-22 inches long are available. Spring samples have averaged 76 fish/hr for the past 4 years. Numbers for fish over 22 inches have been steady at 10 fish/hr.

History and Status of the Sport Fishery: Lake Carlton is a watershed impoundment constructed in 1969 by building a 38-foot high, 1,800-foot long earthen dam across a stream. The lake was named in memory of L. Carlton Anderson, a local citizen who actively promoted the park and was an important civic and conservation leader.
