Fish Status



Bluegill were collected at a rate of 520 fish per hour in the 2021 survey. Although 31% of the Bluegill were over 6 inches, only 6% of the Bluegill were over 7 inches, and none were over 8 inches. Competition for food and resources with the abundant Gizzard Shad population is probably negatively impacting Bluegill size.



Fifteen Channel Catfish ranging from 14 to 27 inches were collected in the 2021 survey. The IDNR stocks this lake annually with Channel Catfish. Site Regulation: 6 fish daily limit.



Fifteen Black Crappie (8-11 inches) and 3 White Crappie (12-14 inches) were collected in the 2021 survey. 60% of the Black Crappie collected were 10 inches or over.



During the 2021 fall electrofishing survey, Largemouth Bass were collected at a rate of 54 fish per hour. The size distribution of Largemouth Bass in this lake is good. Of the 54 bass collected, 39% were over 14 inches, 33% were over 15 inches, and 19% were over 18 inches. Two bass were over 20 inches. The IDNR stocks this lake annually with Largemouth Bass.

Description: This scenic 248-acre lake contains a good percentage of woody habitats, which is great for attracting and holding fish.

Shore angler access is available at many areas around the lake and there is a 10 hp limit for boat motors.

History and Status of the Sport Fishery: The IDNR Division of Fisheries has been active in the management of Washington County Lake since it opened in 1962. The lake receives regular stockings of Channel Catfish and Largemouth Bass.

Warmouth, Common Carp, Golden Shiner, Redear Sunfish, Yellow Bullhead, Black Bullhead, Yellow Bass, and Green Sunfish were collected in low numbers during the 2021 survey. Gizzard Shad were collected in high numbers which is expected for a forage species.
