Description

This small watershed impoundment of 26 acres is owned by the City of Monmouth and managed for fishing by the Illinois Department of Natural Resources. The lake has a south basin of 17.7 acres with a maximum depth of 33 feet and a north basin of 8.3 acres with maximum depth of 13 feet. The two basins are connected by a short channel that is spanned by a historic 1895 bridge. In 2016, the bridge was dedicated to Ken Russell the longtime IDNR district fisheries biologist who helped relocate the bridge to Citizen’s Lake. Most of the 1.4 miles of shoreline is accessible to bank fishing. Boat ramps are available on both basins and a small trailer campground is situated near the north lake basin.

Fishery History

The lake and its sport fishery are evaluated annually by a fall electrofishing survey. This survey directs the fish stockings, fishing regulations and aquatic vegetation treatments. Since 1994, the water level at Citizen's Lake has been drawn down 5.5 feet in early September as a major fish management practice. The annual fall drawdown increases the predation of small fish, which favors an increased rate of growth in both the predator and prey species. A repeating fish kill occurred from September 2018 into the spring of 2019 at Citizen's Lake. It was believed to have started as a low dissolved oxygen fish kill and then developed into a bacterial fish kill. The fish kill was severe on the south half of the lake and moderate on the north half of the lake. The kill appeared to remove all of the Gizzard Shad and Black Crappie populations and only left young-of-year Largemouth Bass, Bluegill and Green Sunfish. In 2019, the lake was restocked with Largemouth Bass, Channel Catfish, Redear Sunfish, Blacknose Hybrid Crappie and Rainbow Trout.
