This species is stocked each year as 8-10" fingerling fish.
Location: Lake Eureka is located within the city limits of Eureka in Woodford County, Illinois. The lake is surrounded by a city park that offers playground and day-use facilities for the general public.
Description: Lake Eureka is a 30 acre impoundment located on Walnut Creek which is a tributary to Panther Creek and the Mackinaw River. The lake was built in the early 1940s as part of a public works project (WPA), to provide a potable water source for the City of Eureka. Lake Eureka provided drinking water until 1982, when wells replaced the water needed by the city. Lake Eureka is quite shallow and very fertile. Average depth for Lake Eureka is approximately 6.5 feet with a maximum depth of 12.8 feet. The lake has a very large watershed that includes approximately 1,300 acres of row crops. It receives significant loads of sediment from the cultivated watershed and both total alkalinities and dissolved solids are quite high. Lake Eureka is surrounded by manicured, lawn-like shore. It is 100% accessible for shoreline access and is "kid friendly", for bank fishing.
History and Status of the Sport Fishery: Lake Eureka was built in the early 1940s as a WPA project to create a safe water source for the City of Eureka. In the early 1980s, the water intakes of the intake tower became obstructed. At that time, a proposal to use wells for water was designed and built. Because the lake was no longer a potable water supply, it was rehabilitated using rotenone to remove a very bad fish population. The lake was immediately restocked with largemouth bass, bluegill and channel catfish. An excellent game fish population resulted from the rehabilitation work.
NOTE: The fish kill in the winter of 2013-2014 caused most of the game fish in this lake to be killed. After investigating the loss of fish, the IDNR introduced more game fish brood stock from other lakes. However, the only fish species that survived the winter-kill situation in Lake Eureka were common carp, which were able to get an unlimited spawn in 2014. Some of the large brood carp were 25 to thirty pounds and were able to produce millions of eggs into a relatively de-populated fishery. These fish are now the most abundant fish in Lake Eureka and have created very turbid water (all game fish need clear water to survive and flourish). Unfortunately, the only way to remove carp is to remove the entire population and start over again. The game fish currently being caught in Lake Eureka are those that we stocked, hoping to control carp by predator pressure, which is not working! The IDNR will not try to rehabilitate the lake using a draw-down until 2017, after most of the desirable fish are harvested from the lake. At such time, the lake will be drawn down.
Additional Lake Information: There is a single lane concrete boat ramp all boat access is controlled by a permit from the City of Eureka. No gas powered motors are allowed and launching of larger boats is difficult. No minnow fishing is allowed.
