Grundy County Lake

This area is Grundy County's newest recreation area. The 40-acre lake was created by IDOT in 1999 when borrow material was needed for the highway construction. The IDOT transferred the area to Grundy County by agreement upon completion of the highway project.

The lake site was transferred to Grundy County in August, 2002. Additional property was purchased from the IDOT using Resource Enhancement and Protection (REAP) grant funds making the total area 255-acres.

Construction of the boat ramp and access drives around the lake began in 2002 and the park officially opened to the public in July, 2003.

Since that time, trees have been planted and native prairie grass seeded. And continuing over the next few years, planned developments include shelters and picnic facilities. Wetlands and other habitat restoration has been done. An asphalt hiking/biking trail was constructed cooperatively with the city of Dike in the summer of 2008. A 61-site modern campground development is now complete.


The park is located on the south side of Highway 20 by the city of Dike.  Easy to get to from wherever you are coming from.
