A beautiful quiet community, Lake Warren is a private lake located 5 miles north of Monmouth, IL on Route 67. The lake is managed by the board of directors of the Hickory Grove Lake Company. It is a man-made 52-acre, spring-fed lake with 2-1/2 miles around the perimeter.
In 1949, several men in Warren County had a vision of having a private lake in Warren County. George C. Shuman, who later became President, Walter McMaster, Olen Bryant, and Taylor Mitchell, took the imitative to start the ball rolling. They contacted the Illinois Department of Conservation who sent one of their engineers, L. D. Putman, a faithful and invaluable aid in the development of the lake. Together they selected the present sight of Lake Warren; about 171 acres on the west side of Route 67 five miles north of Monmouth.
This man-made lake was to cover 72 acres and be 27 feet deep at the dam. The 700 foot dam was 150 feet wide at the bottom, with a 35’wide road across the top and was equipped with a drain for cleaning. Members were able to lease lots for $10 per year. This allowed them to clear the lot and either build a cottage, cabin, or to just place picnic tables and fireplaces to use for various activities. At that time, no swimming was allowed. Most of the road work was finished in time for the lakes first annual fish fry on Sunday, August 24th, 1952. By the end of the summer, the lake was stocked with 500 baby bass, 300 adult bass, 2,000 crappies, 2,000 bluegills, 2,000 catfish and 5,000 walleyes. In 1954, the lake enjoyed their second full year of operation with approximately 75 cabins and trailers that had been erected and installed. Excitingly, the beach was used by over 300 people in a single afternoon and fishing had an excellent turnout as well. Currently, there are array of families from across the United States that occupy homes surrounding the lake and enjoy the privileges that come from living around such a beautifully hand-crafted lake.
