Mosquito Lake was first created in 1840, when a dam was built across
Mosquito Creek in the low, swampy region of Champaign County known as Mosquito Creek Valley to build a grist and
saw mill. After operations at the mill were shut down, the dam and lake were neglected for several years. In 1932, John W. Kiser and his family owned the land and donated several hundred acres to the State of Ohio to rebuild the lake for recreational purposes. In 1939, work on the dam started, and in 1940, all work was completed on the dam and Kiser Lake was filled. The lake is maintained by the
Ohio Department of Natural Resources. ==References==
