Features
Mosquito Lake is one of the largest lakes in Ohio, and its many recreational opportunities attract both fisherman and pleasure boaters. Mosquito Lake State Park provides excellent camping and day-use facilities. The Army Corps Of Engineers completed the Mosquito Creek Dam project in 1953. The primary purpose of this reservoir is flood control and to insure an adequate domestic water supply. Because of its proximity to large populated centers, Mosquito Lake receives heavy boating pressure throughout the year. Special speed regulations are in effect. A maximum speed limit of 25 mph is posted for all waters south of the causeway. A special water skiing area is provided near the state park. Water skiing is prohibited north of the causeway and a 15 mph speed limit is enforced. A series of buoys at the far north end of the lake defines the boundary of Mosquito Lake Wildlife Area. Fishing, hunting or boating are prohibited in this area. A natural spillway is located at the upper end of the lake. When the elevation of the lake exceeds 904 feet, the lake reverses its flow. The water moves over the spillway and flows into Grand River and eventually empties into Lake Erie.
Forage
Gizzard shad is the primary forage fish for the larger predators. Spottail and common shiners are also abundant. Yellow perch, bluegill, logperch, johnny darter and bluntnose minnow also contribute to the diversity of the forage base.
Seasonal Movements
Mosquito Lake’s fish follow the typical seasonal patterns based on spawning habits.
