Moss Lake is a reservoir located in Cooke County, Texas, near the city of Gainesville. Originally constructed in 1962 as a drinking water supply for the city, the lake is now primarily used for recreational activities such as fishing, boating, and camping. The lake covers an area of 1,190 acres and has a maximum depth of 50 feet. The hydrology of Moss Lake is primarily fed by surface water flow and snowpack from the surrounding area. The lake is also utilized for agricultural purposes such as irrigation and livestock watering. In recent years, the lake has experienced issues with algae blooms, which have prompted local officials to implement measures to improve water quality. Despite these challenges, Moss Lake remains a popular destination for outdoor enthusiasts in North Texas.
