Check dams constructed across gullies will serve as an effective water harvesting structure like mini percolation ponds. Even though their main purpose is for controlling the development of gullies, series of check dams across a gully course will help augment the filling up of water in the existing wells nearby on both sides of the gully. Check dams is an structures built on at 500 feet distances in water canal.
