Thank you for visiting the Chowchilla Water District Web site. As one of the largest agricultural centers in the world, the San Joaquin Valley is dependent on the surface water and groundwater that districts such as CWD provide. CWD is dedicated to providing quality water and services to the agricultural growers and communities in portions of Madera and Merced Counties. Dependable deliveries and efficient water management practices are not only policy but promises that CWD has kept for over sixty years.
