Matilija Dam

Reservoir Levels Weather Hydrology

Matilija Dam is a structure located in Ventura County, California. It was built in 1948 primarily to control floods and provide water for agriculture, domestic, and industrial purposes. The dam is 200 feet high and 530 feet wide and has a storage capacity of 7,000 acre-feet. The Matilija Creek watershed covers 114 square miles and is an important source of surface flow and snowpack providers for the surrounding areas. The dam has been a topic of controversy due to the significant amount of sediment build-up behind it and the negative impact on the environment and fish populations. The dam is currently being considered for removal or modification to restore the natural flow of the creek and allow for the revitalization of the ecosystem. The area around the dam is a popular recreational site for hiking, fishing, and camping.
