Dams
However, the flow from Coyote Creek has not been very large since the completion of Casitas Dam, which forms Lake Casitas. The dam is about 2 miles upstream of the junction with the Ventura River. There is also a dam on Matilija Creek, Matilija Dam. Completed in 1948, it was built to store 5,000 acre feet (6,200,000 m3) of water, but sediment has reduced its capacity by 90%. Many groups, including some governmental ones, are working towards the removal of the dam. On November 8, 2007, the 110th Congress overturned President Bush's veto of a bill delegating approximately $89.7M to the project. Finally, Robles Dam, which is 2 miles downstream from Matilija Dam, diverts water to Lake Casitas, further reducing the river's flow.
