This reservoir was created when the Camanche Dam was built across the Mokelumne River in the 1960s. The dam and lake get their name from the former town of Camanche, that now lies deep below the surface of the water.
These days it is a popular recreation destination for all manner of outdoor activities. The day use and camping areas do fill to capacity regularly throughout the busy summer season, so early planning is essential if you don't want to miss out.
