VENTURA — The City of Ventura supplies water to its residents from three main sources: the Ventura River, Lake Casitas, and three groundwater sources.
In the early 1900s, an underground dam was built across the Ventura River in Foster Park to supply water to the growing city of Ventura. However, construction of the dam was halted about 300 feet short of the design due to the increasing depth of bedrock and rising inflow of groundwater.
