The hydrology of the lake is influenced by its location in a Mediterranean climate zone, with most of the precipitation occurring during the winter months. The lake is fed by both surface flow and snowpack from the surrounding hills. The area around the lake is primarily used for agriculture, including vineyards and orchards, as well as recreational activities such as camping, boating, and fishing.
