What it does

Existing law defines a dam to mean any artificial barrier, together with appurtenant works, that does or may impound or divert water, and meets other specified criteria. Existing law excludes from the definition a barrier that is or will be not in excess of 6 feet in height, regardless of storage capacity, or that has or will have a storage capacity not in excess of 15 acre-feet, regardless of height. Existing law requires the Department of Water Resources to supervise the construction, enlargement, alteration, repair, maintenance, operation, and removal of dams and reservoirs for the protection of life and property.
