The Lagoon water level is regulated on a seasonal basis to optimize flood control, recreation, aesthetics, and ecological benefits. During the winter months the water level is lowered to provide a receiving basin for stormwater runoff as protection from lowland flooding. The summer water level provides optimal conditions for swimming, boating, and other recreational uses. The water level is controlled using the O’Neil Slough intake gates on the Lagoon’s south end and the Pump Station on the north end. The Pump Station’s pumping capacity and the lowering of the water level during the winter months provides the capacity to accommodate a 100-year storm event.
