While the SFWMD physically manages the water levels in the lakes by opening or closing the water control structures, the Water Management Section of the ACOE monitors and manages the multi-purpose operations of spillways, locks, pump stations, culverts, canals, reservoirs, and water conservation areas.
The ACOE also approves the regulation schedule for the lakes in Osceola County. A regulation schedule is used by water managers to manage the water levels in a lake or reservoir and is designed to balance competing objectives including water supply, flood control, navigation, and environmental enhancement. Regulation schedules are approved by the Commander of the South Atlantic Division of the ACOE.
