Lake Okeechobee & Caloosahatchee Estuary Tracker
The graphs below show recent elevation levels1 of Lake Okeechobee, and the corresponding rate of discharge (flow)2 of water into the Caloosahatchee River. "Lake Management Bands" comprise the background of the graphs; these bands are defined in the LOSOM. The health minimum and maximum define the optimum ranges for lake level and river flow.
1 As measured by SFWMD station LAKEOKEE, which is a composite "pseudo-station" that reports the daily mean of eight elevation gages operated by the Army Corps of Engineers (ACOE).
2 Mean daily flow of water from Lake Okeechobee into the Caloosahatchee River, as measured at the WP Franklin Lock, in cubic feet per second (cfs).
* The Lake Okeechobee Lake Stage Performance Measure indicates that an elevation of 11.5-15.5 feet supports healthy lake ecology.
** The Northern Estuaries Salinity Envelope Performance Measure indicates 750-2100 cubic feet per second supports healthy river and estuary ecology in the Caloosahatchee River. [Note: daily point is 14-day moving average of previous 14 days]
- Lake Stage (ft., NGVD)
- Lake Okeechobeee Ecological Health Min/Max*
Lake Management Bands
- High - Lake deep; flood risk. Harmfully high discharges to estuaries likely, and lake ecology at great risk.
- Intermediate - Lake deep; flood risk. Potential for harmfully high discharges to estuaries, and lake ecology at potential risk.
- Low - Lake generally in range for public safety, water supply & environmental needs. Some potential for harmfully high discharges.
- Base Flow - Lake generally in range for public safety, water supply. Environmental needs may not be met and releases needed for estuary health may or may not be provided.
- Beneficial Use - Lake generally in range for public safety, but water supply and environmental needs at risk. Releases needed for estuary health may or may not be provided.
