Purpose

This webpage/report is intended to aggregate information from different agencies (i.e. USACE, SFWMD, FWC, USGS and NOAA) into one spot to help inform local government agencies and stakeholders on conditions within Lake Okeechobee, the Northern Estuaries and the Everglades ecosystem. The data provided here should be considered preliminary and are subject to change.

Northern Estuaries

Caloosahatchee River Estuary

Discharge Conditions

Daily and 14-day moving average discharge for S-79 relative to the Northern Estuaries RECOVER performance measure for the recent 30-day period.

Caloosahatchee Conditions Summary: Flow to the Caloosahatchee Estuary had a 7-day average of 4,379 cfs at S-79 with a 7-day average of 0 cfs coming from the lake at S-77. The 14-day moving average flow at S-79 is 5,411 cfs and has been in the damaging flow envelope (> 2600 cfs; RECOVER 2020) for 14 days.
