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.

CRE Discharge Salinity Envelope - 6 months plot

Caloosahatchee Conditions Summary: Flow to the Caloosahatchee Estuary had a 7-day average of 1,640 cfs at S-79 with a 7-day average of 1,328 cfs coming from the lake at S-77. The 14-day moving average flow at S-79 is 1,857 cfs and has been in the optimal flow envelope (750 - 2100 cfs; RECOVER 2020) for 3 days.

S-77 (from Lake Okeechobee) and S-79 (to Tidal Basin) flow data along the C-43 and Caloosahatchee River. C-43 Basin Flow was calculated as the difference from S-77 and S-79.

Cumulative discharge for S-79 (to Tidal Basin) and S-77 (from Lake Okeechobee) for the last three Florida Water Years (May - April). Day of water year is analogous to day of year with Day 1 = May 1.

Salinity

Daily average bottom salinity data for the last 14-days from sampling locations within the tidal Caloosahatchee River Estuary relative to oyster health (Sanibel, Shell Point and Cape Coral) and tape grass (Vallisneria americana) health (Ft. Myers only) conditions.
