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 544 cfs at S-79 with a 7-day average of 464 cfs coming from the lake at S-77. The 14-day moving average flow at S-79 is 469 cfs and has been in the low flow envelope (< 750 cfs; RECOVER 2020) for 159 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.

St Lucie River Estuary

Discharge Conditions

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

St Lucie Conditions Summary: Flow to the St Lucie Estuary had a 7-day average of 38 cfs from North and South Forks with a 7-day average of 290 cfs coming from the lake at S-308.

S-308 (from Lake Okeechobee), S-80 (to Lower Fork), C-44 Basin and North Fork (Gordy Rd, S49, S48) daily discharge. C-44 Basin Flow was calculated as the difference from S-308 and S-80.

Cumulative discharge for S-80 (to Tidal Basin) and S-308 (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 St Lucie River Estuary relative to oyster health conditions.

Lake Worth Lagoon

Discharge Conditions

Daily and 14-day moving average discharge for discharge to the Lake Worth Lagoon for the recent 30-day period.

Lake Worth Lagoon Conditions Summary: Flow to the Lake Worth Lagoon Estuary had a 7-day average of 416 cfs, with 15 cfs from S44, 307 cfs from S155 and 94 cfs from S41.

Cumulative total (S44, S155, S41) discharge for to Lake Worth Lagoon 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 Lake Worth Lagoon. LWL20A is location north of Southern Blvd; LWL19 is located Lake/Lucerne Ave.
