Lake Okeechobee Water Releases Resume November 19

ALVA, FL -- The U.S. Army Corps of Engineers (USACE) Jacksonville District will resume releases from Lake Okeechobee to the Caloosahatchee Estuary from the W.P. Franklin Lock and Dam (S-79) at a fourteen-day average pulse release of 1,200 cubic feet per second beginning Saturday, Nov. 19. No lake releases are planned for the St. Lucie Estuary.

The target is right in the middle of the REstoration COordination & VERification (RECOVER) optimal flow envelope for the Caloosahatchee. Water from the lake will only be released in amounts needed to supplement local basin runoff to meet the target of 1,200 cfs, and the target is consistent with the recommendation from the South Florida Water Management District for this week.

"Lake Okeechobee has risen three feet in the past seven weeks due to Hurricanes Ian and Nicole,” said Col. James Booth, Jacksonville District commander. “We had paused our releases for Hurricane Nicole and have not made releases since the storm. Based on conditions in the lake, we must begin releases to help manage lake levels. We have worked together with our partners and stakeholders to understand how lake releases could affect conditions in the Caloosahatchee River Estuary at this time. We are making our decision looking ahead toward next wet season and are developing a seasonal strategy where we aim to manage lake levels by making beneficial releases to the extent possible. To curtail the high-volume releases that our plan calls for right now, we are going to utilize our make-up release tool which allows us to make releases at lower levels and bank the volume not released."

Make-up releases are a water management tool within the Lake Okeechobee Regulation Schedule 2008 (LORS08) which allow water managers to bank releases not made in order to release them later when the schedule calls for lower releases. LORS08 Part D guidance currently recommends up to 4,000 cfs at S-77 and up to 1,800 cfs at S-80. The volumetric difference between actual releases and the guidance will be put into a water bank. As conditions in the estuaries recover and our schedule goes into dry season mode, releases will be continued using the available volume of banked water. Our intent is to release this volume at beneficial levels in the dry season. We are committed to transparency throughout the implementation of make-up releases.

With the lake over 16 feet, USACE has been executing inspections of the south side of the lake from Moore Haven to Belle Glade every two weeks, Once the lake reaches 16.5 feet, the frequency of inspections on the south side of the lake increase to weekly and the remainder of the dike begins receiving inspections every two weeks.

HHD was inspected thoroughly before and after Hurricanes Ian and Nicole, and no problems were identified.

Lake Okeechobee is 16.30 feet today. That is 0.16 feet higher than last week, 0.94 feet higher than 30 days ago, and 0.3 feet higher than it was on this day last year.
