The U.S. Army Corps of Engineers Jacksonville District will reduce flows from Lake Okeechobee to the St. Lucie Estuary while maintaining the current release schedule to the Caloosahatchee over the next week.

Starting Saturday, March 16, the Corps will maintain the current pulse release to the Caloosahatchee estuary at a 7-day average rate of 1,800 cubic feet per second from the W.P. Franklin Lock and Dam (S-79). The Corps will reduce the flows to the St. Lucie estuary down to an average 7-day pulse release of 250 cubic feet per second as measured at the St. Lucie Lock and Dam (S-80). This decision will be reviewed again next week. Additional runoff from rain in the Caloosahatchee and St. Lucie basins could occasionally result in flows that exceed one or both targets.

“Our strategy to reverse the rise of the lake has been successful so far,” said Col. Andrew Kelly, Jacksonville District Commander. “We’ve been able to bring the lake down more than a half foot over the past three weeks. We are making a slight adjustment to the St. Lucie release to help with oyster spawning in the estuary.”

“We are maintaining our current pulse releases to the Caloosahatchee, in an effort to continue to lower lake levels without causing any significant impacts to the estuaries,” said Kelly. “An additional two to three inches of rain is forecast, which will increase the runoff in the canals, limiting our ability to release water from the lake.”

Kelly says the Corps doesn’t intend to drive the water level to a specific target. “We are looking for results, rather than trying to hit a specific number,” he said.

Today’s lake stage is 12.33 feet above sea level, which is in Operational Beneficial Use Sub-Band. During the past week, lake levels were reduced by 0.24 feet, with an overall 0.36 foot reduction in the past 30 days.  The Corps will continue to monitor conditions and adjust flows as necessary. Any changes in flows to the estuaries will be announced to the public.
