  • USACE increases target flows from Lake Okeechobee to the Caloosahatchee Estuary

    The U.S. Army Corps of Engineers (USACE) Jacksonville District will increase releases from Lake Okeechobee to the Caloosahatchee River Estuary beginning Saturday, June 10. The releases to the Caloosahatchee River Estuary will target a pulse release at a 7-day average of 2,000 cubic feet per second (cfs) from the W.P. Franklin Lock and Dam (S-79). This is a slight increase from the 1,800 cfs targeted pulse release that has been in effect since April 15. Since this target is measured at the W.P. Franklin Lock and Dam (S-79), it includes local basin runoff and may require flows at S-79 to temporarily go above the target release to maintain flood control along the C-43 Canal.
