Navigation Notice

Notice #1 
Boaters navigating to and from Lake Okeechobee should be advised that the South Florida Water Management District (District) will close certain boat locks at the end of their normal operating hours tonight, Tuesday, April 15, 2025. Water levels in Lake Okeechobee are expected to fall below 12 feet NGVD or 10.70 feet NAVD. The following boat locks will temporarily cease operations and they will be closed to navigation until specific water levels are met. 

  • The S-135 Boat Lock at the J&S Fish Camp in Martin County.
  • The G-36 Boat Lock on Henry Creek in Okeechobee County.
  • The S-127 Boat Lock at Buckhead Ridge in Glades County.
  • The S-131 Boat Lock at Lakeport in Glades County.

The S-193 Boat Lock at Taylor Creek in Okeechobee County will be open only on Saturdays and Sundays from 5:30 a.m.-10:30 p.m. If the lake level reaches 11 feet NGVD or 9.70 feet NAVD, the S-193 Boat Lock will close on the weekends as well. Anglers and boaters may also access local waterways through other public boat ramps. Visit FWC Boat Ramp Finder to find one near you.
 

Notice #2
The South Florida Water Management District (SFWMD) changed the operating schedule of the S-310 Boat Lock in Clewiston in December 2024. The boat lock is now open to navigation from both the landside and the lakeside 24 hours a day until further notice. This means that boaters will not need to use the lock to pass through the structure. The public can get the latest navigation updates from the SFWMD by signing up for text messages and emails here. Anglers and boaters may access local waterways from several access points through public boat ramps. Visit FWC’s Boat Ramp Finder to find one near you.

The SFWMD’s Water Management Infrastructure Brochure features a detailed map of the regional water management system in Central and Southern Florida, along with key information about navigational locks, including hours of operation. The brochure also provides step-by-step instructions on how to navigate a lock.

The Kissimmee Chain of Lakes, Kissimmee River and Lake Okeechobee offer some of the best boating and fishing opportunities in Central and South Florida. Navigation locks throughout this interconnected system ensure that it is accessible by the public for recreation. 

Along the route, there are 11 locks maintained by the South Florida Water Management District and five maintained by the U.S. Army Corps of Engineers.

It takes about 15 minutes to lock through most structures. This service is free to boaters locking through during normal operating hours.
