We have plotted the Lat/Lon position given in the message below, cherry picked from the latest Local Notice to Mariners, and it appears that the described construction is taking place on the canal-like portion of the Okeechobee Waterway between Clewiston and Moore Haven, probably near charted “Liberty Point.” And, notice that this construction is ongoing until Spring of 2015.
All mariners navigating the OKWW between Clewiston and Moore Haven should be on the lookout for the below described construction vessels, and pass this equipment with minimum wake.
The Salty Southeast Cruisers’ Net is declaring a Navigational Alert for these waters.

FLORIDA-OKEECHOBEE WATERWAY: Herbert Hoover Dike Rehabilitation Project (Update September 28, 2012).
Odebrecht Construction, Inc. will be replacing two culverts along the Okeechobee Waterway near Moore Haven (Culverts 1 and 1A) as part of the overall Herbert Hoover Dike Rehabilitation Project sponsored by the U.S. Army Corps of Engineers. Construction consists of the steel and earthen cofferdams on both the lakeside and landside of the dike to create a self contained work area. The waterway will be restricted and may be intermittently obstructed during the installation and removal of the cofferdams and during the process of replacing the culverts. Recreational and
commercial boaters are asked to use caution and be prepared to stop when navigating through this section of the waterway between the Alvin L Ward park boat ramps and Uncle Joe’s Fish Camp boat ramps. Flagmen will be present as needed to signal vessels to stop or to proceed with caution. The controlling width through Culvert 1A project area is 20ft minimum, limited by a controlling depth of 6ft when the lake is at elevation +11.0ft Mean Sea Level. Once the culvert replacements are complete, the cofferdams will be removed and waterway restored. Construction will occur 5 to 6 days a week, with the possibility of night time work. The project is anticipated to be completed in spring of 2015. The Project point of contact is Elizabeth Lamborghini at 305-704-5848. Chart 11428
