And this one:

FLORIDA – OKEECHOBEE WATERWAY: Herbert Hoover Dike Rehabilitation Project Culvert C3 & C4a
Archer Western will be replacing two culverts along the Okeechobee Waterway near Clewiston (Culvert C-3) & near South Bay (Culvert C-4a) as part of the overall Herbert Hoover Dike Rehabilitation Project sponsored by the U.S. Army Corps of Engineers. Construction will occur 5 to 6 days a week, with the possibility of night time work & obstruction (Steel Cofferdam /or Barge) during the installation and removal of the cofferdams on both the lakeside and land side of the dike. Recreational and commercial boaters are asked to use caution when navigating through this section of the waterway and adjacent to the Hoover Dike Culvert C-3 & Culvert C4a. All vessels should operate as slow to idle speeds with only enough forward movement to maintain control of the vessel. Boaters are responsible for any damage from boat wakes they create. Two (2) obstruction buoys with solar powered lights, with reflective hazard warning and symbol will be placed at the outermost edge of cofferdams obstructing the waterway to delineate the cofferdam location and guide boaters through the work zone area. Once the culvert replacements are complete, the cofferdams will be removed and waterway restored. The project is anticipated to be completed by the end of July 2017.
