The U.S. Army Corps of Engineers, Jacksonville District is urging boaters on Lake Okeechobee to use caution as a result of falling water levels impacting navigation routes. The Corps issued a Notice to Navigation yesterday (June 15), advising commercial and recreational vessels to use extreme caution while traveling Okeechobee Waterway Route 2 between Port Mayaca and Clewiston. Officials are also asking boaters to use caution in the waterway between Clewiston and Moore Haven as temporary dams associated with rehabilitation work on the Herbert Hoover Dike have created a narrow channel at multiple locations.
