LAKE OKEECHOBEE HYDROGRAPHIC SURVEY

Pahokee, FL

WGI performed a hydrographic survey on the southeast shore of Lake Okeechobee to facilitate the design of offshore barrier islands proposed to be created from dredged material in an effort to protect the Pahokee Marina during future storm events.

The final product provided an underwater view to determine the quantities of material available to design the islands. In addition to the area around the marina, sub-bottom profiles were conducted on the existing Route 2 Channel to determine if the soil could be used as a source of additional dredge material.

During this phase of the survey, a total of 32 miles of sub-bottom profile line was conducted and the transects in the marina area totaled approximately 83 miles of survey lines, creating the basis for the final contour map. To complete the elevations above the waterline, dual-frequency GPS rovers provided the fastest and most accurate method. The offshore and onshore information was combined within CAD software to create the base map for the final engineering design.
