WGI performed a specific purpose survey of the C-43 Canal (Caloosahatchee River) beginning at the Moore Haven Lock at Lake Okeechobee, and ending west of the Franklin Lock in Fort Myers (approximately 49.1 miles). The survey was performed through three counties: Glades, Hendry, and Lee counties. Survey services included research of record documents, calculating right-of-way, retracement of over 1,100 right-of-way monuments, GPS observations, digital photos, setting carsonite witness posts, creating CAD files, and creating an inventory spreadsheet. Due to some of the remote areas this project traversed, as well as the potential contentious access limitations through adjacent private property owners, this project was accessed entirely by multiple survey vessels within the right-of-way of the canal. Some other challenges encountered during the course of the survey work was extensive line cutting, steep banks where the boat and personnel needed to access upland areas, limited boat launch areas, and dangerous wildlife such as snakes and alligators.
