The Coastal Dune Lake you are talking about is Lake Powell. Does the health and maintenance of Lake Powell fall under the jurisdiction of the Walton County Coastal Dune Lake Advisory Board?
A portion of the lake is Walton County. However, the health and maintenance of the lake is overseen through a management plan developed through a seperate group called the Lake Powell Community Alliance. Walton County may be a participant but the Alliance was the driving force and there is a seperate management plan. I believe the management plan was approved in Bay County, not Walton County but am not positive.
The management plan included criteria as to opening the outfall and led to the issuance of a standing permit with FDEP as to how the outfall is managed. As someone discussed earlier, these permits are based on a trigger elevation due to health and safety risks due to high lake levels, not desire to egress and ingress the lake, submerged boat docks, etc.
Moreover, the permitted outfall location is located within the political boundaries of Bay County, and Walton County has no management authority of the outfall location in our neighboring county. In this case, I believe Camp Helen is the outfall opening location and timing of openings is coordinated by the state parks.
