I will check on Mary as I may be wrong but it was my understanding that she had left the CDL Board, but she is still on the County's CDL website. I don't remember who would have filled that position but will try to find that out also.
I was thinking of the Retreat, Watercolor and Watersound as the three communities not the distinct pieces. Please be aware that Deer Lake, Camp Creek, or Draper have never been opened "officially" by anyone, unless DuneLaker knows of a time way back, and in today's permitting climate it is not getting any easier to get permits for new lake openings.
The opening of the lakes are due to emergency conditions and impacts to structures on upland properties that would lisk health and safety. Not docks and accesory structures, but septic tanks and major habitable structures. To that point, I am unaware of any St. Joe property that would meet those conditions as they are set back from the wtaer's edge far enough that the triggering event would be a single family residence outside the property boundries of a St. Joe community.
As for Lake Powell, I do not believe that they would ever get the state and/or federal permits to open and maintain an opening. Furthermore, if they did I am very confident that Walton County would stringently object due to the downdrift impacts caused from the opening of the channel. it would most likely lead to downdrift erosion of the Camp Helen/Inlet Beach area (which is already deemed "critically eroded" by the state), and impacts might be observed in the Rosemary Beach area. Moreover, the actual pass would be unable to maintained without structures leading to even more permitting and impacts. I guess my point is that on the state and federal levels the likelihood of this occurring is extremely slim.
