I am pretty sure Pelican does not have fish as I have heard it is very shallow. I have heard about the "big gators" at Sandy before. I've tried it a few times over the past number years with little to no luck. It also supposedly had big walleye but locals tell me that both are long gone.
The Fish and Game were there trying to catch people snaring fish. Told me they are closing it for pike as its collapsed. Nevertheless I spent a solid day and had one 2lb jack.
They have a nice dock but the launch sucks. Chipped my prop up pretty bad trying to load boat back on trailer. If your in that area try Wabasca or Rock Island. Both of those have beautiful fish and Rock Island seems to be often overlooked.
