McCormack has run way down over the years. Good place for a stick up (robbery type, needle type). Back in the 80's and 90's it was a nice place.
Then the NFS decided that fishing lakes were just a place for people to go and have fun. They would have no more of that. The dams were built before engineers had to adhere to liabilities that occur when they fail. The disaster at Taum Sauk and the payouts for that made them realize all of those dams are due to failure with age. Better just to cover them up and let them disappear.
Crane Pond Lake, Little Scotia Lake, Reynolds County Lake, The Huzzah Fish Pond Lakes by Salem have all went down hill. They used to have good fishing, but floods and hoods have made them pretty rough.
Council Bluff is still decent, but the Enough primitive campground was closed many years ago.
