I believe they do charge a fee to fish from the bank. It's not much, like $1.00 per day I think. I've never had much luck fishing there from the bank or outside docks, although it's very nicely maintained and pleasant.

The inside fishing dock is very nice. Air conditioned in summer, heated in winter. Very clean. The ranger station is less than 100 yards away, and has security/monitoring cameras viewing the inside dock activity. Wife used to go there and fish by herself in daytime.
