Yup, the Nasty flows through the fort. Used to be pretty easy to access. Nowadays almost impossible. Do believe now you have to know EXACTLY when you want to fish it, then get a pass for that day, then reverify when you want to fish it. Heard it's pretty tough. But the Nasty used to be a terrific salmon and steelhead river. Have some chummers hitting that river pretty quick. You CAN get on, you just need to find out what it takes nowadays. I know we used to be able to get a multiweek pass back in the day.
It's easy to get a pass, go to the main gate, get a visitor pass, then go to Range control, and get a pass that's good for an entire year. Then call the number on the pass to check the area you want to fish for the given day, and if it's clear, go fish it. Very rarely are there live fire excercises that spoil your fishing. Make sure to display the vehicle pass on your dash, and carry the personal one in your wallet, doesn't cost any money, either. Bob.
