Numerous unnamed lakes and small rivers on Boulder Mountain and the Aquarius Plateau offer excellent fishing opportunities for hardy cutthroat and brook trout. The waters on Boulder Mountain are crystal clear and trout cruise close to the edge looking for food.

Wading can be tricky as levels change abruptly. Waders are required to counter the icy water and many leeches.

Posy Lake offers good angling for rainbow and brook trout and has a fish-cleaning station.
