About the North Fork Powder

The North Fork Powder River flows through the Bighorn Mountains and holds brook, brown and rainbow trout.

It mixes fast pocket water with deeper pools that hold better fish. Getting to the best water usually means hiking or a four-wheel-drive road, which keeps pressure light.

Wyoming Game and Fish rates parts of it as Red Ribbon water. It is a good pick if you want a mountain stream to yourself.
