September is one of the best months to fly fish in Montana. Fall is in the air and with it comes perfect conditions for fly fishing. The strong summer hatches of terrestrials continue often through the end of the month, and good hatches of caddisflies and mayflies can be expected by the middle of the month on the Missouri River, Yellowstone River, and Madison River.
