Now that October is approaching, keep track of the flow level in the Blackfoot River below the Reservoir. Any day now water impoundment in the reservoir will begin, and flow in the river below will drop to less than 200 cfs. A flow below this level results in great fishing, especially if a killing frost has not wiped out bank side terrestrial insect populations. Afternoon caddis activity should attract trout throughout the month. Dry fly fishing will be the best approach until copious submerged weed beds break up, then presenting streamers will become practical at many points in the river. So the best time to fish the river below the reservoir is just ahead.
