Flows have begun to decrease on the South Fork. Rollin is fishing it today and will be able to give us a good report tomorrow! Flows are currently at 16,000 cfs and will be dropping this week until they reach a base level around 13,000 cfs. Once this happens the fish will begin to move onto the bank and the riffles. Nymphing is going to be the best option for catching fish right now. Streamers will also be another good option for hooking trout. As things start to warm up in the next few weeks we could see an early Salmon Fly hatch if the reservoir doesn’t fill. We have been told there is sufficient snow in the mountains to fill Palisades, however I am skeptical from what I see in the mountains. If the reservoir does not fill above 60% we will have an early stonefly hatch and the water in August is going to be warm, forcing you to fish early in the morning and late into the evening. Granted this is just a prediction and hopefully (fingers crossed) this will not happen and the lake will fill up.
The flies you need to be fishing the next few days should be San Juan worms, Stonefly nymphs and big bead head nymphs. Weight will be important right now for getting those nymphs to the bottom of the river where the fish are holding. Don’t be afraid to fish split shot and long leaders. In regard to fishing streamers I would still be fishing a slow presentation and making sure I get those streamers as deep as I can with a sink tip line. Switch up fly size and fly color until you find the fish reacting to your streamers.
