South Fork 7-8-10

The fishing has really improved over the last two days. There are a lot of yellow sallies and golden stones from Cottonwood down. We had a report of the big stones flying near Twin Bridges this afternoon.

If you float through the canyon fish nymphs on the drop offs and color  changes. The dry fishing isn’t productive until you get to Cotttonwood or a little lower. The dry action should improve in this stretch as the water warms over the next few days.

The river flow is 12,500 cfs and has been steady for the past two days and there are no changes planned for several days. 12,500 is the normal summer flow at this time of year.


South Fork 7/6/2010

The river has dropped to 13,500 cfs and will be lowered another 1,000  cfs tonight to 12,500.  12,500 is the normal summer flow and the river should hold at or near this level for quite awhile. A lot of Yellow Sallies and Golden Stones are out from Wolf downriver.  A few big bugs have been seen, but no real numbers yet. Nymph fishing in the canyon with a size 4 rubberleg or Golden Stone nymph has been really good. Overall nymph fishing on the river has been very good.


South Fork 7/5

Salmon Flies have not yet started to hatch. Yellow sallies, and some Caddis are working on the Lower river. People have found success with fishing dries below Byington boat ramp. Small Sitmulators and Elk Hair Caddis. I’m not a fortune teller but I would expect Salmon Flies to be out on the lower river by mid week. Cooler water, and air temps have pushed this hatch back and at this point it is late. The majority of hatches on the other streams and rivers in our area have been late this year. Nymphing is still producing fish in good numbers. Red San Juan worms have been really effective through the canyon.

Flows were decreased this morning to 14,600 cfs. This should help the fishing and the big bugs start hatching. We will keep you updated on the latest. I have guys fishing today who will report to me this evening on the current status of the river and whats going on.


South Fork 7-2-10

As of last night there were no bug stones on the lower river below Byington.  There are a few small yellow sallies flying around so we should see some big bugs and the rest of the hatches start any day now. In the meantime the best fishing has been with a rubber leg nymph with a san juan worm or golden stone nymph dropper.

The flow is 15,800 at Irwin and 9,000 at Lorenzo. The river has a slight green tint which is normal for this time of year. A word of caution about the river below Byington. The high flows remodeled the river so there are many new brush piles and obstacles to watch for. The North Twin Bridge has two strong back eddies. One on each side of the bridge directly below the bridge.

The stonefly hatch is always fun to predict. Its not unusual to see a light hatch in the lower river and then see it suddenly appear in the lower canyon around July 4th. That may be the case this year. We’ll keep posting updates in the meantime.


South Fork 6/29

Flows this morning on the South Fork out of Irwin is at 16,300 cfs. Inflow to Palisades Reservoir has dropped and we have been informed that flows on the South Fork will decrease to 13,000 cfs. by the weekend. With this drop in flows expect the water to really start to warm up and the bug activity to start increasing. The name of the game is still nymphing, a rubberleg with some sort of dropper. If you read this report often you will already know that I prefer some type bead head nymph dropped 18-24 inches below the rubberleg. The dropper really doesn’t mater but my favorites are Prince Nymph, Red Copper John, and the Redemption nymph. The distance from your indicator to your first fly is critical this time of year. A general rule is about 7-8 feet, but with the high water I have been fishing 9-10 feet. Fish will begin to move into the pour overs and riffles as the water drops. No word on the Stonefly hatch but we will keep you updated as soon as we hear something from a reliable source. Be careful from Byington to Lorenzo, the South Channel is not passable, there is not enough water to float it. Be sure to check out the side channels before you float so you don’t get stuck. Good luck and be safe.


South Fork 6/26

The South Fork has been consistent with flows for the past week at 16,000 cfs. Flows into the reservoir have steadied out and the fishing is picking up. I was on the upper section yesterday and the nymphing was really good. We found most of our success on the rubber leg and the san juan worm. The bubble back PMD worked well in the afternoon below the rubberleg. No sign of dry flies yet. The water still needs to warm up a bit, but I would expect to see dry fly action picking up by the next weekend.


South Fork 6/23

Flows on the South Fork have been bumped to 16,ooo cfs. They are matching the outflow with the inflow to the reservoir. More snow is coming down the system from the warm temperatures. We could see an increase up to 18,000 cfs or higher if it gets really warm. So what does that mean to us as fisherman? Well the good news is were not totally screwed. Remember that fish still need to eat and they will do so no matter the water flow. Insects will not get washed away and they will hatch when the water temperature triggers that reaction. As far as clarity goes the river is in good shape and these small increases will not affect the color that much. Since fishing on the South Fork right now is primarily nymphing the fish will continue to key in on those nymphs. As we get closer to the Salmon Fly hatch they will really start to key in on Stonefly nymphs. Fish a big size 4 brown rubber leg or a Mega Prince. I would also fish a smaller stonefly nymph behind that. Yellow Sallies hatch about the same time as the Salmon flies. Big Copper Johns in a size 14 or 12, the Tungsten Yellow Sallie Nymph or the Golden Stone Nymph would be a good option to imitate the Yellow Sallie in its nymph stage. For any questions call the shop.


South Fork 6/21

Flows on the South Fork have dropped to 12,000cfs. Fishing on the river has picked up considerably with the drop in flows. Streamers, and Nymphs are your best option for catching fish right now. I would be fishing 2 rubberleg nymphs under an indicator on the banks and the riffles. San Juan worms, bead head nymphs will also produce fish.  A few notes on floating, Twin Bridges is still not accessible for floating, and will not be available for the summer. Check the side channels before you float them and make sure they are clear. Don’t forget about the new regulations that were implemented last year for camping in the canyon. You will need a fire pan, and a poop bucket that seals. You are expected to pack out what you bring in, including ashes. If you have any questions on these regulations we have some literature here are the shop for  you convenience. For any other questions call the shop.

South Fork 6/17

The flows have been dropped to 16,000 cfs today and the water report states that flows will continue to drop around 15,000 cfs by this weekend. I would expect the fishing to really pick up this weekend. San Juan worms have been the ticket for the high water, also stonefly nymphs have been really producing fish as well. With the high flows from this past week remember to check side channels for anything that would be hazardous to your boat and how it floats. Don’t let these high flows from this past week keep you from fishing the South Fork. You will find good fishing this weekend nymphing and pulling streamers. This weekend might be a great time to go camping in the canyon before the crowds come for the holiday next month. Call the shop for any questions.


South Fork 6-15-10

USBurRec will be reducing the flow out of Palisades Reservoir in 1000 cfs amounts over the next few days.  At time of this message flow out of Palisades Dam is 21300 cfs.
