South Fork 9/11

Flow out of Palisades Dam was dropped to 10,000 cfs early on 9/09. That small amount will not impact fishing, but look for more flow decreases out of the dam coming up. We will pass them on in this fishing report to help you plan a South Fork trip and to help understand conditions on the river. For now stick to hopper types, foam or otherwise, close to banks. With cloudy or stormy conditions, be ready with BWO and mahogany dun life cycle patterns, and don’t forget those streamer patterns.


South Fork 9/8

Flow out of Palisades Dam has been steady at around 10500 cfs, but change are coming, so more walk-in wade fishing location will be available. For now float fishing results in more opportunities. Present your hopper and chernobyls close to banks with cover when drifting, but do not overlook parking the boat and wade to explore side channels. Where cover is present fish these channels thoroughly as many are not fished by those who simply drift down the river. Towards mid week some cloudy weather is forecast, so if you are on the river then be sure to have BWO and mahogany dun life cycle patterns. This time of year always carry streamers and a sink tip line.


South Fork 9/5

Flow out of Palisades Dam remains same for time being. Mutant stones are still active, and #6-8 green or red Chernobyl ant or Elden’s golden Stone, same sizes, is a good pattern for them. Mahogany duns and BWOs are out, and fish are keying on them mainly on cloudy or stormy days. Hoppers pitched close to banks remain productive. Crowds are down, and weather is at its best. So it is a great time to be on the South Fork.


South Fork 9/2

Flow out of Palisades Dam has remained constant at just above 10,000 cfs because of late demand for water by the agricultural community. Look for flows to drop later this month. Meanwhile, stick to the hoppers and other terrestrial patterns close to banks. We have a few reports of BWOs and mahogany duns and fish taking them along the river during our cooler weather this last weekend, so best include patterns for these in your fly box when weather like we just had during the second half of Labor Day happens. These will be important emergences later this month. See the patterns we recommend for these in the pane on the left. Also be sure to have streamers in your fly boxes if you will be on the river early or late in the day.


South Fork 8/29

The flow dropped 1500 cfs last night and this morning to 10,500 cfs. While it may slow the fishing a little it will cause the wingless golden stones to be more active which should keep the chernobyl ant patterns producing. We may start to see some blue wing olive mayflies as the weather cools as expected later this weekend. The river below Lorenzo not far above the Henry’s Fork confluence has cleared up and appears stabilized after cutting a new channel.


South Fork 8/26

Flow out of Palisades Dam has dropped to 12000 cfs. This small amount should not impact fish activity, but look for flows to continue to drop as USBurRec begins storing water for the next irrigation season. Labor Day weekend is an important one for most anglers, so if we learn of any flow change out of Palisades Dam, we will post them here. Meanwhile, stick to those terrestrial patterns tight to the banks, and don’t overlook streamer patterns in the same locations especially early or late in the day. Mutant stoneflies are out making for some AM fishing. Also do not overlook the evening caddis activity.


South Fork 8/22

Flows have not dropped at quite the rate that US Bureau of Reclamation predicted, and even if they go down a few hundred cfs at a time, don’t look for a big impact on fishing success. But count on flows to drop to around historic levels by Labor Day weekend. Meanwhile, Hoppers and other terrestrials close to banks and overhead cover brings the best results up and down the river. Don’t overlook pitching a streamer to the same places, especially during evenings.


South Fork 8/18

Flows are still about 12900 cfs out of Palisades Dam. BUT: tonight they will drop 500 cfs, and tomorrow night (8/20) another 500 cfs. Look for flows out of Palisades to drop under 10,000 cfs soon after Labor Day. Get in touch with us if you have questions on this news. Hoppers and other terrestrial insects are the way to go. Don’t overlook the idea of a trailing pattern, too. For those considering a trip on the river below Lorenzo, the river is cutting a new channel on the lower end. This is making for discolored water down to Menan, so streamers and nymphs may be the best way to go on the lower end of your trip.


South Fork 8/14

Hopper patterns are really attracting fish throughout the river, and look for this to continue for a while. But do not overlook attaching an ant or beetle pattern as a “trailer”. Present this rig as tight to grassy banks as you can get. Presentation is much more important than choice of pattern, but get in touch with us if you need recommendations. Fishing the riffles is tougher now that the PMD emergence peak has passed, but you can still find some action by closely watching riffles. Where you see fish working, stop & give it a try. Also caddis swarms are making for good evening action along the river.


South Fork 8/11

The riffles are getting tougher for action as fish there are getting very selective. This applies all up and down the river. Consider that the riffles have been “hammered” for weeks. These days the best way to find action is by pitching hoppers tight to the banks. This also applies up and down the river.
