It looks like the US Bureau of Reclamation is keeping their word of about 900 cfs coming out of Palisades dam as a winter maintenance flow. The Irwin gage is not ice up, nor is the Heise gage ( about 1200 cfs), but the Lorenzo gage currently is. It’s a tough time for salmonids in the river, so any flow increase would be to their benefit. Merry Christmas and happy new year to you all and to those trout that the river hosts.

We are at the winter maintenance flow out of Palisades Reservoir; around 900 cfs, Flow is slightly better downstream after most tributaries enter: around 1100 cfs from Heise on down. Look for these flows to remain much the same through the winter and on to irrigation season beginning. As much water as possible from run-off will be captured in Palisades Reservoir.

Flow out of Palisades Reservoir is now 938 cfs (1150, cfs at Heise, 1190 cfs at Lorenzo) on its way down to river winter maintenance flow of 900 cfs.

Please avoid disturbing and fishing through brown trout redds being established up and down the river. These are in the process of making the future brown trout population which we will enjoy!

Flow out of Palisades Reservoir was dropped to 1330 cfs last night. Flow at Heise is a bit higher temporarily, and the same at Lorenzo. The temporarily high flow at Lorenzo is because upstream canals have been turned off. Winter flow is proposed to be 900 cfs.

Walk-in-wade fishing is the way to go with these low flows throughout the river which makes it tough on hard-sided boats. Brown trout are migrating throughout the river..Flows have not reduced significantly since our last fishing report, and we hope they do not decrease further with winter just around the corner.

Flow continues to drop: now 2200 cfs at Irwin, 2000 cfs at Heise, 1200 cfs at Lorenzo. Great for walk-in-wade fishing, tough on hard sided boats. Let’s hope further drops are very small with winter, the toughest time for fish, not far away.

Flow out of Palisades Dam was dropped five days ago and so are leaves. Flow is about 3000 cfs Irwin, 2700 cfs at Heise, and 1200 cfs at Lorenzo. Great news for walk-in-wade fishing! More great news is that we will have good BWO weather for a while and likewise good conditions for streamer fishing. Hoppers will have a tough time becoming active, and boating will require some caution because of the “skinnier” water.

Leaves are falling, daytime hours are diminishing and flow out of Palisades Dam (now 3070 cfs at Irwin, 3250 cfs at Heise,1700 cfs at Lorenzo) is decreasing. This is to the joy of walk-in-wade fly fishers who have more locations to try and brings caution for those using boats.Unsettled weather is predicted for the upcoming weekend. Let’s hope that BWOs and mahogany duns take advantage of the increased overhead cover then and that trout now concentrated in deeper water come up to feed on the increased surface activity..

If you are a walk-in wade fly fisher, the South Fork is now a “piece of heaven.” Flows have decreased significantly ( now about 4500 cfs at Irwin, 4200 cfs at Heise, 2100 cfs at Lorenzo) and will do so further as the irrigation season winds down and Palisades Reservoir, presently at 10% of capacity, needs to be filled . So the choice of walk-in-wade locations on the river below are quite numerous. We can help in choosing locations to fish, so get in touch. With the fall colors, fine weather, concentrated fish populations, and safer wading the river is now as inviting as it can be.
