Older 2017 Posts:

Report - 6-3-17   Flows and color are good. Current bugs: Caddis, PMDs, Craneflies, Beetles and Ants and a few Golden Stones. Mothers day Caddis are waning, but a number of other Caddis are emerging: Spotted Sedge, Little Sister Sedge, Little Tan Short-Horned sedge and a few other smaller hatches.

Report - 5-20-17  Good caddis dry fly fishing in the late afternoon and evening yesterday. The Yakima is bumping up a bit today. Aprox. 250 cfs rise at Umtanum currently. The flow forecast from noaa predicts a continual rise until the 25th, peaking at a little over 5000 cfs

Report - 5-19-17  Caddis explosion yesterday. Poor fishing in the morning, the fish were fat and stuffed with caddis. Pretty good dry fly fishing in the afternoon after clouds moved in and in the evening. Too many bugs and too sunny until about 3 PM

Report - 5-9-17   3800 cfs at Umtanum with good color. The Yakima is in good shape from Roza to Easton. Flow projections indicate another small rise in levels peaking on Saturday followed by another rapid drop. This might compromise clarity for a few days. Grannom will be probably be the dominant hatch for a few weeks, particularly in the lower river. Other current hatches: BWOs, March Browns, Salmon flies and a couple of other varieties of caddis. PMDs should begin to emerge in the next week or two.

Report - 5-17-17   The next few days should be very good. Under 3000 cfs and good visibility at Umtanum today with a slow rise in levels predicted beginning Saturday night or Sunday. Grannom have been emerging sporadically for awhile, despite mostly cool weather. Warmer weather and light wind is forecasted from Thursday through the weekend - Grannom should explode over the next few days.  PMDs could begin emerging in better numbers as well. Salmon flies have been emerging for awhile, this hatch is always much bigger in the upper river.

Report - 5-25-17   The Yak peaked at 5900 cfs yesterday at Umtanum. Currently dropping, but still high and dirty. The noaa flow forecast for Umtanum predicts levels of aprox. 4600 by the weekend. Color could be OK by then, but sill big water.

Report - 5-31-17   The Yakima is big and off-color again after being in shape for a few days. The upper river is beginning to drop- the Yak should be in shape in a few days. Current bugs: Caddis, PMDs, Craneflies, Beetles and Ants and a few Golden Stones.

Report - 6-9-17   Big water on the Yak currently due to hot weather and then rain. The bulk of the runoff is now from high mountain snow. The reservoirs are full, so any increased flows from above run straight through.  Noaa predicts that flows will be back down to summer levels by the 12th or 13th.

Fishing Report - 6-12-17   The Yak is back. Cool weather the last few days dropped the river at Umtanum from 5700 cfs on Saturday to 3200 cfs today. Current hatches: PMDs, Caddis and an assortment of smaller hatches.

Fishing Report - 6-26-17   Aprox. 2600 cfs at Umtanum, unusually low for late June. Water temps are still good despite the low water and hot weather over the last few days. Fair to good nymphing. Decent dry fly fishing in the lower river during the evening caddis emergence. Current hatches: PMDs, Caddis, Yellow Sallys and terrestrials in the lower river and PMDs, Caddis, Yellow Sallys, Green Drakes, Golden Stones and terrestrials in the upper river. The hatches have been pretty light, lots of sunny weather.

Fishing Report - 7-8-17   The Yakima is in great shape and is close to normal summer levels- 3500 cfs at Umtanum. The Summer Stones emergence is beginning to build and morning and evening big dry fly fishing should continue to get better. OK to good nymphing during the sunny portions of the day. Current hatches: Summer Stones, Caddis (spotted sedge-Little Tan Short-Horned sedge) Yellow Sallys, Crane Flies and Terrestrials (ants, beetles and immature hoppers).

Fishing Report - 7-28-17 Water levels are currently fluctuating between 4100 cfs and 4200 cfs at Umtanum, still in the normal summer flow range. High water temps in the Canyon have been 60 degrees or lower. Best dry fly fishing morning and evening. Big drys have been mediocre to fair. Evening Caddis - OK to good. Mediocre to fair nymphing during the sunny portions of the day.

Fuller’s teasel and Swallowtail

Fishing Report - 8-1-17   4275 cfs at Umtanum today, a bit higher than average summer levels. The weatherman is predicting 100 degrees or higher for the rest of the week, so a little extra water in the Yakima will keep water temps down. Fair to good nymphing the last few days. A few more fish willing to take a dry fly during the day, but still much better early morning and evening.
