Yakima River Fishing Report

What is new?

I-82 was closed last night due to a wildfire but is back open and the wildfire seems to be contained. We are not seeing smoke anymore except for a little haze occasionally, so enjoy the clean air! We are in for some wind this Sunday as well as Saturday night, but Friday looks very calm as of now. 

We just got the new Sage Signal which is a killer, easy casting, saltwater rod. It is perfect for anglers who want to buy once and never again, but can't justify spending $1000 (or more) on a rod. We have been impressed with how easily it can pick up and drop 50' casts in 20 mph winds. Compared to the R8 salt it feels slightly heavier and little stiffer, but not by much. Joe's detailed review is here.

If you are looking for a trout spey or full spey rod ahead of the fall fishing season, we have the new classic spey and olympus from Redington. In addition we are selling Dually's and Claymore's at a steep discount and have plenty in stock. While these are the older generation they are still excellent sticks and we are still fishing them! Here's a review a spey lesson in Alaska casting for Grayling using a claymore, watch here!

We are running our new raffle supporting Project Healing Waters. Visit the shop to buy a $10 ticket for a chance to win a new Winston Air 2 9' 5wt! The drawing will take place October 1st, and we will call the winner as well as announce the drawing on our social media. Through these raffles, our customers have helped raise thousands to put veterans on the water, so lets keep it going! 

Fishing should be better in the mornings still, and with the smoke gone the sun should be better able to warm up the water. Watch the water temps in the afternoons but also expect fishing to slow once the sun gets high in the sky. Dry flies have been working well, and this time of year do not be afraid to throw big hoppers or stone flies. 

We are still running our voluntary hoot owl closure for our guide trips. This means that trips will stop fishing by 2pm. Full day trips will aim to launch at 6am if possible, and half days will leave before 10. This is a voluntary closure, and more information is available lower in the report. If you are fishing on your own there is no legal requirement preventing you from fishing in the afternoon, but pay attention to water temps, land fish quick, and expect slow fishing during the heat of the day.

Current Fishing

Our flows have steady and are currently around ~3,200 CFS. Our summer flows have been consistent but expect them to drop in the next couple weeks. Our flip-flop is around the corner. This is when the dams reduce their releases and typically happens around Labor day.

With higher water temps think about making some changes to your fishing. Carry a thermometer and check water temps, consider stopping when they 70. Leave the 7x at home. Fight fish hard to bring them in quick, you can pull very hard on fish with 4x or even 5x without breaking your line. Most trout should not take over a minute to land, and for their survival in warm water it is important to keep fights under that minute mark. Don't do a grip and grin, get creative and take your pictures with the fish in the water. 

Fishing can be good during the day but will be mostly a nymphing game. Mid afternoon fishing has been slow, and will continue to be slow with high water temps, but fish can still be caught. Contact nymphing can be effective in pockets and turbulent water, even during this time. If you are fishing dry flies in the daylight focus on structure. The fish are tight to the banks, under submerged trees, and around boulders. The closer to the bank the better when casting. If you can't make it that far try landing your fly in front and right on the edge of boulders and over fallen trees. They will be in shade, under cover, and tucked close to anything that hides them from predators and the heat. 

Anglers are still getting fish on stoneflies, on top and underwater, and we are seeing  caddis coming off and laying eggs at night. Even if you don't see stoneflies on the surface don't be afraid to tie on a big dry!  The trout are keyed on hoppers and stones right now and expect to see them coming past. Caddis are a great choice right now too, splashy rises at dusk often indicating feeding activity on emerging pupa. Mayfly spinners at last light can produce as well. 

Our water temperatures are starting to hit 70 and with air temps remaining high through the day and night we have begun a hoot owl closure. This is a voluntary closure and not required of recreational anglers, but is worth thinking about as an individual. As heavy users of this resource we feel it is necessary to limit our impact as best we can, so we choose to not fish when it can be harmful to the fishery. Additionally trout fishing slows greatly in 70+ degree water. Expect slow fishing and poor fighting fish as well if fishing in 70+ degree water but they can be caught. 

Hoot owl closures are closures on trout fishing after 2pm. At 70 degrees water contains too little oxygen for trout to properly rest after a stressful fight and release. After a few days of water temps in the 70's there is a good chance that trout are unable to rest and purge the lactic acid from their system--killing the fish. A fish swimming off strong is never a true indication that they will survive the release, and this is doubly true in warm water.

Our water outlook for the season is still looking solid! Reservoir storage across the Yakima Basin is currently roughly 150,000 acre-feet higher than it was this time last year. While we're still just below the long-term historical average, it's excellent news for anglers. Expect healthy flows to stick around throughout the summer, keeping trout positioned along the banks and providing the kind of consistent conditions both fish and anglers love.

Where the Trout Will Be

The most productive water continues to be:

  • Outside bends and cutbanks
  • Soft seams along fast banks
  • Current breaks behind structure
  • Shallow water tight against grassy shorelines
  • Eddies and softer pockets along the bank

Tactics That Matter Right Now

  • Fish large stonefly and caddis dries early and late in the day.

  • During midday, switch to a dry-dropper setup or a short-leash nymph rig.

  • Cloud cover can extend dry fly opportunities well into the afternoon.

  • Focus on accurate casts tight to the bank, especially when fishing stoneflies and hoppers.

Wading vs. Floating

At approximately 3,500 CFS, the Yakima is still on the high side for wading. While there are certainly places to get out and fish, wading should be approached cautiously. As a general rule, stay in water below knee height and avoid crossing fast current. Floating remains the most effective way to cover water and access productive holding lies.

We have GREAT water storage in the reservoir network right now, at this time we have +/- 150,000 acre/feet more than last year at this time. While it's slightly below the historic average, it should make for high flows all summer long. Just the way the trout and the anglers like it!

Naches River Fishing Report

The river is still low but is still fishing. Please make sure to check water temperatures if you are going to fish the Naches and aim to fish the morning, as it has been hitting the high 60's in the afternoon. Dries will be the name of the game with low flows currently, but nymphs and streamers can always produce. Consider some of the higher elevation streams and tributaries in the area if the Naches is getting too hot! We still have some opportunities for guided float trips. but the flows are dropping quickly. By the time we get you booked, we might only be able to run single-angler trips (1 angler + 1 guide). Just email dallas@redsflyshop.com to try and carve out a date! We additionally offer walk and wade fishing on the Naches if that is of interest. 

Small Stream Fishing is Here!

With the Yakima running high and healthy, now is also an excellent time to explore the region's smaller mountain streams. With our snowpack being reduced this year don't be surprised if a few of the streams you know are lower than normal. But many of these creeks are in their prime conditions, with flows dropping into shape and eager wild trout looking up for dry flies throughout the day. Look at tributaries a long the Yakima and Naches river! Whether you're hiking into a favorite blue-line creek or exploring new water, summer offers some of the year's most enjoyable small-stream fishing and a welcome change of pace from the big river.

Yakima River Flow Prediction Chart

While the chart is only a "prediction", it is based on historical data, weather forecasts, current weather, current snow-pack etc. You can use this to get a rough idea of how the river is going to react to predicted rainfall, run-off, etc.
