Fishing Report - Los Pinos River

November 29, 2020

The flows have dropped to 5 CFS on the Pine. The fish are held up in the deepest holes and are super spooky. The are on the constant lookout for predators. We won't be back on the Pine until spring, usually April, when water returns from Vallecito Reservoir for irrigation. This is the absolute best time of fish the Pine all year. When the water returns and fish feed constantly. The flows go up slowing and you are able to fish a lot more water than at normal summer flows. Book a trip, we promise you won't regret it.


As of: September 14, 2021

The Los Pinos has been our best fishery during the late summer months. Dry fly fishing has been ok, but we are producing more fish with a nymph rig. It's a tail-water, so small patterns are the best.

September and October can be some of the best fishing of the year when the water levels start to drop. We get some great fall hatches and streamer fishing. We should have good fishing conditions until mid October.

The Pine is now over 1400 cfs. Don't let the big flows bother you. We had great days last year with flows over 1000. The fish will find the soft water and will stack up there. Bug stones, caddis and streamers will catch fish. Both of our private sections are great at high water. Give us a call to inquire about our guided trips.

Flows have returned and the fishing is great. Nymphing caddis larva, mayfly emergers, and stone flies have been producing the best. The water is slowly climbing and will only get better. We are offering guided wade trips on the Pine at 2 different properties. If you are interested please give us a call. There is a little section of public water in the town of Backfield. Have fun and watch for big bugs. Check out our instragram for pictures of the Pine.

The flows are still too low to fish. In the next couple weeks we should see the water start to go up. When this happens, the fishing will be excellent. Hoping things will get back to normal soon and we can get out there.

Let us know if we can fill any orders for flies or accessories.

Thanks and stay safe and healthy.

With low water and ice on the river fishing is tough. Look ahead to March/April for the first chance to get on the Pine after the winter break. If you can find some open water that has some deep holes fish small nymphs. Once the water goes up in the spring, we experience some of the best fishing of the year.

The Pine river has been dropped down to 30 cfs. Conditions are tough but still fish-able. A stealthy approach is key! Low flows should continue until spring. Enjoy fishing until the winter weather sets in.

Fall is the absolute best time of year! Water conditions have dropped and fall colors are fantastic. We have been catching a lot of beautiful rainbows and browns over 16 inches. Nymphing has been most productive but still getting a couple on dry flies. Fall is the best time to fish streamers on the Pine. Hatches are smaller and less consistent so the fish are looking for a big meal. Water levels should stay great for fishing for the next month. Book a trip and get on the Pine!

The Los Pinos River below Vallecito Reservoir has been fishing very consistent. Big caddis hatches and PMD's are happening daily. There are a lot of fish looking up and dry fly action has been good. Still producing most fish nymphing but streamer fishing has been picking up. The fall months are the best time of year to fish streamers. If you'd like to take a real trophy on a streamer consider and fall trip on the Pine! If you feel like hiking, the Los Pinos above Vallecito has been on fire in the Weminuche Wilderness.

The Pine river is in prime shape and fishing has been lights out! We are having solid action on dry flies and streamers, while nymphing is still most productive. The flows have stabilized around 620 cfs and the trout have settled into typical feeding patterns. Caddis, Mayfly and Stone flies hatches are coming off the river. Mid morning until dark has been the most productive times. Fantastic fishing should continue the rest of the season.

With Vallecito Lake filling to capacity last week the flows on the Lower Pine river have been all over the place. It has fluctuated from 2500 cfs to 800 cfs. Keep an eye on the gauge, if the flow has been stable the fishing should be good. Streamers have been moving fish, and fishing hoppers down by Bayfield has been productive. The Caddis hatches have been heavy in the afternoons, and there are still some stoneflies coming off. We have been hooking up to fish in some of the faster water, so be sure to cover the whole river when you fish, they aren't always holding in the obvious spots. Look for the flows to stabilize over the next few weeks as spring runoff ends.

The Los Pinos River is experiencing above average flows with Vallecito Reservoir filling up quickly. Normal conditions are between 400 to 800 cfs through the summer months. Currently, we are experiencing the river around 2300 cfs. While most of the river is big and moving fast, the water is fairly clear. There are still fishing opportunities to be had despite the flows. Heavy nymph rigs and long leaders are essential for success. Big water can produce big fish!

Fishing is excellent/consistent over the last week. Flows are slowly increasing but not enough to affect the fish. Nymphing has been producing the most fish with an occasional streamer follow and eat. Without a doubt the best river conditions in Southwest CO at the moment. If your interested in fishing the Pine, don't hesitate to contact us!

This tail-water river is currently the regions most consistent fishery. Flows around 300 CFS are ideal to target trophy fish, enough water to provide cover for the fish, but not too much for the angler to wade. Quality rainbows and browns are being landed with a few solid shots at some much bigger fish. Conditions won't last long with higher flows forecasted in the next few weeks. Call the shop for further questions or to book your spot.

The river flows are up and the fishing is excellent. All winter the flows remained around 5 cfs and now we are experiencing flows around 355 cfs. The fish are feeding aggressively and are not picky. Streamers and nymphs and producing fish with consistency. Still a little early for dry flies. The water is holding steady but is expected to increase in the coming weeks. This is a fantastic river that holds trophy fish. Call the shop to book, we promise it's worth it!
