Fishing Report For: Colorado River
June 12th. 2024

Flows are Big!

One of the most famous river in the state, the Colorado River, is also probably the most diverse fishery as well. The section of the Colorado we fish and guide starts above the town of Kremmling and extends to the Rifle area west of Glenwood Springs – roughly 80 plus miles of floatable and wadeable river.

Many miles of the upper Colorado make its way through some of the most scenic areas in the entire country and can only be accessed by boat or hiking in. Large Browns and Rainbows as well as some native Colorado River Cutthroats inhabit this majestic river.

The Colorado is a great terrestrial river during the warmer Summer months when big fish are looking for a grasshopper falling from the banks. Spring and Fall are Streamer seasons on the “C”, that’s when we like to throw large double streamer rigs on 6 – 7wt rods for the big Pre-spawn Browns in fall and Rainbows in spring.

If you are mystified by the whole streamer program, then it’s time to get on board by taking advantage of our off-season guide rates and get out with us.

6/12/2024Flows are up

The Bureau of Reclamation is releasing a bunch of water out of most of the reservoirs on the Colorado this week. Our reservoirs are all nearly full when the run off started, so they are making room for more water. The bureau doesn’t really tell us what they are doing, so we are just waiting to see when flows will decrease.

We have added a turbidity chart to this repot. Turbidity is the measurement of water clarity. The lower the number the better the water clarity. Rule of thumb for us guides is a number 20 or less is good.

Streamer fishing from a boat this time of year can be amazing!

Flows and clarity are going to be the issues for the next couple weeks. For the best information on the Colorado near pumphouse your best bet is to call Rancho del Rio 970-653-4431. We are doing float trips on both the lower and upper C and the trout are chasing Streamers and weighted Nymphs are working best.  The Salmon fly hatch was going until the flows were increased over the weekend. Streamers and heavy Nymphs are always a go to this time of year as well.
