Colorado River Fishing Information
Middle Section - near Dotsero, CO
The middle section of the Colorado is often referred to as the pumphouse section though there is much more of this river to fish. The pumphouse section goes from the pumphouse put in up by kremmling down to Dotsero and the Eagle river confluence. There is a decent amount of private land in this area but several designated areas to access it via wading on public land. Floating this section is often the preferred method. Go with someone who has gone before and knows the float as there are a few rapids that can be dangerous if you don’t know the path. Hiring a guide or paying a friend in beers is a great way to get the run down on this section. This section has the most fish per mile of anywhere on the Colorado river. Tons of browns and rainbows can be caught on dries, nymphs and streamers. They get fished to often but receive less overall pressure because the waters are drifted and not waded allowing only a few shots to throw a fly to a trout before moving on.
There are some trophy trout in this section that exceed 20” if you have a good oresman, you can find them. Most of the fish will be 12” – 16” which is never a bad thing! Enjoy the river and what is has to offer on this section and refer to the map for public access wade areas.

Hatch Charts
Knowing what flies to use is only have the battle. You have to know when the insects are active on the water and when it's likely the trout are feeding on them. Refer to our hatch charts below to understand when the insect categories and some of the possible hatches on the river.
Midge Hatches
Midges hatch year round, but their importance is from September through winter into April. During the warmer months, the trout often focus on larger insects as they are more active on the water like mayflies, caddis and stoneflies.
Aside from Blue wing olives, mayflies are active most commonly from May to August in Colorado. There are many different mayfly hatches found on most rivers and the most common are listed below.
Blue Wing Olive: September throut winter to April
Colors: Green/Olive
Sizes: #16-24
Pale Morning Dun: June to Mid September
Colors: White, Yellow
Sizes: #14 - #20
Caddis Hatches
Caddis hatch starting early in May and continue to the end of October.
Colors: Olive, Green, Yellow, Tan, Orange, Brown and Black.
Sizes: #10 - #20
Stonefly Hatches
We have some great stonefly hatches in Colorado and while not all rivers carry all species of salmonflies, you can often fish stonefly adult patterns with confidence from May to September. Start off in bigger sizes and get smaller till September hits (size 8 - 16)
Golden Stone: June to August
Colors: Yellow, Tan

Yellow Sally Stonefly: Mid June to August
