Rock Creek of the Colorado River Fishing Information
Main Section - near Kremmling, CO
This is one of those rivers that gets little attention simply because there are so many other bigger and better fisheries nearby. That isn’t to say that this place isn’t worth a day or more to explore. Often in solitude this creek can be fished up or downstream for quite a distance on the national forest areas and is a fun place to explore and get off the beaten path of the larger rivers nearby. You won’t catch any trophy sized fish here, but it’s a healthy river with good numbers and willing fish if you are sneaky. This river is a great place to work on your stealth and approach. You’ll double the amount of fish you catch here once you’ve done that well.
This river is loaded with fish, but they can be a bit fickle depending on the flows and weather. Fishing this river with some cloud cover is a good idea and when flows are up a bit ideally in the summer. Standard dries and droppers recommended below will work just fine here as the fish aren’t overly picky as long as you don’t spook them casting.
Some tips on approach. Try to stay out of the water whenever possible. Make sure to cover water as you head upstream not overlooking areas that could hold fish. Often, not covering an area will spook a trout up stream, alerting others to your presence and you’ll miss it all. Instead, fish your way slowly up the river with a couple casts in every likely spot and you’ll pick up more fish that way. I also like to release the fish downstream if they’ll cooperate so they don’t run upstream. Keep a low profile and wear neutral, natural colored clothing. Make as few of false casts as possible before casting over the fish and if possible cast to the side of the fish and let the fly pass over them without the line doing so. Practice these tips along the way and they’ll serve you well on many of your fishing adventures.

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.
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
