Stream Reports

General Comments
Runoff appears to have peaked on most streams. Flows in the South Platte drainage are running at normal levels for this time of year due to our above average snowpack. Other areas of Colorado are still suffering from drought conditions and snowpack levels are less than historical averages; flows are therefor below normal. Double or triple nymph rigs will serve you well-use a Pheasant Tail, Two Bit Hooker, Gold Ribbed Hare's Ear or soft hackle with a midge larva or pupa trailer. Pink or purple San Juan Worms are always a good choice this time of year in high water. It's time to start trying dry/dropper rigs with a size 10-12 fly like an Amy's Ant, Chernobyl, Hippie Stomper or such like as the dry. Use a Pheasant Tail, Prince Nymph, San Juan Worm or a midge as the dropper. Caddis and Golden sones are hatching; PMDs wont be far behind. We've heard reports of good fishing on the Eagle near Wolcott, and on the North Platte at Gray Reef and Miracle Mile. Be careful wading in high water conditions. If stream runoff gets you down, try some still water fishing: local ponds and lakes are worth the time as are the Laramie Plains Lakes.

A note on bugs, hatches and fly selection:
While certain insects are actively hatching at certain times as we note below, the larval forms of all insects are always available in the stream. There may be several age classes of stoneflies, for example, at any given time; there are usually several types of caddis in most streams that hatch at different times, and trout will eat them any time they find them- same with mayflies; midges hatch almost every day, so you'll find a mix of larvae, pupae and adults almost all the time. The point we're making is that you don't always have to use a "match the hatch" approach. If bugs aren't hatching, or if your PMD imitation isn't working in July when the bugs are on the water, try a different pattern that imitates something else that lives in that stream or lake. The bugs are there, and the fish are eating them!

Give us a call before heading out as we may have some info based on what we have heard from customers and our own trips.

Current streamflow conditions are available for these and other streams at the
