Stream Reports
September 15, 2017

General Comments
It's dry fly fishing time! Summer mayflies including PMDs, Red Quills, Gray Drakes and Green Drakes can be found on most waters. Caddis, Yellow Sallies and Golden Stones are also hatching. BWOs are hatching on most tailwaters. Midges are still active, and the fish will continue to munch on them. Don't forget that there are always be stonefly nymphs in rivers and streams, as well as caddis, midge and mayfly nymphs. The creeks and lakes in RMNP are red hot with great dry fly fishing. Get there early to beat the crowds to find parking; you won't encounter many, if any, other anglers on the water. With the elk rut about to start, crowds will clog the roads around Moraine Park and Horseshoe Park. The South Platte at Deckers, Eleven Mile Canyon, in Cheesman Canyon and the Dream Stream section in South Park should be on your list for summer fishing. Other great tailwaters include the Taylor River below Taylor Park Reservoir, the Frying Pan River below Reudi Reservoir, the Yampa River below Stagecoach Reservoir, and the Blue River below Lake Dillon. The weather forecast for the upcoming week is favorable, so get out there. Keep in mind that the flows reported below are of the day of the report.  Check your favorite waters at the DNR link below for up to date flows, or go to our Real Time Stream Flows page for your favorite stream. We're hearing great stuff about the Miracle Mile and Gray Reef, too. No matter where you go, wade carefully.

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 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!

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
Colorado Department of Natural Resources.
