Stream Reports
May 20, 2017

General Comments
Runoff is here. This week's snow and rain will probably increase flows as it melts. Continued warm weather will probably keep flows above normal. Check the updated flows before heading out. BWOs are hatching around the state and we're seeing some locally as well. Midges are still active, and the fish will continue to munch on them. There have been a few sightings of small caddis; the usual spring caddis hatch in happening on the Arkansas, up to the Salida area. Don't forget that there are always be stonefly nymphs in rivers and streams. Streams below about 10000 feet are open, and in some cases our warm weather has gotten an early runoff started. The North and South St Vrain are producing, as are the Big Thompson, North St Vrain  (Wild Basin) and Glacier Creek in RMNP. The North St Vrain in the Wild Basin area of RMNP is open and fishable. We've heard good reports from the Poudre, the Arkansas in Canon City and above. High country lakes are still frozen, but the Delaneys and Spinney are open. 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 spring 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. The Delaneys are fishing well, and the Laramie Plains lakes are yielding some BIG fish. We're hearing great sytuff about the Miracle Mile and Gray Reek, 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.
