Stream Reports
July 8, 2022
 

General Comments
Runoff on the Front Range is still flowing fairly high on most streams..Elsewhere in the state., especially in the southwest. streams are in midseason form. That bodes ill for streamflows in that part of Colorado and may necessitate stream closures later this year because of warm water temperatures. PMDs are starting to pop here and there., and caddis are hatching on many streams across the state. Summer dry fly fishing is not far away, but for now, dry/dropper or nymph rigs are the order of the day.

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
Colorado Division of Water Resources.
