General Comments
Streams are finally more or less at normal levels for this time of year, and the fish are hungry. Locally, we've heard reports of good fishing on the North St Vrain at Buttonrock, the South St Vrain along CO 7 and The combined St Vrain in Lyons. the Poudre around and above Rustic. Rocky Mountain National Park streams are in great shape and fishing really well. Hatches of PMDs and Red Quills are hatching, but in fairly small numbers. Dry/dropper rigs will serve you well= use a Para Adams, Elk Hair Caddis or attractor dry up top with a Pheasant Tail, Two Bit Hooker, Gold Ribbed Hare's Ear or soft hackle as the dropper.

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.

Note: Fly patterns in red are Laughing Grizzly exclusives.
