Rivers continue to fish well, and many are offering some outstanding dry fly-fishing. A couple of things to keep in mind: Afternoon storms can quickly muddy things up. Such is the case with the lower Colorado River. We are moving into the time of year when hot weather, coupled with low flows, can result in water temperatures exceeding 70 degrees. Please avoid fishing at those times, as it can stress fish beyond their ability to recover. Opt to fish still waters or tailwaters.
Of the area rivers, the Eagle is offering outstanding wade fishing. Excellent dry fly action is occurring; it just depends on where and when you fish as to what will work best. Patterns to have on hand should imitate pale morning duns, caddis, small stones, ants and hoppers. Nymphs are always an option when surface action is quiet; pheasant tails, prince nymphs, midges, small stones and caddis larva are always good choices.
Another opportunity that fly fishers should be alert for are damselflies. They are showing in good numbers on higher mountain waters. Ants and small beetles are also an excellent option on those breezy days, especially if the shore is willow- or tree-lined.
South Park’s Elevenmile Reservoir has been getting mixed reviews, depending on the method and time of day. Early- and late-day anglers tend to do the best. Trolling is a great way to cover a lot of water. While small spinners and spoons are a good choice, don’t overlook using small streamers, and yes, they troll well on spinning gear as well as fly rods. Weedlines are showing in abundance. These features are a good place to explore, especially if they have a deep side for pike.
Spinney Mountain Reservoir’s weeds have shown themselves, and like Elevenmile, the edges are great places to look for northern pike, as well as trout. Lots of surface action at this time, especially when the wind is down.
Speaking of pike, Williams Fork continues to produce good numbers of smaller fish in the shallows. Work the deeper edges, especially early in the day when waters are cooler, for the bigger fish. Don’t be afraid to probe as deep as 20 feet. Trophy fish like water temperatures of 60 degrees or less.
Green Mountain and Dillon reservoirs are both producing fair numbers of smaller rainbows working a variety of lures and baits. However, early and late with a fly and bubble rig is often your best bet.
