Warm weather and low river flows has Colorado Parks and Wildlife (CPW) calling on anglers to check water temperatures and avoid fishing trout waters when temperatures climb into the 70's. For reinforcement, signs are posted on parts of the Eagle River requesting anglers not fish after 2 p.m.
The Eagle River is fishing well in the morning when waters are cooler. Caddis larva, pale morning duns and emerger patterns have been successful. Be careful wading, as conditions are slick.
Near the Eagle is Sylvan Lake, where fly fishers report the Calibaetis mayflies are emerging throughout the day, offering good action. Small streamers and spoons are also producing good action.
Lower Blue River flows have been cut back to 330 cfs. due to recent rains downstream on the Colorado. That will make fishing slightly more challenging on the Blue. Expect to encounter off-colored water conditions on the Colorado River on occasion due to storms. Don't quit fishing under those conditions, though. Instead, change up to big dark streamers. Otherwise, midges and small mayfly patterns such as pheasant tail fished as a dropper with a hopper will produce.
Green Mountain Reservoir has been generally slow, but for those wishing to stock up on suckers for winter mackinaw fishing will find the suckers are biting fairly well.
Be aware that on Friday, Williams Fork Reservoir will be closed to trailered and motorized water craft. Only small car-top hand-launched craft, such as canoes, bellyboats, kayaks and other smaller vessels will be able to access the reservoir.
Boaters will continue to be able to launch at most other area waters, such as Grand Lake, Shadow Mountain, Granby, Wolford and Dillon reservoirs.
