The Eagle River has officially settled into summer mode, and anglers should expect classic low-water conditions across much of the river. With a below-average snowpack and an abbreviated runoff, flows are well below what we typically see this time of year, making stealth, precise presentations, and responsible angling more important than ever. Current conditions have produced excellent clarity, but warming water temperatures mean trout become increasingly stressed during the afternoon hours.
The best fishing window is from first light through late morning, when water temperatures are at their coolest and trout are actively feeding. By early afternoon it is time to start checking water temps regularly, at least every hour. On freestone river like the Eagle, conditions can change rapidly. Carrying a stream thermometer is highly recommended throughout July, especially on the lower river. If temperatures approach 67-70°F, it is time to call it day or move upstream to cooler water. 
Dry fly fishing continues to improve each week. Caddis are now the primary hatch and can provide excellent evening fishing upstream of Edwards, where water temps are still low enough to fish all day. Pale Morning Duns (PMDs) are showing throughout the valley, and red quills are present in solid numbers. Early terrestrials—including ants and small beetles—are beginning to produce, and hopper fishing should continue to improve over the coming weeks. Nymphing remains productive by focusing on deeper runs, undercut banks, and faster pocket water where trout can stay comfortable in cooler, oxygen-rich currents.
The lower Eagle—from Edwards through Gypsum and down toward Dotsero—is currently providing some of the better fishing on the river, but it also experiences the warmest water temperatures. Anglers willing to get on the water before sunrise are finding aggressive trout feeding on caddis emergers and PMDs before the heat of the day sets in. Tricos have also started showing up early this year due to the low water and warm weather. As the sun gets higher, trout slide into deeper buckets, shaded banks, and heavier current where oxygen levels remain higher. Fishing slows considerably during the afternoon, and anglers should closely monitor water temperatures before continuing to fish. The lower Eagle is also beginning to transition into terrestrial season. Small terrestrial patterns, like the PMX and Amy’s Ant are producing along grassy banks, and hopper fishing should continue to improve as summer progresses. Overall, the Eagle River is fishing well for those willing to adapt to the conditions. Fish early, handle trout carefully, minimize fight times, and release fish quickly while keeping them in the water. Responsible fishing during periods of low flows and warm water helps ensure the Eagle remains a world-class trout fishery throughout the summer.
