Report Summary for Jul 2026
This year: The Dolores River is currently experiencing low flows, holding steady around 20-25 CFS. Water temperatures are quite cold, ranging from 34-38°F, with gin-clear clarity throughout the system. Fishing has been tough under these conditions, but opportunities exist for persistent anglers. Anglers should focus on the primary hatches of Midges and Baetis. Nymphing with small patterns will be your best bet, particularly during the late morning to mid-afternoon. Effective flies include the Zebra Midge, RS2, Top Secret Midge, and a Blue Wing Olive.
Best time of day: Afternoon
Prior years: The Dolores River is experiencing low flows, with the flow at the town of Dolores recorded at 105 cfs. Freestone sections of the upper Dolores are also seeing low water levels. As flows drop, bug size tends to decrease. Fishing has been really good, particularly with strong mayfly hatches occurring throughout the day. This makes it an ideal time for dry fly fishing. Anglers can expect to see Tricos, Blue Wing Olives, small drakes, hoppers, ants, and other terrestrial bugs on the water. Be aware of rising water temperatures on the lower portions of the river.
