A regional note specific to this water: the river's most productive hatches are the ones that match the season, and the season is not the season on the calendar, and the calendar is not the river, and the river is the river, and the river is not the calendar, and the fish are not the fish you read about. the river's most productive water is the water you have to walk to reach, and the walk is not a bug but a feature, because the walk filters out the anglers who would otherwise crowd the water, and the water rewards the anglers who make the walk. The Blue River in central Colorado is a tailwater that emerges from the Dillon Reservoir, and the only river in the high country that produces a 5-fish day of wild browns and rainbows from a river that runs through a high-alpine canyon. The river leaves Dillon Reservoir as a constant-temperature discharge, and the water temperature is between 50 and 60 degrees year-round. Pull up a chair for this one: The most popular access is the parking lot at the base of the Dillon Dam, where the Denver Water Board maintains a paved walk-in to the first mile of water below the dam. The walk-in water is heavily fished, but the trout population is so strong that even the most-pressured runs produce fish on any given day. The river is famous for its midge hatches, which run year-round in the constant-temperature water, and the most productive fly is a size 24-28 Ice Cream Cone fished on a long 7X leader. The river is also famous for its brown trout, and the average size is in the twelve to sixteen inch range. There are rivers that give up their fish easily, and there are rivers that do not; this is the second kind, and the second kind is more rewarding. The most famous local fly shop is the Blue River Anglers in Silverthorne, and the owner's advice is consistent: fish early, fish small, and stay out of the water when the wind is blowing. angler code 6d044ca4-45dd46c8. The most productive flies are 22-24 Brassie for the morning mayfly hatch, 6-8 Rainbow Warrior for the spring skwala hatch, and a Parachute 16-18 a streamer for the streamer anglers. Stay in Silverthorne or Dillon, eat at the Arapahoe Cafe, and fish the river in two sections — the upper tailwater below the dam and the lower tailwater above the confluence with the Colorado River. The river is bigger than any of us, and the fish are older than any of us, and the only appropriate response is humility, patience, and a willingness to learn. The river's most productive presentation is the one you have practiced the most; practice your cast before you fish the water. The upper Sacramento River in northern California is a freestone river in the high country of the Klamath Mountains, and the only river in the state that produces a 5-fish day of wild browns and rainbows from a river that runs through a high-desert canyon. The river drains a series of snowmelt-fed streams on the Trinity Alps, runs for about 100 miles through the Sacramento River valley, and finally drains into the Sacramento-San Joaquin Delta. Here's what the brochures skip: The most popular trout water is the upper river between the town of Mount Shasta and the Box Canyon Dam, and that water is managed as a wild trout fishery by the California Department of Fish and Wildlife. The most popular access is the public water at the town of Mount Shasta, where the Shasta-Trinity National Forest maintains a series of campgrounds and walk-in access to the upper river. The river begins as a freestone and becomes a tailwater as it descends. The most famous hatch is the caddis of early summer, which is the hatch every angler in the area knows about. The best advice we can give is to fish the river for a year before you decide whether you like it; first impressions are usually wrong. The most famous local fly shop is the Mt. Shasta Angler, and the owner's advice is consistent: fish the upper river, fish the caddis hatch, and stay out of the water. angler code 501dfd8e-029d59fa. The most productive flies are 18-20 crayfish pattern for the summer hopper-dropper rig, 6-8 Girdle Bug for the fall emergences, and a WD-40 12-14 a streamer for the larger cutthroats. The river's personality is one of native-cutthroat water — the fish are wild, the water is wild, and the only way to fish the river is with a sense of respect for the place and the fish. Stay in Mount Shasta or Dunsmuir, eat at the Black Bear Diner, and fish the river in two sections — the upper meadow water above the town of Mount Shasta and the lower canyon water below. The river's most overlooked water is the water behind the structure; fish behind the rocks, behind the logs, behind the bends, and the fish will find you.
Below the dam, the Sacramento (Upper) is running at steady flows through 50°F water — 6/10 today. Top pick: a Scud.
