Fly Fishing the Dolores River Colorado
The Dolores River is both a freestone stream and a tailwater stream. It is located in the Southwest corner of Colorado near the small town of Dolores. Its headwater section contains the Dolores and the West Branch of the Dolores River. It starts out as a small alpine meadow type stream at an elevation of about 10,000 feet. The headwaters has some private property areas and a couple of campgrounds located on the stream. The trout in the upper areas are mostly smaller fish ranging from eight to twelve inches. Fly fishing the Dolores River is best in its lower tailwater section.

When people mention the Dolores River they are usually referring to the tailwater section below McPhee Dam. The river has a very good population of trout consisting of rainbows, brown and cutthroat trout. These fish average about twelve to eighteen inches. This isn’t your average tailwater; however, as the locals put it, it requires some highly technical fishing methods. It’s more like a spring creek and in fact, normal spring creek tactics work best on the stream.

The Dolores has a very good population of aquatic insects. Its waters are very fertile. Two of the most important mayflies are the Blue-winged Olives, which hatch in the Spring and Fall, Pale Morning Duns, which hatch from late May through July. There are Green Drakes, Small Western Green Drakes, Pale Evening Duns, Mahogany Duns, Gray Drakes, Tricos and other mayflies.

Caddisflies consis mostly of Little Black Caddis (Mother’s Day Caddis), Spotted Sedges, Little Sister Caddis, Green Sedges and October Caddis.

There are plenty of stoneflies, mostly in the headwaters, but some are in the tailwater section.
Little Winter stoneflies, Little Yellow Stoneflies, Golden Stoneflies and a few Salmonflies make up the majority of them.

During the Summer months terrestrial insects become important food to imitate. Hoppers, Carpenter ants, Japanese Beetles are the most important ones.

Streamers that imitate baitfish and sculpin work year-round under low light conditions and are very important flies to use during the early Fall season.

It’s best to wait until after runoff to start fishing the Dolores. Normally this takes place in June. Fishing continues to be great well into December. The fishing regulations require the release of all trout caught. Only artificial flies and lures can be used.

This isn’t an easy stream to fish. You need to use long, light leaders and tippets. Matching the hatch can be a huge benefit. Good drag-free drifts and good presentations are usually required if one is to expect very much success.
