About the East

The East River is a high alpine stream that flows through the valley near Crested Butte and joins the Taylor River at Almont to form the Gunnison. It is Gold Medal water with clear flows, willow banks and deep, slow bends that hold big wild fish.

The fish are brown trout and rainbow trout. In fall, kokanee salmon run up from Blue Mesa Reservoir, and trout key in on their eggs. Unlike the neighboring Taylor, the East is a natural freestone that rises and falls with snowpack.

Much of the river runs through private ranches, so public water is limited. Know where you are and keep to marked access. Spring Creek, the Slate River and Cement Creek are nearby options when the East is busy.

Peak insect hatches come in July and August. Pale morning duns, green drakes, salmonflies and golden stoneflies all show up, and late summer belongs to hoppers. The kokanee run draws anglers in late September.

Check the current Colorado Parks and Wildlife regulations. Some stretches have their own rules.

Tips for fishing the East

  • Respect private land

    Much of the East runs across private ranches. Use public access points and do not cross fences or banks without permission.

  • Fish the bends

    Big fish hold in the deep, slow bends under willows. Approach low and quietly.

  • Plan around runoff

    The river rises with snowpack. Wait until it drops and clears before you expect good dry fly water.

  • Carry hoppers and egg patterns

    Hopper Juans work in late summer. Egg patterns catch trout feeding behind the kokanee in fall.

  • Look at the neighbors

    The Taylor River, Slate River and Cement Creek are close and make good backup plans.
