Historical River Flow

River Information

A tributary of the South Platte river, the Big Thompson begins its journey in the high elevations of RMNP. The "T" is considered a hybrid freestone/tailwater river that can be fished year round. A variety of species call this historic river home- rainbows, browns, cutthroat, and brookies are all common sights here.

Seasonal Conditions

The tailwater section is home to all of Colorado's classic hatches. The nymph stages of caddis, midges, mayflies, and stoneflies are present all year long. In the early Spring, there is a great mayfly and midge hatch that makes the water boil with risers . In the summer months, the upper portion of the T in RMNP thaws and becomes available to anglers. This meandering meadow section is best approached with big terrestrials and other dries.

River access

The tailwater is best accessed in the town of Estes Park just below Olympus Dam. There is a mix of public and private lands as you head further downstream in the canyon towards Drake. The upper T in RMNP is best accessed via the Moraine Park entrance. This section can be fished in the meadow to all the way upstream via the Fern Lake trailhead.
