About Big Thompson River - Below Lake Estes
The Big Thompson River below Lake Estes carves a path through rugged granite cliffs, defining a classic freestone stream environment. Anglers will find a landscape dominated by pocket water, where fast riffles give way to deep pools. This section of the river is easily accessed along US Highway 34, connecting Estes Park and Loveland. The canyon's cooler temperatures provide comfortable fishing conditions throughout the summer months, making it a reliable destination when lower elevation waters warm. Reading the water here means identifying the seams and eddies that form around boulders and structure, often holding fish in the transition zones between fast and slow currents. Access points are plentiful but require attention to private property. Mall Road opens up a significant 9-mile stretch of the Big Thompson, running from below Lake Estes down to Waltonia Bridge. Numerous pullouts directly off Highway 34 offer convenient entry to the river, allowing anglers to quickly reach promising water. However, it is critical to respect private land boundaries, especially as access becomes more restricted in the final four miles near the Narrows due to private ownership. Always be aware of your surroundings and ensure you are fishing legally accessible public water. The Big Thompson River is home to a healthy population of wild brown, brook, rainbow, and cutthroat trout, with common rainbow and brown trout typically averaging 10 to 14 inches. Anglers can expect productive fishing when targeting these species. During spring, Blue Winged Olives and Midges are present, offering opportunities for fine dry fly fishing. As summer progresses, drakes, Pale Morning Duns, and stoneflies become active. These periods allow for casting dry flies to rising trout, a rewarding experience for those who prefer surface presentations. Beyond surface action, the river's deep pools hold potential for larger, trophy fish. When trout are not actively feeding on the surface, focus on probing these deeper lies with subsurface patterns. Stonefly nymphs, for instance, are a consistent food source in freestone rivers and can be fished effectively with a tight-line nymphing approach or under an indicator. Pay attention to water speed and depth, adjusting your weight and presentation to get flies into the strike zone. Work the seams where faster currents meet slower water, as these are prime ambush points for trout.
