Little Truckee River Fish Habitat Improvement

HRS was the prime contractor on this marquee project for Trout Unlimited that improves wild trout habitat.

The Challenge

Flows within this reach of the Little Truckee River, located approximately 2 miles downstream of the Stampede Dam, have been regulated for years causing muted peak flows and the absence of a coarse sediment supply. This modified the project reach from an actively-braided channel to semi-confined, single-thread channel.

The Solution

With its limited complexity of habitats, the key elements of the project included re-introducing large woody debris and boulders; excavating backwater pools for juvenile trout rearing; transplanting willows to provide shade and cover; and adding spawning gravels to help wild trout reproduction. The combination of rootwad/boulder/willow structures will dramatically enhance fish habitat by providing refuse, cover, and deep water pools. HRS implemented several techniques for localized clean water diversion and impounding of turbid water from the construction activities.

Cost Savings

Per the project permits, no equipment was allowed to drive across the river or impact the streambed. A temporary bridge crossing would have cost over $90,000 to install and maintain for the duration of the project. The HRS team proposed to the client a value engineered alternative which included laying logs over the river to create a simple bridge so that the equipment could cross with no contact with the water. And, when the equipment work was complete these conifer logs were used on the project site. The total cost for this option was approximately $2,500. This cost-saving alternative was approved by the client and HRS successfully completed the project tasks.
