Beaver Dam Analog (BDA) Installation

The contract involves the installation of up to 150 beaver dam analogs using natural materials to restore stream function and enhance aquatic habitat for the Lahontan Cutthroat Trout, a species of conservation concern. The work is focused on improving stream morphology, increasing water retention, and creating complex habitat structures that support fish spawning, rearing, and refuge during high and low flow periods. All materials used will be sourced locally and installed in a manner that mimics natural beaver activity without the use of synthetic or engineered components. This subcontract is managed by the Fish and Wildlife, Region 6 - Inland Deserts, Ontario office in California and is classified under NAICS code 238990 for other specialty trade contractors. The project is scheduled to be posted on July 7, 2026, and is intended to support broader ecological restoration goals in stream systems across the region. While specific locations and performance details are not provided, the work will take place within the jurisdiction of the California office, targeting degraded or fragmented waterways critical to the recovery of the Lahontan Cutthroat Trout population.
