Project Summary:
McDermitt Creek and its upper tributaries harbor the Lahontan cutthroat trout (LCT), a federally threatened species.  This native species is in jeopardy of losing its genetic identity due to hybridization with non-native rainbow trout and loss of habitat due to exotic fish that inhabit the lower reaches of McDermitt Creek.  Over the last decade, U.S. Fish and Wildlife Service, Oregon Department of Fish and Game, and Nevada Department of Wildlife have placed several temporary barriers to protect LCT and prevent non-native fish from moving upstream.  Otis Bay designed a permanent fish barrier to prevent upstream migration of non-native fish in McDermitt Creek.  To accomplish this, Otis Bay completed topographic surveys, hydraulic and hydrologic analyses, and geotechnical surveys to develop a fish barrier design, which was provided to the U.S. Fish and Wildlife Service in a final report.  In June of 2010, Otis Bay subcontracted with Otis Bay Ecological Restoration to install a permanent fish barrier on lower McDermitt Creek.

Project Update:
A construction sequence and Best Management Practices (BMP) report was submitted in August 2009.  Construction of the fish barrier was completed in June 2010.
