Project Gallery Five - Conner Creek, Trinity County
The goal for this project is to provide full passage for all life stages of fish by removing two County road culverts that prevented  migration. In addition, sediment reduction and additional capacity for storm events and allow passage of debris from the 2008 Eagle fire which impacted the area.

The Conner Creek Road crossing was accomplished in 2011, the Red Hill Road crossing will be done in 2012.

The completion of the Conner Creek Road site opens 2.5 miles of habitat to adult salmonids and 1,000’ to juveniles. It also established the staging and storage areas to begin and complete the 2nd crossing project early in the 2012 construction season.

This project is unique in that the construction footprint was minimal. No trees were removed for construction and strenuous sediment control efforts were successful. Disturbed areas were treated with local pine and leaf mulch rather than straw.

This project is a coordinated effort by the California Coastal Conservancy, California Dept of Fish & Game, US Forest Service Resource Advisory Committee (RAC), US Forest Service/National Fish and Wildlife Foundation, US Fish and Wildlife Service (USFWS), National Oceanographic and Atmospheric Administration, National Association of Counties, US Bureau of Reclamation-Trinity River Restoration Program, the Trinity County Department of Transportation and LanMark Forestry.
