Lower Clear Creek Floodway Rehabilitation Project

Project Description: The Lower Clear Creek Floodway project was designed as a four phase project, that was to rehabilitate the natural form and function of the 1.8 mile channel and flood plain along the Lower Clear Creek., in Shasta County. This includes increasing the vegetation along the creek, increasing the quantity and quality of salmon and animal habitat, and creating a working system for all concerned. To achieve these goals, the project has reconstructed selected areas of the Lower Clear Creek channel, improved fish passage, spawning and rearing habitat, planted vegetation and created off-channel wetlands for waterfowl and animals alike. Clear Creek is a hikers, anglers and bird watchers paradise. The creek meanders along Clear Creek Road and is filled with wild life, from songbirds and migrating waterfowl to beaver, deer, black bear and mountain lion. The creek again teems with salmon, steelhead and trout.

Gemorphology

WY2006 Geomorphic Monitoring Annual Report

June 2007, 5.73 MB, PDF

This report provides the findings from the fourth year of geomorphic monitoring on lower Clear Creek. The first three years of data collection focused on project-scale monitoring of the Lower Clear Creek Floodway Rehabilitation Project, while WY2006 encompasses a broader, basinwide perspective which facilitates watershed-scale geomorphic investigations. The overall objective of geomorphic monitoring at both scales is to better understand how the synthesis of dam removal, gravel injection, channel/floodplain modification, stream-flow and sediment transport influences project-scale and basin-wide restoration goals. Much of the data collected for (1) the 2006 Update to the Clear Creek Gravel Management Plan (GMA 2006), (2) WY2003-2005 Geomorphic Monitoring reports, and (3) various gravel injection design documents, are highly relevant to basin-wide investigations and will be referred to frequently. The WY2006-2008 Geomorphic Monitoring Annual Reports are intended to be read-able and concise, with most of the supporting data contained in appendices and a 2008 synthesis-report relating WY2003-2008 geomorphic monitoring. Further, much of the data collected for this project were presented in the 2006 Update to the Clear Creek Gravel Management Plan and will be summarized here.

Juvenile Chinook Habitat Use in Lower Clear Creek, 2003
October 2004, 7.3 MB, PDF
The Lower Clear Creek Floodway Rehabilitation Project involves the phased reconstruction of the floodplain and stream channel of approximately 2 miles of Clear Creek, Shasta County, CA. Phase 3A relocated and reconstructed a 1,400 ft section of stream channel and was completed in September 2002. Phase 3A was the first project phase involving the relocation and reconstruction of the stream channel. The objective of the 2003 Habitat Use study was to determine if channel reconstruction changed habitat use by juvenile Chinook salmon Oncorhynchus tshawytscha. The study compared juvenile Chinook densities in the newly constructed stream channel to densities in two control reaches immediately upstream and downstream of the project boundaries. Chinook densities were determined by underwater observations within the three study reaches. We completed seven habitat use surveys between February 26 and April 17, 2003.
