Diablo Lead agency State Coastal Conservancy Lead agency Unknown Unknown 0 The purpose of this project is to remove fish passage barriers along Mitchell Creek as part of a comprehensive effort to return steelhead to the Mt. Diablo Creek watershed, and to restore the riparian ecosystem along Mitchell Creek to improve critical habitat for wildlife, as well as improve water quality. Mitchell Creek and Mt. Diablo Creek, together with Donner Creek, comprise the most pristine watershed remaining in the Concord/Walnut Creek region. They are the focus of a recently formed community watershed group, and potentially home to steelhead trout. The headwaters of Mitchell Creek originate on the north side of MDSP, and contains some creek stretches with healthy riparian habitat, and a number of degraded sections. The creek is severely incised in areas where fill from old road beds and a large earthen dam is perched on the creek banks. These steep fill slopes continually erode and deliver sediment directly into the creek, degrading trout habitat and water quality. This project seeks to restore the natural hydrologic function to Mitchell Creek, thus helping to improve the health of the entire Mt. Diablo Creek watershed. Natural Heritage Institute, Save Mount Diablo, and Environmental and habitat protection and improvement. California State Parks Foundation are all partners for this project.
