Fisheries & Aquatic Habitat Assessments
ECORP’
s fisheries and aquatic staff review, design, and conduct environmental assessment studies in all of California’
s aquatic habitats, including riverine, lacustrine, estuarine, and marine systems. We conduct technical studies and prepare supporting documentation for Biological Assessments and Section 7 consultations for salmonids [National Marine Fisheries Service (NMFS)] and non-salmonids [U.S. Fish and Wildlife Service (USFWS)] under the Endangered Species Act. ECORP biologists are proficient with hydroacoustic assessments, acoustic tagging, and mobile tracking methodologies.
ECORP biologists hold federal incidental take permits for numerous federally-listed species in California, including the various races and Evolutionarily Significant Units (ESUs) of Chinook salmon and steelhead, tidewater goby, Santa Ana sucker, and unarmored threespine stickleback. Our biologists work with hydraulic engineers to evaluate existing and predictive fish habitat (PHABSIM modeling), affects to fish and habitat from altered streamflows (dam and bypass releases), fish passage, fish screening, and fish entrainment. ECORP conducts field-level stream and riparian habitat mapping using USFWS protocols, and channel classification using the Rosgen multi-level approach.
