Overview

Yurok and USBR logo

The Yurok Tribe Fisheries Department Design and Technical Services Program was tasked by the United States Bureau of Reclamation Central Valley Project Improvement Act Habitat Restoration Program to conduct a system wide base-line data collection effort across 174 miles on the Sacramento River to develop habitat and decision support modeling. High resolution aerial imagery, topography, bathymetry, and water surface elevations were collected and are intended to support the development of a hydrodynamic model framework for predicting habitat across a range of flows. The model will support measures needed to restore anadromous fish to optimum and sustainable levels in accordance with the restored carrying capacities of Central Valley rivers, streams, and riparian habitats. The data will also be used to support planning, design, and analysis of current and future restoration projects on the Sacramento River.
