Salmon spawning locations (redds) in two restored reaches of the lower Merced River, California

Metadata Updated: October 29, 2023

Salmon spawning locations (redds) were mapped to characterize habitat use along two reaches of the lower Merced River in California's Central Valley and thus support research intended to evaluate the extent to which large-scale restoration projects provided improved salmon spawning habitat. A related goal of this study was to improve our understanding of the geomorphic factors influencing spawning site selection by salmon. Salmon redds were mapped during the fall of 2016 at the Merced River Ranch and Robinson Reach field sites using real-time kinematic (RTK) GPS. The location of the center of each redd was surveyed in the UTM Zone 10/NAD83 coordinate system, with easting and northing coordinates recorded in units of meters.
