To check their catch, researchers must pull the net and its contents from the water. But this additional handling can harm and even kill the same fish that wildlife agencies are trying to save with the support of robust, long-running monitoring efforts.

Such practices also hasten the destruction of an important and dwindling habitat. Melissa Rohde of the State University of New York College of Environmental Science and Forestry (SUNY-ESF) and colleagues analyzed five years of high-resolution satellite and water resource data showing vegetation greenness along California rivers. Trees growing alongside the 30 percent of state rivers with natural flows decreased in greenness from the wet spring through the dry summer months, the scientists report in the Proceedings of the National Academy...Read More
A few months before his retirement in October 2021, Ariel Rubissow Okamoto asked Ted Sommer, lead scientist for the California Department of Water Resources, to reflect on his accomplishments and hopes for the future. Sommer is a leading researcher on native fishes, and has published more than 60 research articles in peer-reviewed scientific publications since 2001. Sommer began his long career at DWR in 1991 under Dr. Randy Brown. Early on he founded the Feather River fish monitoring program, but his...Read More
