Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch), extensively utilize small stream habitats influenced by a changing urban landscape. This study used a comprehensive fish health assessment concurrent with the U.S. Geological Survey’s Pacific Northwest Stream Quality Assessment in 2015 to quantifiy impacts from disease in juvenile coho and cutthroat salmon, impacts to...

The dataset includes four seperate files of data for a project that examined the strontium isotopic composition of otoliths of Clear Lake Hitch. Otoliths examined in this study were from randomly-sampled individual Clear Lake Hitch that recruited into the adult population in Clear Lake. The fish were collected in June and July 2017. Strontium isotopic composition (87Sr/86Sr ) in otoliths was determined with a multicollector LA-ICP mass spectrometer (LA-ICMPS; Nu Plasma HR, Nu Instrument, Inc.) interfaced with a Nd : YAG 213-nm laser (New Wave Research UP213) at the University of California, Davis. Fish capture and size data are in the file Clear Lake Hitch Otolith Data_FISH. Otolith increment data are in the file...
