This data set characterizes the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande Cutthroat Trout (Oncorhynchus clarkii virginalis) or have been considered potential restoration areas for the fish. The majority of these streams had no previous record of continual temperature records. When compared to Colorado water temperature criteria (Cold Tier 1), a portion of these populations appeared to be at risk from elevated stream temperatures, as indicated by exceedance of both acute and chronic water quality metrics. Summer water temperature profiles recorded at sites within current Rio Grande Cutthroat Trout habitat indicated that although the majority of currently...

This data set summarizes electrofishing effort, observations, and tissue sampling of aquatic vertebrates near Yellow Pine, Idaho. Sampling was conducted using a backpack electrofishing unit at two reference sites including Cane Creek and Sugar Creek, and at three mine impact sites including Sugar Creek and Cinnabar Creek. Juvenile Bull Trout (Salvelinus confluentus) were present at all five sites and were the primary species targeted during our sampling effort. Additional tissue samples of Sculpin, and amphibians were taken when available. Where possible, a two pass (quantitative depletion) electrofishing survey was conducted at each site for non-USGS stakeholders (Nez Perce Tribe and Idaho Department of Fish and...
