To assess the effects of rotenone (fish toxicant) treatment and possible fish removal effects on nesting Osprey (Pandion haliaetus) populations, nests were observed at two reservoirs east of Ashland, Oregon. Hyatt Reservoir was treated with rotenone on October 12, 1989. Howard Prairie was observed as an untreated reference area. Nests at both reservoirs were observed two years pre-treatment (1988, 1989) and two years post-treatment (1990, 1992). The dataset contains Osprey reproductive parameters, foraging parameters, prey delivery rates and bald eagle piracy rates at eight intensively observed nests. Fish stocking records and creel data were obtained from the Oregon Department of Fish & Wildlife for both reservoirs...

The persistence and degree of mercury contamination of the lower Carson River system (LCRS) have led to placement of a portion of the Carson River Basin (including Lahontan Reservoir) on the US. Environmental Protection Agency (EPA) National Priorities List ("Superfund") for research and cleanup. The potential toxicity of mercury concentrations within the LCRS to piscivorous birds (snowy egrets, black-crowned night-herons, and double-crested cormorants) was examined from 1997-2006.
