From the Abstract: "This report presents results from the third year of a long-term monitoring effort by the Washington State Department of Ecology to measure mercury trends in resident freshwater fish tissue. ... In 2007, 60 individual largemouth bass and 32 composite samples representing eight species were analyzed from Deer Lake, Lake Fazon, Lower Goose Lake, Lake Ozette, Lake Samish, and Lake St. Clair. Water and sediment samples were also collected to evaluate selected parameters that may influence mercury uptake in fish tissues. Seventy-three percent of individuals and 28% of composites sampled exceeded the Environmental Protection Agency's recommended water quality criterion of 300 ppb. A single four-year-old female bass from Lake Ozette contained a mercury concentration of 1800 ppb."
