Description In 2010, Ecology looked for differences in contaminant levels in fish since 2003 at Lake Chelan (DDTs), Wenatchee River (PCBs), and Banks Lake (dioxins/furans). Levels of PBTs were characterized in fish from Lake Wenatchee, Potholes Reservoir, and Lake Ozette (sockeye salmon). Two sample preparation methods were compared (skin-on versus skin-off fillets).

No reductions in contaminant levels were found in Lake Chelan or Wenatchee River fish. The Fish Consumption Advisories for these waters are unlikely to be changed. Fish from Banks Lake had lower levels of PBTs than in 2003. Results from skin-off and skin-on fillets showed no difference.
