The Salt Chuck Mine is an inactive former gold, silver and copper mine located on Prince of Wales Island in the Tongass National Forest at the northern end of Kasaan Bay. Kasaan Bay is host to the Kasaan Tribe (several hundred people) which uses the bay as a commercial and subsistence fishery and shell fishery. Heavy metals from tailings both in the upland and in the bay are impacting water quality and sediments in the bay and Lake Ellen Creek which drains into the bay. These impacts affect salmon and shellfish in areas where both are harvested intensively by the local native community.
