First entered into YRITWC database in 2006. The site was used as a recreation site for swimming and fishing. Big Lake was used as a dumping ground for 20 years or more. A sawmill was located there in the 1960s and when it broke down it was shoved into the lake. Refuse is estimated to include vehicles, motors, batteries, and general household garbage. A shop building located north of the lake (City Shop)(see attached photo) has fuel and hazardous substances and a "distinctive diesel smell." The community is concerned that the contamination in the lake could damage their subsistence fishing resources and water quality of surrounding sloughs and rivers.
