Ghost Lake was placed on the impaired list in 1998 due to mercury concentrations in fish tissue from atmospheric deposition. Ghost was assessed for the 2012 listing cycle and the original listing due to mercury levels in fish tissue was confirmed. Phosphorus and algae were evaluated in 2014 and found to be in good condition. Aquatic plant communities of Ghost Lake were evaluated in the 2022 cycle and data indicated a healthy system.
