This report is intended to be a guidance document for use by the Lake Fork of the Gunnison Watershed Group (LFWG) in prioritizing and planning water quality reclamation projects at Mine sites in Henson Creek above the confluence with the Lake Fork of the Gunnison River. Investigation of the water quality of Henson Creek was initiated as part of the effort to improve the water quality in the Lake Fork of the Gunnison above Lake City. Henson Creek was targeted because previous investigations had shown that Palmetto Gulch was impacted by past mining, resulting in listing on the Clean Water Act 303(d) list of impaired waters for zinc and cadmium. In addition there was visual evidence of impairment in other portions of the Henson Creek Watershed.
