Abstract The report contains a compilation and interpretation of the historical records of water quality and discharge for the period 1940-91 from the two most significant discharge points for acid mine drainage at Iron Mountain, Shasta County, California--the Richmond and Lawson portals. The primary objectives are (1) to clarify whether or not there is a hydrologic connection between the Richmond and Lawson Tunnels, and (2) to formulate a conceptual model of subsurface processes that accounts for water-quality and discharge trends with time.
