The ranking of the individual sites is given in Table 1 above. These sites are considered the highest priorities for reclamation. In addition, there are two draining mine adits where hydrologic controls should be beneficial, and may stop all drainage. Each of these sites will be discussed in detail below. In general, the sites that received a ranking of 1 are near or in a stream channel, and exhibit the greatest amount of historic erosion.
