Gold mining and water quality conditions on public lands of the Yukon and southwest subregions of Alaska

"The primary purposes of this report are: 1) to characterize the setting in which gold mining is occurring in Alaska; 2) report observations at six mining locations or operations; 3) to analyze potential effects of selected mining methods on water quality under various physical conditions; 4) perform a comparative analysis of natural variability in water quality as compared to potential changes due to mineral development; 5) document authorities under which the Bureau of Land Management (BLM) should require surface management changes due to water quality constraints; and 6) recommend a water quality study and program direction for BLM in Alaska"--Leaves 1-2.
