Metric Guidance ID	Description	Used on Work Elements
271	The number of mine tailing partial barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. (Note: If distance between barriers is greater than half a mile use two WE.) -Partial barrier: A barrier to fish migration, preventing passage of specific life history stages. These barriers may be temporal in nature or limit passage due to obstructions, e.g., high flow, low flow, temperature, physical barriers, etc., or other variables that may allow passage for some species, but not others. - Freshwater non-tidal: Habitat with freshwater flowing in a channel or watercourse, including lakes, ponds, and adjacent areas below the high water mark that is not subject to the tidal influence of the estuarine zone.	52

52. Remove Mine Tailings	Active	Work to remove or re-contour remnant landscape effects from old mining operations. Could be terrestrial or aquatic in nature. If work also creates wetland or modifies channel use 181. Create, Restore, and/or Enhance Wetland and 30. Realign, Connect, and/or Create Channel.	2011		271	The number of mine tailing partial barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone.
