Metric Guidance ID	Description	Used on Work Elements
299	The number of weir full barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. -Weir: A stream-spanning structure used to facilitate or divert passage of salmon across steep grades; or a structure used by fish hatcheries to divert fish passage for collection or removal. -Full barrier: A complete barrier to fish migration, preventing passage for all life history stages. -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 tidal influence.	85

85. Remove/Breach Fish Passage Barrier	Active	Work that facilitates fish passage over a human-made barrier by breaching or removal without replacement. This includes dams, weirs, fish ladders, tidegates, culverts, bridges, and road crossings. If the dam is part of a diversion, use 208. Irrigation Infrastructure Construction or Replacement. If installing a fish passage structure at the same location, use 184. Install Fish Passage Structure, and have removal of the passage barrier as a milestone under that work element.	2011		299	The number of weir full barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. -Weir: A stream-spanning structure used to facilitate or divert passage of salmon across steep grades; or a structure used by fish hatcheries to divert fish passage for collection or removal. -Full barrier: A complete barrier to fish migration, preventing passage for all life history stages. -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 tidal influence.
