Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
292	The number of small scale push-up or diversion dam partial barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. -Small scale push-up or diversion dam: An earthen push-up dam or small scale concrete diversion dam constructed to divert water for irrigation or hydropower that allows impaired passage. -Partial barrier: A barrier to fish migration, preventing passage to 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 some fish past, 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.	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		292	The number of small scale push-up or diversion dam partial barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. -Small scale push-up or diversion dam: An earthen push-up dam or small scale concrete diversion dam constructed to divert water for irrigation or hydropower that allows impaired passage. -Partial barrier: A barrier to fish migration, preventing passage to specific life history stages.
