Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
302	The number of culvert partial barriers to fish passage removed at a specified worksite in the estuarine zone. -Culvert: Conduit used to enclose a flowing body of water. It may be used to allow water to pass underneath a road, railway, or embankment for example. Culverts can be made of many different materials; steel, polyvinyl chloride (PVC) and concrete are the most common. -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. -Estuarine: Habitat that is part of a semi-enclosed coastal body of water that is subject to the ebb and flow of tides, with one or more rivers or streams flowing into it, and with a free connection to the nearshore marine zone. This includes habitat impacted by the highest high and lowest low tides of a year. Estuaries are environments whose pH, salinity, and water levels are subject to the ebb and flow of tides, and the physical and chemical properties of the river that feeds the estuary and the ocean from which it derives its salinity. This habitat includes floodplain/riparian habitat subject to inundation from the tides.	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		302	The number of culvert partial barriers to fish passage removed at a specified worksite in the estuarine zone. -Culvert: Conduit used to enclose a flowing body of water.
