290 | The number of large scale hydropower or diversion dam partial barriers to fish passage removed at a specified worksite in the estuarine zone. -Large scale hydropower and diversion dams: Large man-made dams that are used for hydropower generation, or water supply management that pose complete or partial barriers to fish 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. -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. 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 | 290 | The number of large scale hydropower or diversion dam partial barriers to fish passage removed at a specified worksite in the estuarine zone. -Large scale hydropower and diversion dams: Large man-made dams that are used for hydropower generation, or water supply management that pose complete or partial barriers to fish passage. -Partial barrier: A barrier to fish migration, preventing passage to specific life history stages.
