296 | The number of natural dam partial barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. -Natural dam or barrier: Naturally created barriers to fish passage either in the form of log jams or stream aggradation resulting in subsurface flows from landslides or low flows. -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 tidal influence. |

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 | 296 | The number of natural dam partial barriers to fish passage removed at a specified worksite in the freshwater non-tidal zone. -Natural dam or barrier: Naturally created barriers to fish passage either in the form of log jams or stream aggradation resulting in subsurface flows from landslides or low flows. -Partial barrier: A barrier to fish migration, preventing passage to specific life history stages.
