Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
341	Enter the number of bridges installed to improve fish passage at a specified worksite. (Based on WE guidance this should typically be 1 structure per WE.) -Bridge: Installation, improvement/upgrade or replacement of a bridge over a stream to provide/improve salmonid passage under a road. The bridge allows for passage underneath with a semi-natural stream bed. -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.	184

184. Install Fish Passage Structure	Active	Install, replace, or modify structures when the intent is to improve fish passage and/or flow, typically by removing or modifying a full or partial instream barrier. "Structures" include fish ladders, bridges, culverts, jump pools, roughened channels, and weirs. "Barriers" include such obstacles to fish passage as tidegates, weirs, culverts, rock fords, road crossings, and manmade dams. Structures also include natural barriers such as logjams and natural streambeds. This work element excludes diversion dams. Use 208. Irrigation Infrastructure Construction or Replacement for diversion dam removal, and include this work as a milestone under this WE. Where anadromous fish are present, structures installed must meet current NOAA specifications and USFWS specifications for lamprey and bull trout respectively. Use 180. Enhance Floodplain/Remove, Modify, Breach Dike if the installation of a passage structure is associated with a dike removal, breaching, and modification, and may create additional acres of habitat as well as providing access to instream habitat. Use 70. Install Fish Monitoring Equipment, for weirs installed primarily to restrict fish passage for the purpose of monitoring or collecting fish (e.g., picket weirs). Design of complex or large-scale fish passage structures is often a separate work element (see 175. Produce Design). In known or potential lamprey habitat use guidance from these documents: Guidelines to Minimize Impacts and Maximize Benefits for Native Lamprey During In-water Work https://www.fws.gov/pacificlamprey/BPALampreyGuidanceDocuments.cfm Pacific Lamprey Habitat Restoration Guide https://www.fws.gov/pacificlamprey/BPALampreyGuidanceDocuments.cfm. Lamprey presence can be determined from Data Basin map https://www.fws.gov/pacificlamprey/BPALampreyGuidanceDocuments.cfm. This map does not show all distribution due to limited data. Pre-project lamprey surveys should be done (see USFWS lamprey Guidelines document) if the map does not show presence.	2011		341	Enter the number of bridges installed to improve fish passage at a specified worksite.
