Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
349	Enter the number of natural stream crossings (road crossing removal) installed to improve fish passage at a specified worksite. (Based on WE guidance this should typically be 1 structure per WE.) -Road crossing removal: Removal of stream road crossing and the affiliated road structures so that the stream flows unimpeded with a natural stream bed. -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.	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		349	Enter the number of natural stream crossings (road crossing removal) installed to improve fish passage at a specified worksite.
