Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
284	The number of partial barriers that are addressed by removal of a small scale push-up or diversion dam at a worksite in the freshwater non-tidal zone. -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 the tidal influence of the estuarine zone.	84, 208

84. Remove/Install Diversion	Active	Work that removes, replaces, or avoids creating a fish passage barrier associated with a stream diversion, including push-up dams. May be part of a diversion consolidation effort that reduces the number of diversion sites. Includes installation of alternative ways to divert stream flow without creating passage barriers caused by traditional diversion structures. Examples include, but are not limited to, infiltration galleries, instream diversion pumps, and lay-flat stanchions.	2011		284	The number of partial barriers that are addressed by removal of a small scale push-up or diversion dam at a worksite in the freshwater non-tidal zone. -Partial barrier: A barrier to fish migration, preventing passage to specific life history stages.

208. Irrigation Infrastructure Construction or Replacement	Active	All actions related to the construction and installation of irrigation infrastructure for the purpose of fish and wildlife conservation. Includes fish screens (and related infrastructure such as concrete, gantries, solar panels, bypass pipe, etc.), headgates, flow measuring devices, irrigation diversions, siphons, wells, piping, pumps, and fish passage structures associated with irrigation diversions. The design of complex or large-scale screens is typically 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.	2025		284	The number of partial barriers that are addressed by removal of a small scale push-up or diversion dam at a worksite in the freshwater non-tidal zone. -Partial barrier: A barrier to fish migration, preventing passage to specific life history stages.
