Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
184	Length of treatment in miles. This should be the total length of the stream to be treated with gravel placement (if placement of gravel is dumped with the expectation of distribution from high flows, identify the length of stream expected to be treated). The addition of gravel, sand and fine sediments into the stream with size ratios to support salmonid spawning and rearing.	29, 30

29. Increase Aquatic and/or Floodplain Complexity	Active	This work element is intended for the placement of natural materials in the water or on the floodplain to create habitat features or improve channel morphology. Actions include placement of large woody debris (LWD), constructed riffle features, boulder placements, and beaver dam analogs (BDAs). It also includes placing gravel to improve complexity by creating pools or fish spawning habitat. Complexity structures are typically used in stream reaches with limited natural tendencies to foster development of, or ability to maintain, natural habitat features. For example, structures are often placed to improve habitat variability for fish in otherwise uniform flow conditions. These actions can have the objectives of creating and/or maintaining scour pools, influencing channel sinuosity and hydraulic complexity, recruiting and retaining wood and gravel, sorting of gravels, and supporting hydrologic connectivity with the floodplain. Design review should be at 80% completion before contracting to help assure implementation and expenditure of contracted funds. When this WE is used, the contract must also include 175. Produce Design . If structures are being added to resolve a fish passage barrier, use 184. Install Fish Passage Structure . If maintaining an existing structure, use 186. Operate and Maintain Habitat/Passage/Structure . If work involves only plantings, use 47. Plant Vegetation . If other methods are used to control erosion in the riparian and upland zones, use 55. Erosion and Sedimentation Control . This work element should not be used for bank stabilization unless it is part of a larger habitat or complexity action.	2011		184	Length of treatment in miles. This should be the total length of the stream to be treated with gravel placement (if placement of gravel is dumped with the expectation of distribution from high flows, identify the length of stream expected to be treated). The addition of gravel, sand and fine sediments into the stream with size ratios to support salmonid spawning and rearing.	Optional	Yes	Yes	No
ITS Action Category: Stream/Habitat Complexity ITS Metric: LWD/boulder/rock weir placement
30. Realign, Connect, and/or Create Channel	Expired	This work element is intended for adding sinuosity, meanders, side channels, and/or off-channel habitats (e.g., sloughs or oxbows). Actions include reconnection of historical channels, excavation of new channels, or actions that significantly alter channel planform, profile, and cross-section. Channel modifications should create diverse habitats (pools, riffles, glides and runs) while retaining characteristic features and forms over time. These actions should increase stream channel and/or side channel length and acreage. This WE may be the main emphasis of an aquatic habitat restoration project, or part of a larger habitat project. Design review should be at 80% completion before contracting to help assure implementation and expenditure of contracted funds. When this WE is used, the contract must also include 175. Produce Design . If work is solely to add structures/features within the existing channel, then use 29. Increase Aquatic and/or Floodplain Complexity . If structures are being added to resolve a fish passage barrier, use 184. Install Fish Passage Structure . If work is to create, restore, or enhance wetland function then use 181.
