Habitat Work ScheduleThe Habitat Work Schedule (HWS) is a project mapping and tracking database for Washington State’s Salmon Recovery Lead Entities and their partners. The HWS system brings together Lead Entity habitat projects in one place. It enables natural resource professionals, project funders, and the public to follow past, current, and proposed projects from concept through implementation and then, once complete, into the monitoring phases. This leaves a legacy of local and statewide salmon recovery efforts and creates a better coordinated salmon recovery effort.

Information Required for Conceptual Projects

  • Project Name
  • Project Description
  • Proposed Start and End Dates
  • Category / Activity:  Restoration, Acquisition, Combined
  • Project Contact Person:  Name, Address, Phone, email
  • Project Location
  • Download the Conceptual Project Form

Conceptual status represents a range of projects from ideas to fully scoped projects.  This category is appropriate for projects that are not ready for “proposed” status, i.e., no project sponsor, lack of community support, insufficient project information, not ready to be implemented, etc.  The purpose of this category is to capture project ideas, some of which may turn into funded projects and some of which may never actually mature to be fundable projects.  Expanding the Habitat Work Schedule to Include Conceptual Projects (3-year-list)

To submit a conceptual project, please complete the attached form and send  to Kirsten Harma, MSc. Watershed Coordinator/Lead Entity Coordinator Chehalis Basin Partnership & Grays Harbor/Chehalis Basin Lead Entity E-mail: - (360) 488-3232.

The Chehalis Basin Lead Entity will continue to collect conceptual projects as a proactive step towards strategically directing habitat restoration and protection within the Chehalis Basin. A conceptual project may range in scope from a broad idea to one that is ready to implement.  Projects are “conceptual” because they may not be fully ready for implementation.  The reasons may vary, but typically, it is because a project lacks a sponsor, community buy-in or support, or enough information to move forward.  For further information please see the report.

Fish Passage

Physical Process Effects

Poor fish passage conditions are typically a result of improperly sized water crossing structures.   Undersized stream crossing structures do not allow for adequate transport of substrate, LWD, or fish.  In many cases the area immediately upstream of undersized crossing structures accumulates sediment and LWD and the area immediately downstream is scoured.  These symptoms are a direct result of altered stream flow in the specific location of the crossing. Chenois Creek before correction

Effects on Fish

Undersized stream crossing structures restrict salmon access to upstream habitat for spawning and rearing. The inability for fish to access upstream habitat reduces the system’s productivity (carrying capacity and nutrient cycling).   The inadequate transport of substrate and LWD through stream crossing structures can decrease habitat characteristics needed for salmonid survival.  Some examples are:

-- LWD for cover

-- Substrate for spawning

-- Scour downstream channel





Physical Process Effects

Floodplain impacts typically are a result of floodplain filling, dike and levee construction, and streambank armoring.   Floodplain impacts such as dikes and levees reduces the amount of food water storage capacity, which concentrates the flow and its energy to a more confined area.  This concentration of flow and energy contributes to scour, channel incision, and streambank erosion. 

Example of Floodplain

Effects on Fish

The installation of dikes and levees reduces the amount of accessible off-channel habitat for juvenile salmonid rearing.  The installation of dikes and levees also reduces the amount of water storage in a system.  This water storage is critical for adequate stream flows, for salmonids, during the summer months when less precipitation occurs. 

Large Wood (LWD)Engineered Wood Placement

Physical Process Effects

LWD deficiencies are usually the result of poor riparian conditions and removal of LWD from the channel.   Insufficient amount of LWD does not allow for adequate substrate retention and gravel sorting and can contribute to channel scour and incision.   Low levels of LWD do not provide instream channel complexity (cover, pools, and riffles).   Low levels of LWD do not supply associated nutrients.

Effects on Fish

Low levels of LWD do not provide instream channel complexity needed to create the various habitat attributes for the various life stages of salmonids (cover, pools, riffles).   Cover for protection Sort substrate for more ideal spawning conditions Create holding areas for adult and juvenile salmonids   Low levels of LWD limits the amount of nutrient input into a system indirectly needed for salmonid survival.

Riparian Riparian Example, Mills Creek


Physical Process Effects

Poor riparian conditions are typically the result from intentional removal of vegetation.  This is usually associated with land use conversion or active timber harvest management.   Lack of riparian cover contributes to increased water temperatures.  Increased water temperature decreases the amount of dissolved oxygen the water can hold.   An insufficient riparian corridor does not adequately filter surface water runoff which can allow sediment and pollutants to enter the stream/river.   An inadequate riparian corridor, such as hardwood dominant or void of vegetation, does not provide adequate long term LWD recruitment (see LWD section below).

Effects on Fish

The installation of dikes and levees reduces the amount of accessible off-channel habitat for juvenile salmonid rearing.    The installation of dikes and levees also reduces the amount of water storage in a system.  This water storage is critical for adequate stream flows, for salmonids, during the summer months when less precipitation occurs.


Sediment examplePhysical Process Effects

High contributions of sediment are typically associated with land use management practices. Common sources are usually logging roads, landscapes void of vegetation, landslides, and areas of excessive streambank erosion.   High amounts of sediment can cause excessive aggradation downstream and alter substrate composition.

Effects on Fish

High amounts of fine sediment can suffocate salmonid eggs laid in the gravel substrate.   Increased sedimentation can change invertebrate assemblages, which juvenile salmonids prey upon. Excessive sedimentation can cause accelerated instream aggradation resulting in altered physical habitat features such as: filling of pools and rearing areas.  Excessive sedimentation can alter the substrate composition to a less suitable quality for salmonid spawning.

Water Quality

Physical Process Effects

Poor water quality is typically associated with water temperature, suspended solids, and chemical composition.  Impacts usually result from poor riparian conditions and stormwater runoff problems.

Effects on Fish

High amounts of sediment can suffocate salmonid eggs laid in the gravel substrate, which reduces egg survival.  Increased water temperatures can cause a physical stress on salmonids jeopardizing their survival.   Low summer flows concentrate instream toxins that can adversely affect salmonids.

Water Quantity

Example of low waterPhysical Process Effects

Low summer flows are typically a result of an altered hydrology (landscape manipulation that allows rapid surface runoff).  In non-glacial systems summer flows are maintained by groundwater connectivity, wetland discharges, and precipitation.   The combination of altered hydrology and the removal of instream structure contribute to channel incision and disconnection from floodplains and adjacent wetlands which results in the inability to store water for summer flows.  High peak flows also contribute to accelerated bank erosion and movement of substrate downstream.   Low summer flows are susceptible to becoming too warm, low in dissolved oxygen, and have a higher concentration of other pollutants, all of which affect salmonid survival.

Effects on Fish

Low flows tend to have higher temperatures that decrease its ability to hold dissolved oxygen.  High water temperatures and low dissolved oxygen impose physical stress on salmonids.   Low flows can inhibit upstream salmonid migration and reduce the amount of available instream habitat for rearing.
