1 INTRODUCTION As the second largest river system in the State of Washington outside the Columbia River basin, the Chehalis River supports numerous species and runs of salmonids. Current conditions in the watershed limit fisheries production. Limiting factors for salmonids include fish passage blockages (e.g., impassable culverts), floodplain conditions (e.g., incised channels or drainage and filling of wetlands), streambed substrate (e.g., mass wasting or low large woody debris levels), riparian conditions (e.g., tree canopy loss), water quality (e.g., high water temperature or low dissolved oxygen), and water quantity (e.g., low summer base flows) in the Chehalis River basin (Smith and Wegner 2001).

In order to support salmonid enhancement planning in the Chehalis River basin, the Chehalis River Basin Flood Authority (Flood Authority) contracted with Anchor QEA, LLC, to develop a Comprehensive Salmonid Habitat Enhancement Plan that identifies potential opportunities to improve habitat conditions. This work is being completed in two steps: 1. Development of a comprehensive list of opportunities based on compilation from

other sources and the identification of additional opportunities, particularly side channels.

2. Prioritization of identified opportunities to help inform which opportunities provide

the greatest benefits to meet the habitat needs of the watershed. This report describes the step 1 identification of enhancement opportunities. The objective of this report is to list and summarize enhancement opportunities including existing and potential offchannel habitat along the upper mainstem Chehalis River (river miles [RMs] 33 to 118) and associated tributaries (Water Resource Inventory Area [WRIA] 23).

1.1

Study Area

The Chehalis River basin encompasses 2,520 square miles and drains 2,660 square miles flowing through the Cascade, Puget Lowland, and Coast Range ecoregions and emptying into Grays Harbor near Aberdeen (Omernik 1987). It is divided into the Lower Chehalis Basin (WRIA 22) and the Upper Chehalis Basin (WRIA 23); this assessment is focused on WRIA 23. Within WRIA 23, the watershed was divided into six management units (subbasins) representing the major watersheds (Figure 1):

Black Management Unit (includes Black River and Porter Creek subbasins) Boistfort Management Unit (Upper Chehalis, South Fork Chehalis, Stillman Creek, and Lake Creek) Chehalis Mainstem Management Unit Lincoln Management Unit (Lincoln Creek, Independence Creek, Garrard Creek, Gaddis Creek, Rock/Williams Creek, Bunker Creek, Scammon Creek, Mill Creek, and Stearns Creek) Newaukum Management Unit (Newaukum mainstem, North Fork Newaukum, Middle Fork Newaukum, Salzer Creek, Coal Creek, Dillenbaugh Creek, Berwick Creek, and China Creek) Skookumchuck Management Unit (Skookumchuck River and Scatter Creek)

Management units were delineated based on Watershed Administrative Units (WAUs) from the Washington Department of Natural Resources (DNR). These WAUs did not match exactly with the watershed boundaries in the Work Plan; however, they looked more accurate, so these more recent WAUs were used in this analysis. With this decision, the DNR WAUs were grouped into management units that closely approximate those described in the Work Plan.

Phone interviews and meetings also were conducted with local planners and biologists to obtain the most recent list of potential projects throughout WRIA 23. A workshop was convened on October 19, 2011, to bring together Chehalis River Basin biologists and planners to discuss potential enhancement projects and prioritization methods.

Approximately 20 people representing various entities within the watershed participated and offered insight into potential projects and identified projects already completed or in progress (Attachment A). The projects listed in this report reflect the input from this workshop.

Data Sources and Evaluation

LIDAR and aerial photography were used to identify areas with potential for restoration in the mainstem Chehalis, South Fork Chehalis River, and Skookumchuck River. No LIDAR data are available for the Newaukum River.

Existing geographic information system (GIS) layers of fish habitat and limiting factors, including existing culverts, were used to make maps of project locations. The side channel GIS layer was created based on this assessment. Data sources for the layers included: • • •

2.1

LiDAR – Puget Sound LiDAR Consortium, 2002 Aerial – U.S. Department of Agriculture (USDA), National Agriculture Imagery Program, 2009 WAUs – DNR, 2006

Identification of Potential Projects

Potential projects were identified based on an assessment of the common limiting factors within WRIA 23. Seven limiting factors have been identified that have impacts on both physical processes within the watershed and salmonids (Grays Harbor County Lead Entity Habitat Work Group 2011): •

•

•

• •

•

Fish Passage Conditions: Poor fish passage conditions typically result from improperly sized water crossing structures and result in loss of access to spawning and rearing habitat.

Floodplain Conditions: Degraded floodplain conditions typically result from floodplain filling, dike and levee construction, and streambank armoring and result in loss of backwater and side channels used for spawning, rearing, and refugia during high flows.

Riparian Conditions: Poor riparian conditions typically result from intentional removal of vegetation, usually associated with land use conversion or timber harvest, and results in limiting shade, nutrients, and large woody debris availability.

Large Woody Debris: Lack of large woody debris usually results from poor riparian conditions and removal of woody debris from the channel.

Water Quality: Poor water quality typically is associated with water temperature, suspended solids, and chemical composition usually resulting from poor riparian conditions and stormwater runoff problems.

Water Quantity: Low summer flows typically result from altered hydrology (landscape changes that allows rapid surface runoff).

Data Sources and Evaluation

•

Streambed Sediment: High contributions of sediment typically are associated with land use management practices including logging roads, landscapes without vegetation, and areas of excessive streambank erosion resulting in filling in of pools and spawning gravels.

Consideration was given for enhancement projects that would be the most beneficial in terms of response time, probability of success, and duration of the action. Reconnection of isolated habitats has been suggested as a first priority (Roni et al. 2002). In addition, the Habitat Work Group has indicated that replacing culverts to improve fish passage and access to additional habitat, riparian revegetation, and restoring floodplain functions are a priority (Grays Harbor County Lead Entity 2011). However, riparian conditions and large woody debris also are of concern within WRIA 23, and projects necessary to enhance these factors were identified as well. The other three limiting factors also may be addressed as part of enhancements in any of the first four. For example, improvement in riparian conditions will also reduce the amount of sediment that can be deposited into streams within the watershed and will provide additional vegetative cover, thereby improving water quality by reducing stream temperatures. Based on this, the primary focus for assessment was on four limiting factors: floodplain conditions, riparian conditions, large woody debris, and fish passage conditions. The WRIA 22-23 Habitat Work Group has developed a prioritization strategy based on the general features of each subbasin, type and status of anadromous fish stocks, land use activities, and limiting factor analysis. This strategy prioritized the degree of impact created by each limiting factor on the fitness and survival of targeted stocks by assigning a ranking into three tiers. Tier 1 concerns represent the most pressing limiting factors impacting the targeted stocks and projects targeting these areas will likely provide the greatest benefit to fish. The subbasins with a Tier 1 concern for any of these limiting factors were identified to develop a master list of potential projects. Projects that also addressed other limiting factors were included in the assessment if information was readily available.

A summary of the tiered concerns for each limiting factor separated by management unit was compiled to begin development of the potential project list (Table 1). Tier 1 concerns for floodplain conditions, riparian conditions, and fish passage conditions were used to identify subbasins for targeted projects. In addition, fish use within each subbasin was summarized for integration into the prioritization process (Table 2).

Data Sources and Evaluation

A master list of potential projects was developed for WRIA 23 (Table 3). Projects are listed by management unit and the major tributary identified. The type of enhancement and limiting factor addressed are provided, with multiple limiting factors addressed for some projects. In addition, a general description of the project and potential area of upstream habitat available are provided. For each potential project identified as part of this task, each limiting factor that may be addressed was identified (see Table 3).

Projects previously identified by others are included if they have not been completed yet.

Eighty-nine potential programs or specific projects have been identified within WRIA 23 with 6 identified to enhance floodplain conditions, 27 for fish passage conditions, 7 for riparian conditions, 48 addressing multiple limiting factors, and 1 unidentified (Table 3).

Barriers within the basin were identified based on several efforts. The Mason Conservation District (MCD) identified 2,677 barriers within the Chehalis basin (MCD 2010; yellow, orange, and red dots on Figures 2 through 6). Sites were identified based on the inventory data available to date; no additional field surveys were conducted. As part of that effort, the sites were ranked according to the number of species that may utilize upstream habitat, the amount of habitat upstream of the barrier, and the percent passability of the barrier. The rankings were then converted to percentiles to assign barriers to three tiers, the top 25 percent of sites were included in Tier 1 (top priority), sites in the 50th to 74th percentile were included in Tier 2, and the remaining sites (0 to 49th percentile) were assigned to Tier 3. The sites in Tier 1 represent sites with the most available upstream habitat and species utilization.

A minimum of 10 projects composed of 23 barriers were identified from the list for further assessment and development. Of these, 6 have been corrected, 4 were targeted for correction in 2011, 5 are awaiting approval, and the remaining 8 are awaiting identification of a funding source (MCD 2010). Table 4 provides a complete list of barriers that were ranked as Tier 1 in WRIA 23 and are still in need of funding for removal. LCCD has updated the MCD barrier database with numerous additional barriers where habitat data were physically collected from each barrier (LCCD 2006 and 2007; included on Figures 2 through 6 as purple circles).

The top 99 culverts identified by LCCD are included in Table 5 (30 of these are also found in the MCD data table).

Data Sources and Evaluation

Specific floodplain and riparian project locations are located on relative elevation maps (Figures 7 through 12). Several of these projects came from the Draft Twin Cities Flood Reduction Project, Mitigation Site Evaluations Appendix A (U.S. Army Corps of Engineers 2011). These projects have detailed plans associated with them. Based on the relative elevation maps and analysis of aerial photographs, additional areas in the mainstem Chehalis, Skookumchuck, and South Fork Chehalis have been identified for potential restoration of floodplain, off channel, and side channel habitats. Additional information is needed to understand current land uses and ownership within these areas to determine if restoration of these habitats is feasible.

3 DISCUSSION This assessment identified potential restoration projects within WRIA 23 that would provide additional habitat for the various salmonid species found within the watershed. Projects primarily focused on those that addressed four of seven limiting factors identified as limiting salmonid production, fish passage conditions, floodplain conditions, riparian conditions, and large woody debris. Salmonids rely on habitats, many located above barriers that may be passable, partially passable, or impassable, as well as areas of refuge typically located within the floodplain. Based on the Tier 1 ranked culverts, approximately 2,400 miles of habitat is inaccessible or has limited accessibility for salmonids due to barriers. The majority of projects identified focused on fish passage due to the intensive culvert surveys that have been conducted by both the Chehalis County Conservation District and MCD and several projects were identified that related to other limiting factors as indicated on Table 3; future projects may need to consider other limiting factors, as well as those that are the focus of this report.

During the workshop, several attendees identified the need for preservation of areas that already contain suitable habitat and support the various salmonid species. This is an important consideration since preserving existing habitats may be more cost effective than restoring degraded areas. The documents reviewed during this assessment did not explicitly identify areas in need of preservation, but following a similar methodology of assessing the limiting factors and identifying areas most likely to contain these features would be a first step to identify areas to protect. One example discussed during the workshop was the coldwater areas within the Black River that currently provide summer refuge for salmonids.

It was suggested that these, and similar areas, be preserved. Additional areas may be identified by evaluating areas of groundwater upwelling based on the Department of Ecology report on hydrology in the Chehalis basin (Stanley et al. 2010).

The integration of limiting factors, fish use, and habitat availability is important for assessing subbasins or reaches within the watershed that would provide the greatest gain for cost.

Since funding availability will limit the number and timing of projects that can be completed, it is important to identify and then rank projects properly. A recent study was conducted to help the Flood Authority evaluate future flood protection investments (Earth Economics 2010). As part of that study, the annual value of ecosystem services within the basin was estimated between $1.3 and $11.6 billion.

Discussion

identified a combination of natural capital (e.g., floodplains), selective built capital (e.g., dams and levees), and social capital (e.g., early warning systems and training) as the best investments to achieve flood protection (Earth Economics 2010).

Development of a strategy for conservation, restoration, and development can be accomplished following the framework of the Chehalis Basin Watershed Assessment (Stanley et al. 2010). Utilizing information in that document also may help in developing the prioritization of projects identified in this report. Both impairments and level of importance for several water processes (groundwater recharge, groundwater discharge, and surface water delivery) were identified within subbasins in the Chehalis basin. The incorporation of the assessments was used to establish an overall management framework of areas that would benefit most from protection or restoration. Evaluation of these areas may allow for identification of areas most important for preservation.

The focus on the next phase of this effort is to rank the projects identified in this report. Part of this process will include combining the MCD and LCCD culverts list into one comprehensive database and reassessing the tier assignments based on this larger dataset following the methods of MCD (MCD 2010).

Albert-Dempsey Creek Tributary R7

Correct barrier culvert

Fish Passage Conditions

The Albert fish barrier is on a tributary to Dempsey Creek; Black River; Chehalis River. There are no known barriers up or downstream.

Correction of this barrier would open about 0.15 miles of habitat for coho, cutthroat and possibly PRISM - proposed projects steelhead.

BL-3

Baker-Goliath Creek R9

Correct barrier culvert

Fish Passage Conditions

This 33% passable culvert is on a tributary to Mima Creek which flows into the Black River in Thurston County. There is one private total barrier on an upstream tributary and two partial barriers and one total barrier upstream on DNR land.

Correction of this fish barrier would improve access to 3.91 miles of fish habitat. No downstream barriers.

This culvert is on Davis Creek, a tributary to the Chehalis River. The downstream third of the culvert slopes upward severely which likely caused the invert to rust out. The road partially washed out 5 or 6 yrs ago. At higher flows some flow goes through culvert, and some flow goes over road. At low flow, all flow goes through severely undersized culvert.

Workshop Summary Anchor QEA led the workshop and covered Introductions, Workshop Purpose and Approach, and Methods. Greg Hueckel was invited as a moderator to help keep the workshop on task and on time.

Greg is also working with the Flood Authority to develop a list of flood relief projects, and the Authority wants to ensure that the enhancement projects will be complementary to the flood relief projects.

Below is a summary of the workshop, discussions, and highlighted action items from those discussions.

Action items are called out, except those to be conducted by Anchor QEA during the continued development of the project.

Workshop highlights: • Jim Shannon of Anchor QEA led the workshop. This included introductions, project background, project purpose, and workshop purpose and methods.

• The Chehalis River Comprehensive Salmon Enhancement Plan came about through the Engrossed Substitute House Bill 2020. This bill states that the Chehalis River Basin Flood Authority (CRBFA) shall “address the potential for flood mitigation through upstream water retention facilities, including benefits and impacts to fish and potential mitigation of impacts.”

• The CRBFA contracted with Anchor QEA to develop the Chehalis River Comprehensive Salmon Enhancement Plan to identify and prioritize salmon enhancement projects in Water Resource Inventory Area (WRIA) 23.

• The Anchor QEA scope contains two tasks: 1) to identify salmon habitat enhancement projects using existing literature and geographic information in WRIA 23; and 2) to prioritize identified enhancement projects and complete the Comprehensive Salmon Habitat Enhancement Plan.

• The purpose of the workshop was to bring Chehalis River Basin biologists and planners together to discuss potential enhancement projects and prioritization methods.

• Anchor QEA presented a list of potential projects (Table 1) for discussion. These projects were identified from existing data sources including culvert databases and lead entity restoration plans. Some suggested changes included adding a column to reflect the owner of proposed projects.

• These projects also were displayed on topographic maps at three stations throughout the room.

These maps were separated by management units (MU) defined in the Chehalis Basin Salmon Habitat Restoration and Preservation Work Plan for WRIAs 22 and 23 (2011). Topographic maps displayed projects from culvert databases, the WRIA 22/23 Limiting Factors analysis (Smith and Wegner 2001), the Chehalis Basin Salmon Habitat Restoration and Preservation Work Plan for WRIAs 22 and 23 (2011), PRisM database, the conceptual habitat database, and other sources.

• Anchor QEA also developed and presented relative elevation maps (also separated by MU) of floodplain areas to identify side-channel and off-channel areas that may have enhancement potential.

• Questions about the reasons/motive for the Chehalis River Comprehensive Salmon Enhancement Plan were discussed. It was explained that the CRBFA Projects Subcommittee is developing a list of flood relief (i.e., infrastructure) projects that are likely to take place in the Chehalis basin. The CRBFA is interested in developing a list of enhancement projects that could mitigate for these upcoming flood relief projects. Flood relief projects include levees, dikes, bank stabilization, and road infrastructure improvements.

• Bob Montgomery of Anchor QEA introduced the next stage of the workshop, which included individual and group discussions focused around the relative elevation maps and topographic maps. Workshop participants were invited to view each set of maps and identify projects that may have been completed or in progress and any additional projects not included on the maps.

• Jim Shannon of Anchor QEA led the discussion for the Black and Lincoln MUs and the mainstem Chehalis in those areas. Several culvert projects in the Black MU were already complete

including Bailey and Cedar Creek culverts. Wolf-Davis is complete and all of Davis Creek is passable now. The Porter/Oakville area was discussed as having the potential to improve offchannel rearing habitat. The Confederated Tribes of the Chehalis Reservation are currently doing restoration in this area. Comments on maps included the need to label projects on the maps and include land ownership/parcel data if possible (e.g., DNR ownership layer). Jim Shannon also received recommendations to contact Janel Spaulding (Coordinator of the Chehalis Basin Partnership), Lee Napier (WRIA 22/23 Lead Entity), and Scott Brummer and Bob Burkle of Washington Department of Fish and Wildlife (WDFW) for additional project information. **Action Items: Update project list and maps with suggestions and contact local biologists/planners.

Margaret Murphy of Anchor QEA led the discussion for the Boistfort MU and the mainstem Chehalis in those areas. There was a question regarding Elk Creek and why no projects were identified in this area as it is a significant stream. We are not aware of any projects here, but this may be an area to assess for preservation of salmon habitat. The area downstream of Pe Ell tends to get quite warm during the summer and precludes salmon use; a few participants wondered if instream or riparian projects could be conducted to reduce temperatures and create more nursery habitat. Someone also alerted the group to a riparian planting project partially funded by an Ecology 319 grant in the area between Doty and Pe Ell. **Action Items: Update project list and maps with suggestions and contact local biologists/planners.

Bob Montgomery of Anchor QEA led the discussion for the Skookumchuck and Newaukum MUs and the mainstem Chehalis in those areas. Several culvert replacement projects in the Skookumchuck MU are proposed or complete. This includes the downstream most barrier of China Creek and two culverts replaced with bridges on Scatter Creek near Tenino. **Action Items: Update project list and maps with suggestions and contact local biologists/planners The final part of the workshop focused on discussion about prioritization of projects. Questions and statements about prioritization included: 1. Who is going to fund this list of projects? Right now there is no funding for this list of projects. It is just a list to be used in future planning.

2. Should land ownership be factored into pritoritization? The likelihood of completing a project based on ownership could be a factor.

3. Is cost of the project a consideration? Not at this stage of the process.

4. Different project types should be prioritized with more or less weight such as fish passage versus floodplain improvement.

5. Sponsors are worried about ranking projects. If a project in a jurisdiction gets a low ranking for this exercise, then it may not get funding from other sources.

6. Will projects be categorized by subbasin or by project type?

7. Why are we prioritizing this list of projects? It is hard to separate the list and prioritization from what the projects are mitigating for. What is the project list for?

8. One suggestion was to prioritize by project type or by function; then one type of project is not valued against a project of a different type.

Conclusions and next steps were discussed. There are a wide range and number of opportunities in the basin to enhance salmon habitat. Our next step is to incorporate workshop suggestions and comments into a memorandum that will list potential enhancement projects in the basin. We ask that any further comments on the project list or prioritization methods be submitted by November 14, 2011. We will continue to work on a ranking/prioritization system to be included in the final report.
