postClient: Tualatin River Watershed Council

Waterways staff prepared engineering designs and specifications to improve passage for steelhead and cutthroat trout on a headwater tributary to the Tualatin River in Washington County, OR. The site consisted of a seasonal flashboard dam. Downstream of the flashboard dam the channel had incised 3-feet creating a fish passage barrier under most flow conditions. The design consists of a series of five rock weirs to build the bed up downstream of the structure and provide fish passage under all flow conditions by creating a backwater condition at the dam. Waterways assisted the TRWC with the permitting and construction supervision. The project was constructed in Summer 2008.

Waterways staff led an interdisciplinary team to assess existing conditions within the Blackwood Creek Watershed. Blackwood Creek is a major tributary to Lake Tahoe, drains a mix of steep volcanic and granitic terrain, has a high bedload transport rate, and was historically impacted by grazing, logging, and instream gravel mining. Key impacts identified during the study were excessive bank erosion and channel widening associated with channel incision and loss of floodplain connectivity and the presence of several fish passage barriers. To restore the physical processes that sustain channel morphology and biological function, an aggressive, long-term restoration strategy was proposed.

Waterways, in coordination with the USFS Lake Tahoe Basin Management Unit (LTBMU) and Swanson Hydrology, has developed designs to restore the mainstem and tributaries of Cold Creek in the High Meadow Complex (HMC) near South Lake Tahoe, California. The basic restoration objective is to increase soil moisture within approximately 70 acres of meadow area by modifying the morphology and hydrology of the streams in a manner consistent with natural geomorphic processes. Work involves re-constructing approximately 8,700 linear feet of channel and raising the elevation of the streambeds by 2 to 4 feet. The project will significantly increase the diversity and density of meadow wetland vegetation species and shift some areas from seasonally dry and sparse mesic meadows to wet meadow conditions.

The project’s three-year construction plan was completed in 2012, with Waterways providing on-site supervision.

Waterways was retained by the Resource Conservation District of Santa Cruz County (RCD) to prepare a sediment source analysis and action plan for the recently acquired Geyer Quarry property. The Land Trust of Santa Cruz County purchased the property in 2008 to provide protection to a portion of the unique and delicate Sandhill ecosystem that extends from Bonny Doon through the Scotts Valley area of the Santa Cruz Mountains. Mining activity, road construction, logging, and off‐highway vehicle (OHV) use have exposed steep, denuded hillslopes in many locations throughout the parcel. These sources of erosion have caused excessive sediment delivery to the San Lorenzo River and its key tributaries (in this case Bean Creek and Zayante Creek) resulting in impacts to salmonid habitat.

Gooseneck Creek, tributary to Mill Creek and the South Yamhill River, is an important tributary for steelhead/coho salmon spawning and rearing. The project area is located above the confluence with Mill Creek in a portion of the channel that was historically impacted by aggregate mining. Waterways was contracted by the Greater Yamhill Basin Council to develop a restoration design for approximately 2,000 feet of Gooseneck Creek that was incised down to bedrock due to past mining activities and historic plugging of a secondary channel. Confinement of the channel, in-channel mining activities, and loss of secondary channels had all but eliminated the natural pool-riffle morphology with a consequent loss of aquatic and riparian habitat.

Waterways assisted CWS and DSL in the planning and design of a 20 acre mitigation bank in the Tualatin River Watershed to provide wetland, temperature, and salmon credits.  In addition to providing purchasable credits, the project simultaneously tested a function-based accounting system developed by the Willamette Partnership’s Counting on the Environment program (http://www.willamettepartnership.org). This program was developed with the help of public, private, and non-profit stakeholders to develop a shared accounting system for quantifying impacts and benefits to ecosystem services for application to ecosystem markets. The Partnership completed a test version for water temperature, wetlands, salmonid habitat, and upland prairie that was applied to pilot projects in the program. Half Mile Lane was one of the pilot projects that tested three of these services, and was the only pilot site thus far that resulted in real-world transactions. Therefore, this project tested not only the ecosystem credit calculator, but also the sequence of developing, selling and buying ecosystem credits.

In 2000, the Scappoose Bay Watershed Council (SBWC) completed a watershed assessment for the streams and catchments that enter Scappoose Bay. The watershed assessment identified several areas of concern affecting watershed and ecosystem health. Of particular concern was the potential impact that incision has on channel and floodplain interaction and the ability of the stream to support and maintain good aquatic habitat. A 5 mile stretch of South Scappoose Creek that flows through the City of Scappoose was determined to have high priority for further assessment. It was identified as a priority for further assessment due to local concerns about erosion and flooding and the opportunities to enhance conditions for salmon and other organisms.
