Waterways Consulting recently completed a restoration plan for Jackson and Netarts Creeks for Oregon Parks and Recreation District at Cape Lookout State Park.  The focus of the effort was to evaluate the hydrology, geomorphology, and habitat conditions of Jackson Creek, the principle stream that flows through Cape Lookout.  Approximately 60 years ago, a portion of Jackson Creek was diverted to Netarts Bay to increase freshwater flows into Netarts Bay with the hope of improving the commercial oyster beds.  Impacts associated with the diversion and associated flow split were addressed in the restoration plan as well as opportunities for enhancement of the Jackson Creek mainstem downstream of the diversion site.

Waterways was retained by the Scappoose Bay Watershed Council to develop bid-ready engineering drawings for six culverts on Salmon and Cox Creeks in the Scappoose Bay Watershed that were identified as high priority fish passage barriers during an assessment conducted in 2001.  The design approach consisted of replacing each culvert with a bottomless arch culvert using streambed simulation criteria established by NOAA Fisheries and Oregon Department of Fish and Wildlife.

Waterways staff was retained to develop a fish passage improvement design for a concrete culvert that was hindering fish passage on Valencia Creek, in Santa Cruz County. Plans were developed to construct a concrete fish ladder structure, per design criteria established by the National Marine Fisheries Service (NMFS) and the California Department of Fish and Game (CDFG).

GEOMORPHIC ANALYSIS OF THE MIDDLE REACH OF THE RUSSIAN RIVER
Waterways, in cooperation with Swanson Hydrology and Geomorphology, is in the process of completing a detailed hydraulic, geomorphic and sediment transport analyses for the Russian River’s Middle Reach, near Healdsburg. This work focuses on the effects of in-stream mining and other human activities on channel morphology and flood capacity. A chrono-sequence of topographic surfaces representing the channel and floodplain were analyzed to calculate volumetric changes in channel geometry over the past 20 years. Then, a hydraulic model was constructed along 5 miles of the Russian River to evaluate land use impacts on flood elevations.

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.

Fox Creek has been identified as an important spawning and rearing tributary to the North Fork of the John Day River in Eastern Oregon.  Impacts to the stream and watershed include fish passage barriers associated with passive diversion structures, water withdrawals during the critical low flow summer season, lack of adequate fish screening at water diversion sites, and severe channel incision that was causing reductions in water quality associated with bank erosion and loss of a continuous riparian canopy, loss of functional floodplain habitat, and conversion of productive hay fields to marginal rangeland as water tables declined.  These changes were having a noticeable impact on the economic viability of the land and the sustainability of natural ecological processes.

post trail webClient:City of Watsonville

The CARE project includes an ADA compliant pedestrian and bicycle trail providing community access to through a riparian corridor along the Pajaro River, near its outlet to the Pacific. The trail was designed with a surface that could be easily maintained following periodic inundation and fine sediment deposition within the floodplain through which it traverses. The trail provides an outlet to a scenic overlook on the Pajaro River, as well as to a boat launching ramp.
