wes2 RCClient: Clackamas County, Water Environment Services

Since 2009, Waterways staff has worked with Clackamas County’s Water Environment Services (WES) on Action Planning and Geomorphic Monitoring efforts in the more urbanized portions of Clackamas County. In 2008 and 2009, Waterways was an integral member of a team of consultants that prepared Watershed Action Plans (WAP) for the Kellogg/Mt. Scott and Rock Creek watersheds. Waterways prepared the hydrologic and geomorphic sections of the Action Plan for each basin and assisted in the development of a subwatershed-scale risk assessment, identification of project priorities, and a tool-based identification of levels of service.

pads during constClient: USFS- Lake Tahoe Basin Management Unit

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.

The Boy Scouts of America own and operate an 800-acre property on the Little Sur River that is used as a summer camp. A flashboard dam was installed in the 1950s to create an impoundment for recreational and educational uses. The seasonal operation of this dam impeded juvenile and adult steelhead passage at the site

Waterways staff assisted Granite Construction Company with planning, design, and permitting of a proposed off-channel gravel extraction project on the Kunzler Ranch property, located at the confluence of Ackerman Creek and the Russian River, in the Ukiah Valley of Mendocino County. Waterways has conducted hydrologic, hydraulic, and geomorphic analyses to assess flooding impacts, habitat development potential, and channel stability at the proposed project site, under both project-life and reclamation phases.

landfilla panClient: City of Watsonville

Waterways staff developed a restoration plan for an area in the Watsonville Slough near Ramsay Park. Initial assessment of the Project Area identified an old landfill adjacent to Ramsay Park as a high priority site to develop plans for restoration project implementation. The Ramsay Park site was part of a larger restoration planning process that identified and prioritized a range of sites in the area (including the landfill site) A complete restoration plan for the Ramsay Park was developed to a level for project implementation. This included a hydrologic and ecologic assessment, a biotic report, wetland delineation, engineering plans, and a design report. The design aimed to create a wetland setting with irregular shorelines, suitable vegetation and natural wetland features that would serve to restore and enhance wildlife habitat and wetland functions on site.

PA210029webClient: Necanicum River Watershed Council


Waterways was hired to develop an engineered solution to address a high priority fish passage site on the South Fork Necanicum.  The project site consists of a 6-foot high diversion dam and intake structure.  The objectives of the project were to provide unimpeded passage for all species and life histories of salmonids present in the South Fork, meet NMFS and NOAA Fisheries fish screening guidelines, and provide a reliable source of water to the City of Seaside according to their existing water right.  Specific project tasks include preparing a set of alternatives for review by a technical advisory team, preparation of preliminary engineering drawings for the selected alternative, preparation of a water management plan that identifies potential changes in the operation and management of the diversion as a result of the modifications, and preparation of the final engineering drawings.

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.
