In-stream actions to improve fish habitat: Juvenile densities at log jams are 5X greater than that of main channel pools without large wood • From snorkel surveys of log jams in summer 2014 Still Creek Restoration Location Still Creek is located on the Zigzag Ranger District of the Mt. Hood National Forest in Northwest Oregon near the town of Rhododendron. The watershed area is over 21 square miles and extends about 14 miles from its headwaters on the flank of Mt. Hood to its confluence with the Zigzag River which is a tributary to the Sandy River. Still Creek is designated as critical habitat for threatened lower Columbia River coho, spring Chinook, and winter steelhead and 1 of 2 Watershed Restoration Action Plans (WRAP) identified on the Mt. Hood National Forest. Description Though still relatively productive, the aquatic and floodplain habitat of Still Creek has been impaired by the legacy effects of land use. Large floods in the 1960’s caused flood damage to nearby summer cabins and other infrastructure, which resulted in the US Army Corp of Engineers, US Forest Service and others removing large wood and boulders from the river channel. That work simplified the river corridor and led to increased hydraulic efficiency resulting in high velocities and shear stress within the channel. Still Creek pre-1964 cleanout Bulldozer removing wood and boulders from Still Creek main channel. 1964 Overall habitat diversity and complexity was reduced by removing roughness, overhanging cover, and lateral floodplain connectivity. Side channels, meanders, wood jams with scour pools, and pool tail-outs crucial to providing habitat for salmon and steelhead were lost. Past timber harvest along with recreation and road building activities converted the project area floodplain from conifers to deciduous species reducing natural inputs of large wood. The long term goal of the Still Creek restoration is to accelerate the recovery of naturally functioning conditions within stream channels and riparian areas and restore production of juvenile and adult coho salmon, spring Chinook Still Creek post- 1964 cleanout salmon, winter steelhead and cutthroat trout. Still Creek Reach Delineation Nine reaches (RM 1.78 to 8.05) based on physical surveys, contour map analysis, LiDAR data, and aerial photography. Restoration goalsRhododendron and objectives were developed for each reach based on current physical conditions, hydraulic equation predictions, and reference reaches. 20 Road Bridge Zigzag River Cabins Reach Mars Attacks Reach Cool Creek Straights Pumpkin Patch ReachCompression Reach Reach Elder Growth Reach Headwaters Canyon Reach Nirvana Reach From 2012 to 2014, the Forest Service and Sandy River Basin Partners have concentrated in reaches with the most potential to increase salmon and steelhead production. To address the main limiting factor for salmonid production in Still Creek, we substantially increased floodplain connectivity for juvenile rearing and refugia.

    OREGON GUIDELINES FOR TIMING OF IN-WATER WORK TO PROTECT FISH AND WILDLIFE RESOURCES June, 2008 Purpose of Guidelines - The Oregon Department of Fish and Wildlife, (ODFW), “The guidelines are to assist under its authority to manage Oregon’s fish and wildlife resources has updated the following guidelines for timing of in-water work. The guidelines are to assist the the public in minimizing public in minimizing potential impacts to important fish, wildlife and habitat potential impacts...”. resources. Developing the Guidelines - The guidelines are based on ODFW district fish “The guidelines are based biologists’ recommendations. Primary considerations were given to important fish species including anadromous and other game fish and threatened, endangered, or on ODFW district fish sensitive species (coded list of species included in the guidelines). Time periods were biologists’ established to avoid the vulnerable life stages of these fish including migration, recommendations”. spawning and rearing. The preferred work period applies to the listed streams, unlisted upstream tributaries, and associated reservoirs and lakes. Using the Guidelines - These guidelines provide the public a way of planning in-water “These guidelines provide work during periods of time that would have the least impact on important fish, wildlife, and habitat resources. ODFW will use the guidelines as a basis for the public a way of planning commenting on planning and regulatory processes. There are some circumstances where in-water work during it may be appropriate to perform in-water work outside of the preferred work period periods of time that would indicated in the guidelines. ODFW, on a project by project basis, may consider variations in climate, location, and category of work that would allow more specific have the least impact on in-water work timing recommendations.

Constructed between 1941 and 1969, these structures function in collaboration to comprise the Willamette River Basin Reservoir System (WRBRS). The motivation for this project derives from a growing awareness of the biophysical impacts that dam structures can have on riparian habitats. This project compares each of the 13 dams being assessed, to prioritize their level of utility within the system.

  • Lower Columbia Chum
    Oregon Native Fish Status Report – Volume II Lower Columbia Chum Existing Populations This SMU consists of seven historic populations which are extinct (Table 85). This conclusion is supported by spawning surveys from the past several years. Ollerenshaw (2001) reported on chum spawner surveys from throughout the lower Columbia from the Youngs to the Columbia River Gorge tributaries. In 2001, after 79 surveys in 27 streams, no live or dead chum, and no chum redds were observed. In 2000, only one chum was observed in the South Fork Klaskanine River, and in 1999, more limited sampling yielded two live chum and one dead chum. A limited number of chum are captured at the Big Creek hatchery trap each year. Between 1990 and 2004, zero to 27 fish have been trapped annually. It has been proposed that recent chum returns to Oregon tributaries are simply stray chum returning as part of healthier runs to Washington tributaries to the lower Columbia. Loss or severe degradation of estuarine and lower river habitat has been implicated as a major cause for the extinction of chum runs in the lower Columbia River tributaries of Oregon. Table 85. Population list and existence status for the Lower Columbia Chum SMU. Exist Population Description No Youngs Youngs Bay tributaries. No Big Big Creek basin plus other Columbia River tributaries from Mill to (and including) Hunt Creek. No Clatskanie Clatskanie River basin plus Columbia River tributaries downstream to include Plympton Creek and upstream to include Beaver Creek. No Scappoose Scappoose Creek basin plus Columbia River tributaries downstream to Goble Creek and upstream to mouth of Willamette River.

  • The AOCC's Efforts to Log Protected Public Land
    The AOCC’s Efforts to Log Protected Public Land The Association of O&C Counties (AOCC) has supported and lobbied in favor of a controversial logging bill known as the Resilient Federal Forests Act (HR 2936), which would remove protections for public lands and waterways in Clackamas County and throughout Oregon. The AOCC has done media work to promote the legislation and in June of 2017, the President of the Association actually traveled to DC to testify before a Congressional Committee in support of this legislation. I. Threats to protected public lands in Clackamas County posed by HR 2936* Sec. 913 of the AOCC-supported bill would require all BLM forestlands, including 2.1 million acres of O&C lands, to be managed for the primary purpose of timber production. This provision would rescind conservation protections for the following public lands in Clackamas County and open these lands to logging: • Table Rock Wilderness • Salmon Wild & Scenic River • Clackamas Wild and Scenic River • South Fork Clackamas Wild & Scenic River • Sandy River State Scenic Waterway • Molalla State Scenic Waterway and recreation corridor • Wildwood Recreation Site • The Congressionally-protected Mount Hood Corridor (Clackamas County supported this legislation) • Sandy River Gorge Area of Critical Environmental Concern • Williams Lake Area of Critical Environmental Concern • Soosap Meadows Area of Critical Environmental Concern • Wilhoit Springs Area of Critical Environmental Concern • Areas designated as reserves for threatened species and to protect streams in the 2016 BLM Resource Management Plan Table Rock Wilderness *Note: Days before the bill passed the House, HR 2936 was amended to exclude Wilderness and Wild and Scenic Rivers from this logging mandate; however, the AOCC supported the original bill that would have removed protections for these areas.
