The Wild and Scenic Upper Clackamas River Rating the Rapids Welcome to If you have ever considered whitewater boating, then you’ve probably seen the terms Class I, II, III, IV, V, and VI. But what do they mean? The Wild and Scenic The “International Scale of River Difficulty” is used to categorize river rapids on a scale of I to VI — with Class I Upper Clackamas River being the easiest. The system is not exact. Rivers do not always fit neatly into — Mt. Hood National Forest — one category and people interpret the classes differently. Variables in water and weather can also change a river’s difficulty. So, a class rating is only a guide. If you’re headed Whitewater Recreation Map out, check several sources beforehand and stay alert.

  • Historical Overview
    HISTORIC CONTEXT STATEMENT The following is a brief history of Oregon City. The intent is to provide a general overview, rather than a comprehensive history. Setting Oregon City, the county seat of Clackamas County, is located southeast of Portland on the east side of the Willamette River, just below the falls. Its unique topography includes three terraces, which rise above the river, creating an elevation range from about 50 feet above sea level at the riverbank to more than 250 feet above sea level on the upper terrace. The lowest terrace, on which the earliest development occurred, is only two blocks or three streets wide, but stretches northward from the falls for several blocks. Originally, industry was located primarily at the south end of Main Street nearest the falls, which provided power. Commercial, governmental and social/fraternal entities developed along Main Street north of the industrial area. Religious and educational structures also appeared along Main Street, but tended to be grouped north of the commercial core. Residential structures filled in along Main Street, as well as along the side and cross streets. As the city grew, the commercial, governmental and social/fraternal structures expanded northward first, and with time eastward and westward to the side and cross streets. Before the turn of the century, residential neighborhoods and schools were developing on the bluff. Some commercial development also occurred on this middle terrace, but the business center of the city continued to be situated on the lower terrace. Between the 1930s and 1950s, many of the downtown churches relocated to the bluff as well.

  • Timing of In-Water Work to Protect Fish and Wildlife Resources
    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.

  • Appendix E: the City's Natural Environment
    APPENDIX E The City’s Natural Environment APPENDIX E The City’s Natural Environment The City’s Environmental Setting General Characteristics Portland is situated at 20 feet above sea level, near the confluence of the Columbia and Willamette rivers, about 65 miles inland from the Pacific Ocean. It lies midway between the lower Coast Range to the west and the high Cascades Range to the east, each about 30 miles distant. Portland’s varied topography includes steep hills, isolated volcanic cones, low rolling hills and extensive flat areas. The area is composed primarily of alluvial deposits and Columbia River basalts. Much of the city is located in the Willamette Valley Plains ecoregion, although steeper portions of the Tualatin Hills on the west side are characteristic of Willamette Valley Hills and Coastal Mountains ecoregions (Clarke and others 1991). Portland has a mild marine climate that is heavily influenced by the mountain ranges east and west of the city. The Coast Range protects the Portland area from Pacific storms, while the Cascades prevent colder continental air masses from invading western Oregon. In winter, the average temperature is 40°F and the average minimum temperature is 34°F. In summer the average temperature is 65°F with an average daily maximum of 74 to 78°F (Rockey 2002). The Cascades also lift moisture-laden westerly winds from the Pacific, driving local rainfall patterns. Average annual rainfall in the Portland area is approximately 37 inches. Nearly 90 percent of the annual rainfall occurs from October through May. Only 9 percent of the annual rainfall occurs between June and September, with 3 percent in July and August.

  • An Abstract of the Dissertation Of
    AN ABSTRACT OF THE DISSERTATION OF Peter J. Wampler for the degree of Doctor of Philosophy in Geology presented on July 14, 2004. Title: Contrasting Geomorphic Responses to Climatic, Anthropogenic, and Fluvial Change Across Modern to Millennial Time Scales, Clackamas River, Oregon. Abstract approved: Gordon E. Grant Geomorphic change along the lower Clackamas River is occurring at a millennial scale due to climate change; a decadal scale as a result River Mill Dam operation; and at an annual scale since 1996 due to a meander cutoff. Channel response to these three mechanisms is incision. Holocene strath terraces, inset into Pleistocene terraces, are broadly synchronous with other terraces in the Pacific Northwest, suggesting a regional aggradational event at the Pleistocene/Holocene boundary. A maximum incision rate of 4.3 mm/year occurs where the river emerges from the Western Cascade Mountains and decreases to 1.4 mm/year near the river mouth. Tectonic uplift, bedrock erodibility, rapid base-level change downstream, or a systematic decrease in Holocene sediment flux may be contributing to the extremely rapid incision rates observed. The River Island mining site experienced a meander cutoff during flooding in 1996, resulting in channel length reduction of 1,100 meters as the river began flowing through a series of gravel pits. Within two days of the peak flow, 3.5 hectares of land and 105,500 m3 of gravel were eroded from the river bank just above the cutoff location. Reach slope increased from 0.0022 to approximately 0.0035 in the cutoff reach. The knick point from the meander cutoff migrated 2,290 meters upstream between 1996 and 2003, resulting in increased bed load transport, incision of 1 to 2 meters, and rapid water table lowering.

  • 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.

Every village of any size or significance had a recognized leader or chief, and constituted a named local group with which its members identified themselves. Although the villages themselves are long vanished, early travelers, missionaries, and settlers have left us eyewitness accounts of what some were like.
