Hydrogeologic Framework of Sedimentary Deposits in Six Structural Basins, Yakima River Basin, Washington Prepared in cooperation with the Bureau of Reclamation, Washington State Department of Ecology, and the Yakama Nation Hydrogeologic Framework of Sedimentary Deposits in Six Structural Basins, Yakima River Basin, Washington Scientific Investigations Report 2006–5116 U.S. Department of the Interior U.S. Geological Survey Cover: Photograph of Clark Well No. 1, located on the north side of the Moxee Valley in North Yakima, Washington. The well is located in township 12 north, range 20 east, section 6. The well was drilled to a depth of 940 feet into an artesian zone of the Ellensburg Formation, and completed in 1897 at a cost of $2,000. The original flow from the well was estimated at about 600 gallons per minute, and was used to irrigate 250 acres in 1900 and supplied water to 8 small ranches with an additional 47 acres of irrigation. (Photograph was taken by E.E. James in 1897, and was printed in 1901 in the U.S. Geological Survey Water-Supply and Irrigation Paper 55.)

Mid-Columbia Recovery Unit Yakima River Basin Critical Habitat Unit 353 Bull Trout Final Critical Habitat Justification Chapter 11 U. S. Fish and Wildlife Service September 2010 Chapter 11. Yakima River Basin Critical Habitat Unit The Yakima River CHU supports adfluvial, fluvial, and resident life history forms of bull trout. This CHU includes the mainstem Yakima River and tributaries from its confluence with the Columbia River upstream from the mouth of the Columbia River upstream to its headwaters at the crest of the Cascade Range. The Yakima River CHU is located on the eastern slopes of the Cascade Range in south-central Washington and encompasses the entire Yakima River basin located between the Klickitat and Wenatchee Basins. The Yakima River basin is one of the largest basins in the state of Washington; it drains southeast into the Columbia River near the town of Richland, Washington. The basin occupies most of Yakima and Kittitas Counties, about half of Benton County, and a small portion of Klickitat County. This CHU does not contain any subunits because it supports one core area. A total of 1,177.2 km (731.5 mi) of stream habitat and 6,285.2 ha (15,531.0 ac) of lake and reservoir surface area in this CHU are proposed as critical habitat. One of the largest populations of bull trout (South Fork Tieton River population) in central Washington is located above the Tieton Dam and supports the core area.

  • Autogenic Cycles of Channelized Fluvial and Sheet Flow and Their
    RESEARCH Autogenic cycles of channelized fl uvial and sheet fl ow and their potential role in driving long-runout gravel pro- gradation in sedimentary basins Todd M. Engelder and Jon D. Pelletier* DEPARTMENT OF GEOSCIENCES, UNIVERSITY OF ARIZONA, 1040 E. FOURTH STREET, TUCSON, ARIZONA 85721, USA ABSTRACT The paleoslope estimation method uses a threshold-shear-stress criterion, together with fi eld-based measurements of median grain size and channel depth in alluvial gravel deposits, to calculate the threshold paleoslopes of alluvial sedimentary basins. Threshold paleoslopes are the minimum slopes that would have been necessary to transport sediment in those basins. In some applications of this method, inferred threshold paleoslopes are suffi ciently steeper than modern slopes that large-magnitude tectonic tilting must have occurred in order for sediments to have been transported to their present locations. In this paper, we argue that autogenic cycles of channelized fl uvial and sheet fl ow in alluvial sedimentary basins result in spatial and temporal variations in the threshold slope of gravel transport that can, under certain conditions, cause gravel to prograde out to distances much longer than previously thought possible based on paleoslope estima- tion theory (i.e., several hundred kilometers or more from a source region). We test this hypothesis using numerical models for two types of sedimentary basins: (1) an isolated sedimentary basin with a prescribed source of sediment from upstream, and (2) a basin dynamically coupled to a postorogenic mountain belt. In the models, threshold slopes for entrainment are varied stochastically through time with an amplitude equal to that inferred from an analysis of channel geometry data from modern rivers.

Offshore, west of the Island of Elba, magnetic and gravimetric data suggest the occurrence of N-S trending ridges that, for the very high magnetic susceptibility, have been interpreted as serpentinites, associated with other ophiolitic rocks (Eriksson and Savelli, 1989; Cassano et al., 2001; Caratori Tontini et al., 2004). Moving towards south in Tuscan domain, along N-S fault, there is clear evidence of off- shore gas seepage (mainly CH4), which can be related to recent extensional activity.
