Geology and ground-water conditions of Clark County Washington, with a description of a major alluvial aquifer along the Columbia River
This report presents the results of an investigation of the ground-water resources of the populated parts of Clark County. Yields adequate for irrigation can be obtained from wells inmost farmed areas in Clark County, Wash. The total available supply is sufficient for all foreseeable irrigation developments. In a few local areas aquifers are...

Bodhaine, G.L.; Thomas, D.M.Effects of hydraulic and geologic factors on streamflow of the Yakima River Basin, Washington
The Yakima River basin, in south-central Washington, is the largest single river system entirely within the confines of the State. Its waters are the most extensively utilized of all the rivers in Washington. The river heads high on the eastern slope of the Cascade Mountains, flows for 180 miles in a generally southeast direction, and discharges...
Kinnison, Hallard B.; Sceva, Jack E.Ground water in the Pullman area, Whitman County, Washington
This report presents the results of an investigation of the ground-water resources of the Pullman area, Whitman County, Wash. The investigation war made in cooperation with the State of Washington, Department of Conservation, Division of Water Resources, to determine whether the 1959 rate of ground-water withdrawal exceeded the perennial yield of...
Foxworthy, B.L.; Washburn, R.L.Magnitude and frequency of floods in the United States. Part 13. Snake River basin
The magnitude of a flood of any selected frequency up to 50 years for any site on any stream in the Snake River basin can be determined by methods outlined in this report, with some limitations. The methods are not applicable for regulated streams, for drainage basins smaller than 10 or larger than 5,000 square miles, for streams fed by large...

Fahnestock, Robert K.Geology and ground-water resources of the Ahtanum Valley, Yakima County, Washington
The Ahtanum Valley covers an area of about 100 square miles in an important agricultural district in central Yakima County, Wash. Because the area is semiarid, virtually all crops require irrigation. Surface-water supplies are inadequate in most of the area, and ground water is being used increasingly for irrigation. The purpose of this...

Price, Charles E.; Hubbell, D.W.Floods in the Skagit River basin, Washington
According to Indian tradition, floods of unusually great magnitude harassed the Skagit River basin about 1815 and 1856. The heights of these floods were not recorded at the time; so they are called historical floods. Since the arrival of white men about 1863, a number of large and damaging floods have been witnessed and recorded. Data...

Newcomb, R.C.Availability of ground water at the border stations at Laurier and Ferry, Washington
In the Laurier area, Washington, the Kettle River has cut into crystalline rocks in the deepest part of the valley. Sand and gravel fill were deposited in the valley during Pleistocene time by melt water from glaciers, and subsequent erosion and alluviation formed three terrace levels. The highest level, on which Laurier Border Station is situated...

Ash collection buckets, installed on the flanks of Mount St. Helens...
A USGS scientist is collecting the ash from the bucket, which was taken back to the Cascades Volcano Observatory for analysis. Results help scientists understand more about the eruption that produced the ash and can give insight into what type of eruptions might occur in the future.

Erosional debris flows carve into Sasquach Steps at Mount St. Helens
The dark "muddy" looking area in the right foreground is old erosional debris flows from Step Channel (on right) over the years. The lighter ribbon of grey to the left of the darker area is a lahar from Loowit Channel from early morning of October 6, 2004. The yellowish-green color on the surface is plant growth.
