On June 27, 1975, the city of Ames and vicinity sustained severe flooding from Squaw creek and the south Skunk River. The storm which preceded the flood was net particularly outstanding in its intensity or duration. However, antecedent conditions plus the timing and direction of the storm were "ideally tuned" to cause the flood. In terms of magnitude of discharge as well as of damages this was the

Studies of the geothermal aspect-of the Bridge area of the Raft River basin in south-central Idaho (fig. 1) by the U.S. Geological Survey began in 1972 when Young and Mitchell (1973) made a geochemical and geologic reconnaissance of selected thermal waters in Idaho. The Bridge area had been designated the Frazier known geothermal resource area (Frazier KGRA) by the U.S. Geological Survey (Go

The Lincoln County coastal area is underlain by Tertiary volcanic and sedimentary rocks of low permeability that store only a small volume of the annual precipitation which averages 68 inches (1,730 millimeters). Consequently, the Tertiary units yield small quantities of water to wells and furnish little ground-water discharge to maintain the base flow of streams. Although streamflow is normally a

The purpose of this report is to present information that may enable water users, potential water users, and planners to estimate the likelihood of obtaining ground water in adequate quantity and of suitable quality at desired locations within the study area. The Drain-Yoncalla area is in Douglas County in southwestern Oregon, includes about 340 mi2 (880 km2), and lies within the Umpqua River drai

Irrigation has given a substantial boost to the economy in the Brooten-Belgrade and Lake Emily areas of Minnesota. The surficial outwash aquifer is capable of yielding sufficient quantities of water for irrigation over half of its area; the remaining part may be supplied by deep aquifers. Buried glacial outwash and Cretaceous sand aquifers, as thick as 50 feet occur to depths of 300 feet. In place

The U.S. Geological Survey, in cooperation with the North Central Texas Council of Governments, the Trinity River Authority of Texas, and the Texas Water Development Board, conducted two time-of-travel studies in the Trinity River basin in November and December, 1975.  Field data were collected on the East Fork Trinity River during November 18-22, 1975, and on the Elm Fork Trinity River during Dec

Channel-width measurements were used to estimate annual peaks with a recurrence interval of 10 years at 79 sites in Owyhee County, Idaho, and adjacent areas. These discharges and those from 33 gaging stations are plotted on a map of the area. The map will allow the user to interpolate between sites. (Woodard-USGS)
