Magnitude and Frequency of Floods in Small Drainage Basins in Idaho

Description: Abstract: A method which relates basin characteristics with peak flow characteristics is presented for determining magnitude and frequency of floods on streams with drainage areas between 0.5 and 200 square miles. Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several ar… more

An Evaluation of Water-Quality Data Obtained at Four Streamflow Daily-Record Stations in Idaho

Description: From introduction: This study is limited to four U.S. Geological Survey stream-flow stations located in Idaho (figure 1). The 6 to 22 years of stations were assembled and evaluated through use of computer techniques for data plotting and regression analysis developed by Steele (1972). Objectives of this evaluation were were (1) to show which parameters were highly correlative with the levels of specific conductance and(or) discharge and (2) to see if any changes in overall chemical character of… more

Preliminary Report on Uranium and Thorium Content of Intrusive Rocks in Northeastern Washington and Northern Idaho

Description: From summary: The purpose of this study was to delineate favorable areas for uranium resources in northeastern Washington and northern Idaho by identifying granitic rocks with relatively large amounts of uranium and (or) thorium. Results are based on analyses of 344 rock samples; 230 were collected during this study, and data for the rest were taken from previous publications.
