The Ecology of Stream and Riparian Habitats of the Great Basin Region

Description: "The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).

Map Showing Outcrops of Pre-Quaternary Basaltic Rocks, Basin and Range Province, Oregon

Description: From introduction: This map report is one of a series of geologic and hydrologic maps covering all or parts of States within the Basin and Range province of the western United States. The map reports contain information on subjects that characterize the geohydrology of the province, including the ground-water hydrology, ground-water quality, surface distribution of selected rock types, tectonic conditions, areal geophysics, Pleistocene lakes and marshes, and mineral and energy resources.

Debris Flow Hazard Assessment for the Oregon Caves National Monument

Description: From introduction: Of the various hydrologic hazards in our environment, the mass movement of earth material caused by excess moisture can be one of the most destructive. These events often go unnoticed because they occur in unpopulated mountainous terrain during winter seasons. This was not the case in December 1964, when a major debris flow occurred in the Cave Creek drainage of the Oregon Caves National Monument. In March 1982, the National Park Service (NPS) requested a study be made to app… more

Hydrology of the Newberry Volcano Caldera, Oregon

Description: From abstract: Precipitation in the Newberry caldera is nearly in balance with evaporation, evapotranspiration, and and streamflow. A small surplus of water, estimated to be in the range 2,500 to 6,500 acre-feet, is available annually for recharge to deep aquifers beneath the caldera floor.

Magnitude and Frequency of Floods in Eastern Oregon

Description: From purpose and scope: This report describes methods for estimating the magnitude and frequency of floods at ungaged sites on streams with unregulated flow in eastern Oregon. The purpose is to provide a method to estimate flood magnitude and frequency and to present the supporting data. The report is based on data from nearly all unregulated streams (or data from regulated streams prior to their regulation) where gaging stations have been operated.

Storm Runoff as Related to Urbanization Based on Data Collected in Salem and Portland, and Generalized for the Willamette Valley, Oregon

Description: Abstract: Storm runoff as related to urbanization is defined by a series of regression equations for Salem and for the Willamette Valley, Oregon. In addition to data from 17 basins monitored in the Salem area, data from 24 basins gaged in a previous study in Portland, Oregon-Vancouver, Washington were used defining the Willamette Valley equations. Basins used to define equations ranged in size from 0.2 to 26 square mi. Rainfall intensity varied from 1.8 to 2.2 in. for the 6-hour, 0.020 exceedan… more

National Uranium Resource Evaluation: Vya Quadrangle, Nevada, Oregon, and California

Description: From Introduction: "The Vya 2º quadrangle (Fig. 1), in northwestern Nevada and small portions of California and Oregon, was evaluated to identify geologic environments and to delineate areas that have characteristics favorable for uranium deposits. Reconnaissance sampling in the Vya Quadrangle began in 1978, but final evaluation of the uranium favorability of the quadrangle was began in 1978, but final evaluation of the uranium favorability of the quadrangle was begun in June 1980."

Baker 1° x 2° NTMS Area, Oregon and Idaho: Data Report (Abbreviated)

Description: From introduction: The data presented here are reconnaissance data intended for use in identifying broad areas for further study. While care has been taken to provide reliable sampling and analyses, verification of individual analyses is beyond the scope of this report. The data should be viewed statistically because "one-point anomalies" may be misleading. Regional trends, however, should be reliable. This report is one of a series presenting data obtained by SRL reconnaissance.
