Ground-water data in the Baker County-northern Malheur County area, Oregon

Ground-water data for the Baker County-northern Malheur area, Oregon, are tabulated for the Bureau of Land Management. The data include well and spring records, a well-location map, drillers' logs of wells, observation-well hydrographs, and chemical analyses of ground-water samples. The reported yields of wells and springs in the area ranged from less than 1 to 2,500 gallons per minute. Dissolved

Water-quality data from five Oregon stream basins

The U.S. Geological Survey collected water-quality data in five Oregon stream basins during summer low-flow conditions in 1977 and 1978. During the two sampling periods, a total of 18 different sites were sampled. Several sites were sampled twice in 1977, and some sites were sampled in both 1977 and 1978. Included in the sampling were diel trace of dissolved oxygen, temperature, specific conductan

Magnitude and frequency of floods in western Oregon

A method for estimating the magnitude and frequency of floods is presented for unregulated streams in western Oregon. Equations relating flood magnitude to basin characteristics were developed for exceedance probabilities of 0.5 to 0.01 (2- to 100-year recurrence intervals). Separate equations are presented for four regions: Coast, Willamette, Rogue-Umpqua, and High Cascades. Also presented are va

Benthic invertebrates, periphyton, and bottom material and their trace-metal concentrations in Salmon Creek basin, Clark County, Washington

In 1978, data were collected for identification and quantification of benthic invertebrates, periphyton, and bottom material and their trace-metals concentrations from three sites in Salmon Creek basin, Wash. Metal analyses included arsenic, cadmium, chromium, copper, lead, zinc, selenium, and mercury. Physical data collected included water temperature, dissolved oxygen, pH, discharge, and size of

Monitoring water-quality during pilot-dredging operations in the Willamette and Columbia Rivers, Oregon

Water quality was monitored in the Willamette and Columbia Rivers during a pilot dredging operation on December 16, 1977. Monitoring included in-situ measurements of pH, temperature, dissolved oxygen, and conductivity in the Willamette and Columbia Rivers; analyses of dissolved ammonia, dissolved manganese, suspended-sediment concentration and particle size, loss on ignition, and total organic car

Storm-water data for Bear Creek basin, Jackson County, Oregon 1977-78

Storm-water-quality samples were collected from four subbasins in the Bear Creek basin in southern Oregon. These subbasins vary in drainage size, channel slope, effective impervious area, and land use. Automatic waterquality samplers and precipitation and discharge gages were set up in each of the four subbasins. During the period October 1977 through May 1978, 19 sets of samples, including two ba

Sediment sources and Holocene sedimentation history in Tillamook Bay, Oregon; data and preliminary interpretations

Surface and core sediments from Tillamook Bay, Oregon, have been analyzed to determine modern and Holocene sediment sources and sedimentation history. Heavy mineral analyses established three sediment sources: (1) the five major rivers draining the volcanic and associated sedimentary rocks of the Coast Range, (2) small streams draining the sedimentary uplands that form the shoreline adjacent to Ti

Rainfall-runoff data for selected basins, Portland, Oregon, and Vancouver, Washington, 1973-77

In the Portland-Vancouver area, storms and floods are presently being studied in 16 basins with drainage areas ranging from 0.21 to 6.63 square miles and with various basin slopes, degrees of imperviousness, and mixes of land use. Fanno Creek basin in Portland has the longest period of rainfall-runoff record, starting in 1973; Tryon Creek basin in Portland is next with a record starting in 1974. R

Hydrologic data in Bear Creek Basin and western Jackson County, Oregon, 1976-77

To determine irrigation return flow impacts on Meyer Creek and Griffin Creek, 12 sites were sampled prior to and during the irrigation season. Thirty-three sets of samples, consisting of irrigation inflow and outflow samples on farms, were collected to determine if the use of irrigation water was improving or degrading the water quality. One hundred fifty visits were made to tributaries and Bear C

Analysis of urban storm-water quality for seven basins near Portland, Oregon

Over a 1.5-year period, water-quality data were collected for seven small drainage basins in urban aeas of Portland, Oreg. Analysis of the data followed three approaches. First, the constituent concentrations were analyzed. Average concentrations of suspended sediment, settleable solids, and fecal coliform bacteria generally exceeded levels expected for secondary waste-treatment plant effluent, wh

Availability and quality of ground water in the Winston area, Douglas County, Oregon

A map of the Winston area, Douglas County, Oreg., shows areal geology and locations and chemical diagrams of wells with water analyses. Another map of the area has diagrams showing the depth to water, pumping level, total depth, and yields of selected wells. Reported yields of wells range from less than 1 to as much as 70 gallons per minute; the average is less than 10. A table listing chemical an

Water resources of the Umatilla Indian Reservation, Oregon

Water resources of the Umatilla Indian Reservation are poorly distributed both geographically and in time. On the reservation, only the Umatilla River and one of its principal tributaries, Meacham Creek, have significant perennial flows. Runoff of the principal streams is largely from snowmelt in the Blue Mountains and is highly variable. The principal aquifers are the Columbia River Basalt Group
