This report presents fluvial sediment data collected primarily in response to the eruption of Mount St. Helens. To monitor the sediment transported by streams in the Mount St. Helens area and the particle-size distributions of the sediment, the Water Resources Division of the U.S. Geological Survey initially established 18 fluvial...

Seven test holes drilled in the Glacial Lake Agassiz Peatlands indicate that the thickness of surficial materials along a north-south traverse parallel to Minnesota Highway 72 ranges from 163 feet near Blackduck, Minnesota to 57 feet about 3 miles south of Upper Red Lake. Lenses of sand and gravel occur...

This report provides a record of the flood of September 16, 1975, and associated hydrologic data. These data can be used in making rational decisions in formulating effective flood-plain regulations that would minimize flood problems in the Tallaboa Valley.The Tallaboa Valley (fig. 1) lies on the southwestern coast of Puerto...

In 1960, the U.S. Geological Survey and the Kentucky Geological Survey began a program to map the State geologically at a scale of 1:24,000 and to publish the maps as 707 U.S. Geological Survey Geologic Quadrangle Maps. Fieldwork was completed by the spring of 1977, and all maps were published...

Methods of estimating annual mean and annual maximum chloride concentrations in streams were developed through multiple and simple linear regression techniques using data collected during the 1972-77 water years. Independent variables are easily obtainable parameters, such as total salt application within a basin, annual precipitation, and drainage basin characteristics. Methods...

Systematic collection of rainfall, runoff, and water-quality samples from three small urban areas of Broward County, Florida, were obtained between 1974 and 1977. Stormwater loads for 30 or more storms were computed for the residential, highway, and commercial investigation areas. Stepwise, multiple, linear regression models were constructed for total nitrogen,...

The production of crushed stone suitable for highway and general construction is a major industry in Georgia. The state ranks eighth in the nation in overall crushed stone production, and first in crushed granite production. Crushed stone production in Georgia in 1979 was 40,902,000 short tons worth $154,021,000 (D.H. White,...

The collection comprises over 120,000 maps, including some 15-minute quadrangle maps compiled by the U.S. Army Corps of Engineers, National Parks and Monument maps, River Survey maps, and selected Federal Highway Administration county planning maps. The collection will continue to grow as other types of maps are added....

In a recently signed letter, the Governor of North Dakota and the Assistant Secretary of the Interior for Fish and Wildlife and Parks charged a joint state-federal study group with examination of two separate questions: 1) mitigation for the Garrison Diversion Project; and 2) planning for long-range protection and preservation...

Eastern tent caterpillars, Malacosoma americanum (F.) (Lepidoptera: Lasiocampidae), and leaves of their host plant, black cherry, Prunus serotina Ehrh., were collected in May, 1978, at various distances from the Baltimore-Washington Parkway, Prince George's Co., MD, and were analyzed for lead by atomic absorption spectrophotometry. Caterpillars collected within 10 m of the parkway contained 7.1–7.4...

From October 1972 through September 1977, the effects of highway construction in the 38 square mile Blockhouse Creek basin were studied. Water discharge, suspended-sediment discharge, and stream-temperature data were collected at four stations in the basin. The 5-year period included 1 year before construction, 2 years during construction, and 2...

Construction of an interstate highway is planned near Rogers Lake in Dakota County, Minn. Samples of water and bed material were collected at six sites during March 1976 to April 1978 to determine selected physical, chemical, and biological characteristics before construction. Samples were collected at least twice during each season...

Three lakes in Dakota County were sampled five times during an 18-month period to determine baseline water quality prior to construction of an interstate highway. Results of physical measurements and chemical analyses showed that the lakes were shallow, nonstratified, and nutrient enriched. Considerable seasonal variations in dissolved solids, nutrient, and...

Urban stormwater data from four Miami, Fla. catchments were collected and compiled by the U.S. Geological Survey and were used for testing the applicability of deterministic modeling for characterizing stormwater flows from small land-use areas. A description of model calibration and verification is presented for: (1) A 40.8 acre single-family...

Procedures are defined for estimating the magnitude and frequency of future flood peaks and flood volumes and for estimating the expected hydrograph shape of rainfall-induced runoff of small streams in South Dakota. The procedures are applicable to flood flows that are not significantly affected by artificial storage or other manmade...

Station listings, basin and flow characteristics tables, and annual maximum discharges are presented for stations in West Virginia, Maryland, and Virginia that were used to develop flood-frequency relations for West Virginia. Also presented are figures showing approximate station location and areal coverage for both longterm and short-term stations that were...

The earthquakes of 24 January (Ms 5.8) 1980 north of Livermore, California, and 26 January (Ms 5.2), were accompanied by surface faulting in the Greenville fault zone and apparently in the Las Positas fault zone also. The surface faulting was discontinuous and of small displacement. The main rupture within the...

In 1960, floods caused extensive damage to agribusiness in Jumper Creek Canal basin. In 1962, a plan was developed for a proposed project to reduce the threat of floods. In 1976, a study of the hydrology of the basin was proposed to help evaluate this plan and to serve as...

Analysis of samples collected from the Arkansas River between Muskogee and Webbers Falls Lock and Dam, Oklahoma, in November 1978 showed that concentrations of polychlorinated biphenyls in the dissolved and suspended phases were less than the detection limit of 0.1 micrograms per liter. The maximum polychlorinated biphenyl concentration measured in...

The water supply for the Reedsport area is obtained from Clear Lake, a 310-acre coastal lake that contains 16, 600 acre-feet of water at full-pool. The lake receives about 6,000 acre-feet of water annually from runoff and direct precipitation, and it loses about 600 acre-feet by evaporation. The 2,100 acre-feet...

The Bureau of Land Management requested on May 3, 1979 that the U.S. Geological Survey determine the base (100-year) flood-plain limits at three sites (fig. 1) along the Trans-Alaska Pipeline System Highway (Haul Road) between the Yukon River and Prudhoe Bay in order to issue land-use permits. The Alaska Department...

A high-intensity summer rain estimated at 8 inches in 2 hours caused flooding on a small stream near Thornville, Ohio, destroying a culvert and highway fill on State Route 188. Computation of peak discharges of 3,250 feet3 per second at a site 4,400 feet above and of 4,050 feet3 per...

The Lemhi Pass district has the largest thorium resources of any vein district in the United States (Staatz and others, 1979, p. 10). Most of the resources occur in veins that have an average grade of between 0.1 and 2.0 percent Th02. More than 200 thorium-bearing veins have been mapped...
