This report is a result of recent studies of the Cenozoic stratigraphy and structure of the San Joaquin Valley that were directed at Cenozoic depositional and tectonic history. Most previous work on the Cenozoic has focused on the Quaternary surficial deposits and on the outcrops of older rocks at the margins of the valley, although ground-water resource studies of the upper Cenozoic deposits have used subsurface information (for example, Davis and others, 1959; Croft, 1972). One purpose of this report is to show the distribution and stratigraphic relations of Tertiary units under the valley and represents, in part, an attempt to extend correlations from Tertiary units previously recognized in outcrop at the margins of the valley into the subsurface. A second purpose is to depict the structure of the Tertiary rocks by cross sections and by a structure contour map of a middle Tertiary horizon.
\nThe emphasis in this report is on the Tertiary rocks of the northern part of the San Joaquin Valley, although pre-Tertiary stratigraphic units are shown on the cross sections where information was available. They serve to emphasize the discordance between the Neogene and the older units. Correlations of units in the Great Valley sequence (Late Jurassic to earliest Tertiary) are based mostly, with some modification, on the work of Hoffman (1964) and Callaway (1964), although the informal stratigraphic names used by those workers are not applied here.

Penobscot Bay is one of the major embayments along the U.S. Atlantic coast (fig. 1), extending more than 50 km from the Gulf of Maine to the mouth of the Penobscot River. The bay constitutes an area of about 1,100 km\" and is divided into three main passages by numerous islands.
\nThe bay and surrounding coastal area have had a complex history of glaciation and sea-level change since late Wisconsinan time. The last ice sheet advanced across the area about 20,000 years ago, eroding the bedrock surface, removing most older sediments, and isostatically depressing the crust (Schafer and Hartshorn, 1965; Stuiver and Borns, 1975; Thompson, 1979). Deglaciation followed between about 12,700–13,500 years ago and was accompanied by a marine transgression (because of crustal depression), with ice and sea in contact (Stuiver and Borns, 1975; Thompson, 1979, 1982; Smith, 1982). Isostatic recovery of the crust then caused the coast to emerge during the immediate postglacial period, and emergence was completed by about 11,500 years ago (Stuiver and Borns, 1975; Thompson, 1979, 1982; Thompson and Smith, 1983). Finally, resubmergence of the Maine coast has accompanied the Holocene rise of sea level that began about 9,000 to 11,000 years ago (Bloom, 1963; Kaye and Barghoorn, 1964; Schmitker, 1974; Oldale and others, 1983).
\nIn the maps presented here, we illustrate and briefly describe the sea-floor topography, bedrock morphology, and variable sediment thickness within Penobscot Bay that were either produced or modified during the period of geologic change since late Wisconsinan time.

Focus was placed on determining the distribution and age of plateau-capping basalts, and on mapping the eastern limits of Paleogene marine strata and the western limits of the nonmarine Comondu Formation. The area was also examined for outcrops of pre-Tertiary crystalline rocks, however, none were found.
\nMapping was done on aerial photographs and transferred, where possible, to 1:50,000-scale topographic base maps. Areas with roads were field checked; however, in the northeast part of the map area, lack of roads prevented field checks. Previous geologic surveys of parts of the map area were made by horseback in the early 1920's; reports were published by Darton (1921), Heim (1922), and Beal (1948). Subsurface data from petroleum exploration and a geologic map were incorporated in a regional study by Mina (1957). The first radiometric ages of rocks from the map area were published by Gastil and others (1979). Recently determined radiometric ages and chemical analysis of volcanic rocks were reported by Hausback (1984) and by Sawlan and Smith (1984). Our study incorporates geologic mapping with age control based on new radiometric ages as well as paleontology, Flows and tuffs were dated by the K-Ar method. Fossil ages are based on diatom and mollusk assemblages.

This report summarizes the methods of study and describes reconnaissance and site-selection procedures, locations and characteristics of the stations, instrumentation, and methods of collecting and storing data.\r\n\r\nThe first phase of this study involved an intensive field reconnaissance of about 7,000 sites, of which 32 basins were selected for detailed analysis. Drainage areas for the basins varied from 0.13 to 6.45 square miles, and main-channel slopes ranged from 7.6 to 276 feet per mile.\r\n\r\nFive years of 5-minute rainfall-runoff data will be colledted for each study site. These data will be used to calibrate and verify a rainfall-runoff model for each basin. The calibrated model will be used in conjunction with 80 years of National Weather Service 5-minute precipitation data to synthesize a representative 80-year streamflow record at each site. A Log-Pearson Type III frequency distribution will be applied to each record to define the magnitudes and frequencies of flood volumes at each site. These data will be used to develop regionalized multiple regression models for estimating flood-volume magnitudes and frequencies at small rural ungaged sites in Ohio.\r\n\r\nThe report also summarizes rainfall-runoff data collected from July 1981 through September 1983, but does not interpret the data. An average of eleven event periods per site were monitored where maximum 5-minute rainfall intensities varied from 0.02 to .067 inches and maximum peak discharges varied from 1 to 1,130 cubic feet per second.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr84470","usgsCitation":"Sherwood, J.M., 1985, Preliminary report on a study to estimate flood volumes of small rural

Data from these stations are provided to Federal, State, and local agencies that have a responsibility to issue flood warnings; to generate forecasts of water availability; to monitor flow to insure compliance with treaties and other legal mandates; and to manage reservoirs for hydropower, flood abatement, and municipal and irrigation water supply. In the mid-1970's, the escalation of data collection costs and a need for more timely data led the Arizona District to examine alternatives for remote data acquisition. On the basis of successful data communications experiments with NASA 's Landsat satellite, an operational system for satellite-data relay was developed in 1976 using the National Oceanic and Atmospheric Administrations 's (NOAA) Geostationary Operational Environmental Satellite (GOES). A total of 62 data collection platforms (DCP's) was operated in 1983. Satellite telemetry operations are controlled at the remote data-collection stations by small battery-operated data collection platforms. The DCP 's periodically collect data from the sensors, store the data in computer memory, and at preset times transmit the data to the GOES satellite. The satellite retransmits the data to Earth where a ground-receive station transmits or transfers the data by land communications to the USGS computer in Reston, Virginia, for processing. The satellite relay transfers the data from sensor to computer in minutes; therefore, the data are available to users on a near real-time basis.

A similar profile defines losing and gaining reaches for the average 3-day minimum discharge, 20-year recurrence interval, and the variability of that discharge along the river channels. The average 3-day minimum discharge, 20-year recurrence interval, ranged from 2.4 cubic feet per second for the site on East Piney River to 45.6 cubic feet per second at the Vernon gage, farthest site downstream in the study area. On the Piney River, the lowest 3-day, 20-year discharge, occurs at river mile 23.5, 0.1 river mile downstream from the confluence of the East and West Piney Rivers. Comparison of discharge measurements to recorded August discharges at the Vernon gage shows that the measurements represent base-flow conditions in the Piney River basin. The measurements and analyses can be used to formulate water management plans for use during droughts.
