Compilation of hydrologic data, Green Creek, Brazos River basin, Texas, 1966
In 1950 the U. S. Soil Conservation Service began construction of floodwater-retarding structures in Texas under authorities granted by the Congress. These authorities provide, where economically feasible, that the program be applied to tributary watersheds of 240,000 acres or less. The usual practice has been to control flood runoff from approximately 50 percent of the watershed by a system of floodwater-retarding structures located on headwater subwatersheds of generally less than 10 square miles.

Hydrologic data for water-management plans—A resource for Tribal Governments in Oklahoma
Introduction The major streams in Oklahoma, and the alluvial aquifers associated with those major streams, are important resources for the 39 federally recognized Tribes in Oklahoma. Many Tribal Governments are interested in developing water-management plans (hereinafter referred to as “water plans”) to preserve water resources for the future. This report provides a general overview of the types of information and data needed to prepare comprehensive water plans. To assist Tribes in the development of water plans, the U.S. Geological Survey, in cooperation with the Bureau of Indian Affairs, has outlined the steps necessary for creation of such plans.

A century of hydrologic data collection prepares western Long Island for current and future water-resources challenges
Freshwater is a vital natural resource. New York is a water-rich State; however, even here, the economical use of water resources is needed to ensure there is enough water of adequate quality for human and ecological needs—now and into the future. Nowhere in New York is this more evident than on Long Island where public-water supply is obtained from the sole-source aquifers directly beneath the 3 million people that live there. The U.S. Geological Survey works in partnership with the Nassau County Department of Public Works and Department of Health to monitor streamflow, groundwater, water quality, and water use.

Hydrologic data from Nation, Kandik, and Yukon rivers, Yukon-Charley Rivers National Preserve, Alaska
Flow data were collected from two adjacent rivers in Yukon?Charley Rivers National Preserve, Alaska?the Nation River (during 1991?2000) and the Kandik River (1994?2000)?and from the Yukon River (1950?2000) at Eagle, Alaska, upstream from the boundary of the preserve. These flow records indicate that most of the runoff from these rivers occurs from May through September and that the average monthly discharge during this period ranges from 1,172 to 2,210 cubic feet per second for the Nation River, from 1,203 to 2,633 cubic feet per second for the Kandik River, and from 112,000 to 224,000 cubic feet per second for the Yukon River. Water-quality data were collected for the Nation River and several of its tributaries from 1991 to 1992 and for the Yukon River at Eagle from 1950 to 1994. Three tributaries to the Nation River (Waterfall Creek, Cathedral Creek, and Hard Luck Creek) have relatively high concentrations of calcium, magnesium, and sulfate. These three watersheds are underlain predominantly by Paleozoic and Precambrian rocks. The Yukon River transports 33,000,000 tons of suspended sediment past Eagle each year. Reflecting the inputs from its major tributaries, the water of the Yukon River at Eagle is dominated by calcium?magnesium bicarbonate.

Selected hydrologic data for the field demonstration of three permeable reactive barriers near Fry Canyon, Utah, 1996-2000
Three permeable reactive barriers (PRBs) were installed near Fry Canyon, Utah, in August 1997 to demonstrate the use of PRBs to control the migration of uranium in ground water. Reactive material included (1) bone-char phosphate, (2) zero-valent iron pellets, and (3) amorphous ferric oxyhydroxide coated gravel. An extensive monitoring network was installed in and around each PRB for collection of water samples, analysis of selected water-quality parameters, and monitoring of water levels. Water temperature, specific conductance, pH, Eh (oxidation-reduction potential), and dissolved oxygen were measured continuously within three different barrier materials, and in two monitoring wells. Water temperature and water level below land surface were electronically recorded every hour with pressure transducers. Data were collected from ground-water monitoring wells installed in and around the PRBs during 1996-98 and from surface-water sites in Fry Creek.

Selected hydrologic data for Little Cottonwood Creek, Salt Lake County, Utah, September 1998
Metals enter Little Cottonwood Creek in Salt Lake County, Utah, in drainage water that discharges from inactive mines in the watershed (fig. 1). As part of a study to evaluate the effects of this mine drainage on water quality, a sodium chloride tracer was injected into Little Cottonwood Creek during September 17-18, 1998. The purpose of the injection was to quantify stream discharge; to identify inflows, both those observable and those dispersed in the subsurface; and ultimately, to determine which areas within the watershed contribute the most metals to Little Cottonwood Creek. The purpose of this report is to make these data available to agencies responsible for managing the area’ s water resources and to supplement interpretive reports for this study.

Surface-water hydrologic data for the Houston metropolitan area, Texas, water years 1990-95
During water years 1990–95, data were collected at 24 U.S. Geological Survey streamflow-gaging stations, 21 rain gages, and 6 water-quality stations in the Houston metropolitan area, Texas. The data were collected as part of the Houston Urban Runoff Program, which began in water year 1964. Annual peaks were defined for the 24 streamflow-gaging stations in the study area. All stations had 10 or more years of record. Precipitation data from the 21 rain gages and discharge or stage data from 23 streamflow-gaging stations are available to develop storm hydrographs. One-hundred thirty-four samples were collected at six water-quality stations. The samples were analyzed for about 80 water-quality properties and constituents.

Construction, Geologic, and Hydrologic Data from Five Exploratory Wells on Rota, Commonwealth of the Northern Mariana Islands, 1999
Rota is the southernmost of the 14 small islands that make up the Commonwealth of the Northern Mariana Islands. Reduced springflow at Matan Hanom and As Onan springs occurred during a drought associated with the 1997-98 El Nino. Water from the two developed springs constituted the only municipal water source for the island at that time. In April 1998, reduced water supplies forced the Commonwealth Utilities Corporation to restrict water service in the principal villages of Songsong and Sinapalu for the duration of the dry season. In 1999, Five exploratory wells, EX-1 through EX-5 (CUC wells SP-MW1, SP-1, -2, -3, and SP-MW2), were drilled in the Sinapalu region of Rota to (1) assess the availability of fresh ground-water resources in an area where no other well information were available, and (2) to provide a new water source to help mitigate the impacts of drought associated with recurring El Nino weather events. The wells penetrated mainly light colored (dirty white to brownish), fragmental limestones containing abundant coral remains. Sustained-rate, recovery, and step-drawdown aquifer tests were attempted at each of the five exploratory wells to estimate aquifer properties in the vicinity of the wells and to assess the potential for new water sources. At wells EX-1 (CUC well SPMW1) and EX-5 (CUC well SP-MW2), attempts to conduct sustained-rate aquifer tests resulted in excessive drawdown to the pump intakes in the vicinity of the wells. At well EX-2 (CUC well SP-1), the maximum drawdown measured in the pumped well was 3.93 ft during 8 days of sustained pumping at an average rate of 187 gal/min. At well EX-3 (CUC well SP-2), the maximum drawdown measured in the pumped well was 2.31 ft during 8 days of sustained pumping at an average rate of 108 gal/min, and at well EX-4 (CUC well SP-3), the maximum drawdown measured in the pumped well was 3.27 ft during 8 days of sustained pumping at an average rate of 139 gal/min. Specific conductance at the end of 8 days of pumping was 403, 358, and 445 ?S/cm at well EX-2, EX-3, and EX-4 (CUC wells SP-1, -2, and -3), respectively.
