Hydrologic data for North Creek, Trinity River basin, Texas, 1979
This report contains rainfall and runoff data collected during the 1979 water year for the 21.6-square mile area above the stream-gaging station North Creek near Jacksboro, Texas. A continuous water-stage recording gage was installed at one representative floodwater-retarding structure (site 28-A) on Oct. 5, 1972. The data are collected to compute the contents, surface area, inflow, and outflow at this site. The stream-gaging station on North Creek near Jacksboro continuously records the water level which, with measurements of streamflow, is used to compute the runoff from the study area. Streamflow records at this gage began on Aug. 8, 1956. Detailed rainfall-runoff computations are included for one storm during the 1979 water year at the stream-gaging station. (USGS)
Hydrologic data for urban studies in the San Antonio, Texas, metropolitan area, 1978
Hydrologic investigations of urban drainage basins in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Houston, and San Antonio. Studies were completed in the Fort Worth metropolitan area at the end of the 1977 water year, and in the Dallas metropolitan area at the end of the 1979 water year. The Geological Survey, in cooperation with the Texas Department of Water Resources, expanded the existing streamflow network in the San Antonio metropolitan area in May 1968 to begin urban hydrology studies in this area. In September 1968, the program was further expanded to include the collection of water-quality data.
Water resources data for Texas, water year 1980, Volume 3: Colorado River basin, Lavaca River basin, Guadalupe River basin, Neces River basin, Rio Grande basin, and intervening coastal basins
Surface-water data for the 1980 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also included are crest-stage and flood-hydrograph partial-record stations, reconnaissance partial-record stations, and low-flow partial-record stations. Additional water data were collected at various sites, not part of the systematic data collection program, and are published as miscellaneous measurements. Records for a few pertinent stations in bordering States are also included. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Texas.
Wildlife hazards from Furadan 3G applications to rice in Texas
Mortality of birds, fish, frogs, crayfish, earthworms, and nontarget insects occurred in rice fields after treatments of Furadan 3G granules in 3 Texas counties in 1970 and 1973-75. Three western sandpipers ( Ereunetes mauri ), 1 pectoral sandpiper ( Erolia melanotos ), and 2 red-winged blackbirds ( Agelaius phoeniceus ) were found dead or moribund between 17 and 24 hours after treatment. Cricket frogs ( Acris crepitans blanchardi ) were intoxicated 15 minutes post-treatment, and mosquito fish ( Gambusia affinis ) showed effects 1 hour post-treatment. Mortality of mosquito fish, Gulf menhaden (Brevoortia patronus), Atlantic croaker (Micropogon undulatus), and European carp ( Cyprinus carpio ) usually occurred between 24 and 28 hours after treatment. Mortality of frogs, crayfish, and nontarget insects generally occurred in rice field water between 1 and 45 hours after treatment. Mortality of earthworms in soil persisted for 52 hours. As a replacement for aldrin in Texas rice fields, Furadan 3G appeared to cause less mortality of birds than aldrin, but Furadan 3G was toxic to birds, fish, and invertebrates.

Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1978
This report contains rainfall and runoff data collected during the 1978 water year for drainage basins of Joes Creek, Bachman Branch, Turtle Creek, Coombs Creek, Cedar Creek, White Rock Creek, Elam Creek, Fivemile Creek, Newton Creek, Whites Branch, Prairie Creek, Tenmile Creek, Duck Creek, and South Mesquite Creek in the Dallas, Texas metropolitan area. The information will be useful in determining the extent to which progressive urbanization will affect the yield and mode of occurrence of storm runoff. Detailed rainfall-runoff computations are presented for ten storm periods during the 1978 water year. (USGS)
Sediment and water discharge of the Colorado River at Matagorda, Texas: May 4-7, and June 7-11, 1979
The U.S. Army Corps of Engineers requested the U.S. Geological Survey to collect data on the Colorado River at Matagorda, Texas , to determine the total sediment discharge into Matagorda Bay if all the water from the Colorado River were diverted into the bay. Data were collected from two floods (May 4-7, and June 7-11 , 1979) with peak discharges of 24,900 cubic feet per second and 40,900 cubic feet per second. The total suspended-sediment discharge from the first flood was approximately 201,000 tons, and the total suspended-sediment discharge from the second flood was 630,000 tons. The volume of sediment from these two floods was approximately 970 acre-feet with approximately 20 acre-feet of this total being the bed load. (USGS)
Hydrologic data for urban studies in the Houston, Texas, metropolitan area, 1978
This report contains rainfall and runoff data collected during the 1978 water year for drainage basins in the Houston, Tex., metropolitan area. The information will be useful in determining the extent to which progressive urbanization will affect the yield and mode of occurrence of storm runoff. Rainfall-runoff computations are presented for three storm periods during the 1978 water year. (USGS)
