Surface water and climatologic data, Salt Lake County, Utah, water year 1981, with selected data for water years 1980 and 1982

Abstract

was an urban-runoff study done in cooperation with the Salt Lake County Division of Flood Control and Water Quality. The objectives of the urban-runoff study were to identify the impact of urban runoff on the quantity and quality of the water in the canals east of the Jordan River and on the major tributaries to the river.The second investigation, which was carried out from December 1979 to September 1983, is a study of water-quality problems in the Jordan River. The study was done primarily to provide information about toxic substances, dissolved-oxygen depletion, sanitary quality, and turbidity and suspended sediment in the Jordan River. It also was funded in part by the Salt Lake County Division of Flood Control and Water Quality.Several Salt Lake County employees assisted in the collection of waterquality samples from storm runoff. Of those employees, Lee R. Armstrong, Gilbert H. Heal, Steven J. Mitckes, and Ben Santistevan worked on a daily basis with the authors and made a significant contribution in the collection of the data contained in this report. Organizations that furnished data are acknowledged in the station descriptions in tables 1 and 4.Information for previously published water-discharge, water-quality, atmospheric-deposition, and precipitation data for Salt Lake County are reported by Pyper and others (1981); Dustin (1977); Hely and others (1971) and references that they cited; and Feth and others (1964). Additional waterdischarge and water-quality data, published annually by the U.S. Geological Survey, and climatologic data, published monthly by the National Oceanic and Atmospheric Administration, are available for Salt Lake County. (See for example, U.S. Geological Survey, 1982 and National Oceanic and Atmospheric Administration, 1982.) DATA-SITE NUMBERING SYSTEMS Climatologic stations listed in this report ha preceded by the letter "P." The sites are identified 1, 2, and 3 by precipitation symbol and site number, atmospheric-deposition collectors operated at the same number.All but five surface-water stations listed in this report have been assigned eight-digit numbers according to the U nationwide system of numbering streamflow stations, by major river basin and in downstream order. Thus, same e been assigned numbers on plate 1 and in tables Precipitation gages and site are assigned the S. Geological Survey'sThe numbers are assigned the first two digits of each eight-digit station number indicate the major river basin in which the station is located and the last six digits indicate 1 the relative downstream order of that station in the basin.The other five surface-water stations have been assigned 15-digit numbers based on the grid system of latitude and longitude. The system provides the geographic location and a unique number for the site. The 15-digit number consists of the first 6 digits denoting the degrees, minutes, and seconds north latitude, the next 7 digits denoting degrees, jninutes, and seconds west longitude, and the last 2 digits are a sequential r^umber within a 1-second...
