SURFACE WATER AND CLIMATOLOGIC DATA, SALT LAKE
COUNTY, UTAH, WATER YEAR 1981, WITH SELECTED
DATA FOR WATER YEARS 1980 AND 1982
by H. F. McCormack, R. C. Christensen, D. W. Stephens, G. E. Pyper, J. F. Weigel, and L. S. Conroy
INTRODUCTION
This report contains precipitation, atmospheric-deposition, water- discharge and water-quality data collected in Salt Lake County as part of two investigations by the U.S. Geological Survey. The purpose of this report is to release data collected mainly during the 1981 water year. Selected data collected during the 1980 water year not previously published or revised and the 1982 water year also are included in this report.
The first investigation, which was carried out from September 1979 to August 1982, 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 water- quality 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 water- discharge 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 beenassigned eight-digit numbers according to the U nationwide system of numbering streamflow stations, by major river basin and in downstream order. Thus,

S. Geological Survey's The 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 grid. The complete 8- or 15-digit number for each streamflow and water- quality station, such as 101671^9 or 40443211155(1201, is used as a site- identification number on plate 1 and in tables 4, fi, and 6. Streamflow and water-quality stations operated at the same site are assigned the same number.
CLIMATOLOGIC DATA ji
Climatologic data listed in tables 1, 2, and |3 consist of records for daily precipitation, selected storm rainfall, and atmospheric deposition.
Daily Precipitation Records
Records of daily precipitation listed in sites, of which 16 contained recording gages and gages. These data were collected according to standards.

Atmospheric-Deposition Records
Atmospheric deposition, as dustfall and wet deposition, was monitored at six sites to determine the magnitude of atmospheric deposition on water- quality constituents found in storm runoff. Aerochem-Metrics model 301 wet- dry collectors were utilized at all sites. Dustfall was monitored as monthly accumulation with samples being collected generally on the first Tuesday of each month. Wet deposition was monitored by individual storm with samples collected and processed immediately following the storm. The data are listed in table 3.
SURFACE-WATER DATA
The surface-water data listed in tables M, 5 and 6 consist of water- discharge and water-quality data from continuous record sites, selected storm- runoff data from continuous-record sites, and miscellaneous data from nonrecording sites. Methods of collection and analysis of surface-water data and terms used in the tables are described by the U.S. Geological Survey (1982, p. 15-35).
Water-Discharge Records
Water-discharge records are given in table M for 48 continuous-record sites that comprise a complex system of natural streams, canals, and storm conduits as shown on plate 1. Miscellaneous discharge measurements and the locations at which they were made are given in table 6.
Water-Quality Records
Water samples for analysis were collected during base flow prior to storm runoff, and during selected storms; samples of streamflow also were collected monthly at all Jordan River sites. Water-quality data are listed in table M for 33 streamflow sites. A double date in table M indicates a composite sample initiated at the time given with the completion time given in the column titled "ending time." Miscellaneous water-quality data and the locations at which the data were collected are given in table 6.
Selected Storm-Runoff Records
Records of storm runoff at continuous-record sites were computed at 5- or 15-minute intervals for selected storms. The data for those storms are listed in table 5, which gives the storm runoff in cubic feet per second that occurred at the indicated time.
The use of brand names in this report is for identification only and does not constitute endorsement by the U.S. Geological Survey.
