INTRODUCTION

Water-resources data for the 2003 water year for Utah consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 169 gaging stations; stage and contents for 10 lakes and reservoirs; water quality for 22 hydrologic stations, and 36 wells; water levels for 68 observation wells; and precipitation for 2 stations. Additional water data were collected at various sites not involved in the systematic data-collection program and are published as miscellaneous measurements. These data represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Utah.

Hydrologic conditions for Utah can vary greatly across the State because of topography, geology, changing seasonal atmospheric conditions, and changes in climatic conditions from year to year. Mountain ranges and plateaus in many parts of Utah are characterized by steep slopes, sparse vegetation, thin soils, and, in areas such as the Colorado River Basin, large expanses of bedrock and steep-walled canyons. These conditions can lead to rapid runoff and flooding during much of the year. The large valleys and basins in the western part of Utah generally trend north, have a fairly flat topography, and are underlain with alluvial soils composed of clay, silt, sand, and gravel. Average annual precipitation in Utah ranges from about 5 inches in the Great Salt Lake Desert to about 60 inches on some of the State’s highest mountains (Butler and Marsell, 1972). Precipitation in Utah results from three general atmospheric conditions: Pacific frontal systems (late fall through early spring), cutoff low-pressure systems (late spring and fall), and monsoonal thunderstorms (summer). Frontal systems usually move west-to-east across Utah and account for much of the mountain snowpack (U.S. Geological Survey, 1991). These systems can affect all or part of the State, depending on the prevailing jet stream (high-altitude winds). Before reaching Utah, Pacific frontal storms must first cross the Sierra and Cascade mountain ranges, where a large part of the original precipitation falls as rain and snow. Therefore, the storms are relatively dry upon reaching Utah, resulting in comparatively light precipitation over most of the State (Utah Climate Center, 2003). During some winters, a high-pressure ridge is dominant over the Western United States, and the jet stream is forced north or south of Utah, resulting in winter drought. When conducive, weather systems moving across Great Salt Lake acquire additional moisture from evaporation of lake water, enhancing precipitation in the local area. This is the so-called “lake effect.”

Cutoff low-pressure systems generally originate in the Pacific Ocean, are widespread and slow moving, and can produce large amounts of precipitation over an extended time (U.S. Geological Survey, 1991). These are typically dissipating tropical cyclones, including tropical storms and hurricanes. One such storm in late-September 1982 resulted in a monthly record 7.04 inches of rain at Salt Lake City and 13.47 inches of precipitation (including 45 inches of snow) in the nearby mountains, at Alta. Monsoonal thunderstorms frequently occur during the summer months when high temperatures and heating of the Earth’s surface produce strong thermals. Subtropical moisture originating in the Gulf of Mexico and Gulf of California can combine with these thermals and produce locally intense thunderstorms.
