Fluctuations of ground‐water levels in Utah

Long‐time continuous records of the fluctuations of ground‐water levels have been obtained at relatively few locations in the United States. Among the few available records for Utah that extend continuously over a period of a year or more are those made in the Jordan River and Ogden valleys by the United States Geological Survey in cooperation with Salt Lake City and Ogden. A few of the records of water‐levels, with records of stream‐flow and precipitation, are shown in Figure 1. Most of these records were begun during 1931 or 1932. A State‐wide program of well‐observations was begun during the summer of 1935 and is now in progress, the work being done by the Geological Survey in cooperation with the Utah State Engineer.
