The wetter water year for Tooele County continued in March, causing the U.S. Drought Monitor to lift its drought designation from nearly all of Tooele County.
Only 3.2% of the county remained in a drought condition as of April 2, according to the U.S. Drought Monitor.
The area of Tooele County remaining in drought is so small it doesn’t show up on the Drought Monitor’s map. According to the monitor’s statistical table, nobody lives in the area.
The western part of Tooele County, comprising 63% of the county, is designated as no drought. The eastern part of Tooele County, consisting of 33.8% of the county, is designated as drought level zero, a level not considered as a drought by the U.S. Drought Monitor. It is a designation used for areas showing dryness but not yet in drought, or for areas recovering from drought.
Tooele County’s pattern of increased precipitation for the water year was part of a statewide trend, according to the National Resources Conservation Service’s March Utah Climate and Water Report.
“Drought conditions continued to improve across the state in March. … Looking ahead to the wet pattern predicted, drought conditions are likely to continue to improve in April,” reads the NRCS report.

SNOTEL, or snow telemetry, are remote battery powered sites across western mountains that automatically measure and transmit information about snow depth, water content, rainfall and air temperature. They are managed by the USDA’s National Resources and Conservation Service.
