Update July 19, 2020
The Jordan River in Lehi is under a Health Watch after a Utah State University Water Watch volunteer observed a harmful algal bloom there on July 18, 2020. The Utah County Health Department, Salt Lake County Health Department, and Salt Lake City Public Works have been notified. The Division of Water Quality (DWQ) plans to sample the area within the next seven days.
A Health Watch is not a formal advisory level but rather an indicator that a bloom may exist or become more severe based on available information from DWQ and the Department of Health. Indicators can include visual reports.
