Update October 11, 2019

Strawberry Reservoir, October 10, 2019

The Wasatch County Health Department (WCHD) issued a lakewide Warning Advisory on October 11, 2019, for Strawberry Reservoir after toxin test results from samples collected on October 7, 2019, by the Division of Water Quality (DWQ), exceeded the recreation health-based threshold for anatoxin-a at one sample site. Cyanobacteria cell-count concentration results are pending from PhycoTech, but satellite imagery indicates a lakewide bloom. Warning signs are being posted at all access points on the reservoir.

A Warning Advisory indicates a moderate relative probability of acute health risk, cell-count density of 20,000 – 10 million cells per milliliter (cells/ml), microcystin levels of 4-2,000 micrograms per liter (µg/L), or anatoxin-a levels above non-detect.
