Update October 4, 2019

On October 02, 2019, monitors from Davis County Health Department observed a cyanobacteria bloom on Maybey Pond and sampled for cyanotoxins and cyanobacteria cell-counts.

Samples were delivered to UPHL for toxin analysis and to PhycoTech for cell identification and concentration. Cell count results are expected sometime next week.

Toxin results were delivered on October 03, 2019 and showed anatoxin-a levels of 0.13 micrograms per liter (µg/) from the elbow-depth sample. These levels are above the recreation health-based threshold for a Warning Advisory.

The Davis County Health Department (DCHD) issued a Warning Advisory on Maybey Pond on October 4, 2019.

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.
