- HAB Cyanobacteria Cell Count (October 25, 2017, Excel)
Update November 6, 2017
The Division of Water Quality (DWQ) collected a sample at Haws Point on Strawberry Reservoir on October 25, 2017, after the DEQ Spill Line received a report of a cyanobacteria bloom in the area. Toxigenic cyanobacteria cell-count concentrations were greater than 256,000 cells per milliliter (cells/ml). These cell-count densities exceed the 20,000 cells/ml threshold for a warning advisory under UDOH-UDEQ health-based guidance. The dominant taxon was Aphanizomenon at 254,275 cells/ml. Other taxa present in very small quantities included Aphanocapsa, Aphanothece, and Synechocystis. Aphanizomenon is a potential toxin producer for microcystin, anatoxin-a, and cylindrospermopsin. Synechocystisis and Aphanocapsa are potential toxin producers for microcystin.
Toxin strip tests on the October 25, 2017, sample were non-detect for microcystin and detect for anatoxin-a. A confirmation sample was sent to the Utah Department of Agriculture and Food (UDAF) for ELISA testing for anatoxin-a levels. UDAF results were non-detect for anatoxin-a.
The bloom appears to be isolated to a few shoreline areas.
