Update August 6, 2021 (HABs)
Samples taken from the reservoir on August 3rd contained toxigenic cyanobacteria cell densities at 156 cells/m, which is well below the UDWQ/UDOH recommended Warning Advisory threshold of 100,000 cells/mL. Routine monitoring for HABs will continue monthly.
Update August 4, 2021 (HABs)
The Warning Advisory for Otter Creek State Park has been removed by the Central Utah Public Health Department.
Otter Creek reservoir has had two weeks of toxigenic cyanobacteria cell density results below the UDWQ/UDOH recommended Warning Advisory threshold of 100,000 cells/mL.
