Update October 7, 2021 (HABs)
Samples taken on 10/4/2021 were returned on October 6th. The sample from the day use area contained a toxigenic cell density of 12,650,618 cells/mL of Dolichospermum which is well above the UDWQ/UDOH recommended Warning Advisory threshold of 100,000 cells/mL. DWQ will continue to watch the reservoir closely.
Keep yourself and your family safe during waterborne pathogen contamination.
