Quail Creek Reservoir closed Sept. 4-5 for chemical treatment

HURRICANE — Quail Creek Reservoir will be closed to public use Thursday and Friday for a chemical treatment to remove algae.  The water district’s municipal customers will receive treated water from Sand Hollow Reservoir during the treatment. Water quality and deliveries will not be affected.

“Treating reservoirs is necessary to protect and enhance our water quality,” Corey Cram, associate general manager for Washington County Water Conservancy District, said. “This treatment will help mitigate taste and odor issues, which may result from algae infested waters, and ensure we’re delivering a quality product to our users.”

A helicopter is scheduled to drop approximately 40,000 pounds of copper sulfate crystals into the water on Thursday.  Copper sulfate is classified as a general-use material by the U.S. Environmental Protection Agency and is frequently used as an algaecide in irrigation and municipal water systems.  The crystals are designed to sink to the depths of the water and eliminate algae.

Prior to the treatment, the water district’s dive team will identify areas in the reservoir with the highest algae concentrations for target drops.  The divers will monitor drop zones and the effectiveness of the treatment.

The water district has performed multiple chemical treatments on its reservoirs throughout the years; the last was in 2012 at Sand Hollow Reservoir.

The district’s other reservoirs, including Sand Hollow, will be open to the public for recreational activities during this treatment.
