ST. GEORGE – In a statement prepared by the Washington County Water Conservancy District last week addressing the identification of quagga mussels in Lake Powell, the district took the position that the mussels do not jeopardize the proposed Lake Powell Pipeline and indicated that the project is on track for construction to begin around 2020. Following is the water district’s statement:
Utah Division of Wildlife Resources has positively identified quagga mussels in Lake Powell. Quagga mussels are an invasive species that has spread rapidly throughout the United States and can impact water supply infrastructure, including intakes and pipelines, as well as water quality and recreation.
This discovery does not jeopardize the Lake Powell Pipeline, a State of Utah project that will transport approximately 82,000 acre feet of water from Lake Powell to water users in Washington and Kane Counties via a 138-mile underground pipeline.
There are many chemicals and other approaches that have proven effective at controlling mussels in pipelines. Plans to prevent the infestation from spreading to other water bodies, including Sand Hollow and Quail Creek Reservoirs, will be included in the Lake Powell Pipeline plan.
The Lake Powell Pipeline is currently nearing the completion of several years of environmental studies. A preliminary record of decision is expected in 2016 and a final design in 2018. Construction is expected to commence around 2020.
Project developers expect additional control methods will be available when the Lake Powell Pipeline commences construction since research on quagga mussels is ongoing.
The State of Utah and water districts in Washington and Kane counties remain committed to providing a safe, reliable water supply for its growing populations.
