Washington County Conservancy District is looking at the future of Washington County through the year 2040, Morgan Jensen, Conservancy District spokesman said.
A 1994 Boyle Engineering Co. study offers three areas of focus: population projections and future water demands; water development project identification; and project summaries and rankings.According to the study, the current water supply to the residents of Washington County would be inadequate by the year 2010.
To continue providing for the water needs of the county, the Conservancy District has proposed thirteen projects.
A stream simulation model was used to evaluate the addition of three water resources to the Virgin River: Sand Hollow Reservoir, Ash Creek Tributary Diversion Project, and the diversion of LaVerkin Springs (Pah Tempe) below the Washington Fields Diversion Dam.
Ranking of projects indicated Pah Tempe to be the most cost-effective, Sand Hollow was rated highest in non-cost issues and Ash Creek was considered relatively expensive, but also ranked high in non-cost issues, the Conservancy District said.
Other projects considered feasible were piping Santa Clara River water from Gunlock Reservoir to Ivins Reservoir and ground water development and a pipeline from Lake Powell to St. George.
These studies and projections are a valuable resource to the Water Conservancy District as they plan to meet growth and provide for present Washington County needs, Jensen said.
The conclusion of the present studies indicate that if each of the above projects were to be completed, the water needs of the county would be covered beyond 2040 under low growth and until at least 2025 under a high growth rate.
For those who would like more information on water needs in Washington County and projections on how these needs can be met, copies of the study are available at the Washington County Conservancy District office in St. George.
