Class Spotlight - Water Genius (Continued)
From there, the group traveled down to Sand Hollow Reservoir in Hurricane, a critical facility because it not only stores water in the lake, it is also a groundwater recharge facility. Sand Hollow is intentionally designed to leak to allow the water to push down into the Navajo sandstone underneath and filter it so it can be stored as groundwater. Sand Hollow Reservoir holds about 50,000 acre-feet of water, but the underlying sandstone extends the storage capacity of the facility to about 200,000 acre-feet. To put the volume in perspective, the region’s water demands in 2025 were 53,000 acre-feet. The two reservoirs the group visited comprise the bulk of the municipal water supply in Washington County. If you didn’t get the chance to take his class this semester, there's good news - Doug will return with Water Genius this fall. For those that did take it, don't forget to share your water knowledge!
