Coal Creek: More Than a Scenic Creek
For many people, Coal Creek is one of Cedar Valley’s most recognizable landmarks. It winds through Cedar City, providing beautiful scenery and a reminder that our water begins high in the mountains. But Coal Creek does much more than add to our landscape, it plays a vital role in Cedar Valley’s water system.
Each spring, snowmelt from Cedar Mountain flows into Coal Creek, beginning a journey that supports farms, replenishes our aquifer, and helps provide water for our community. Unlike a major river that flows for hundreds of miles, Coal Creek is a creek with a limited watershed that eventually comes to an end. That means every drop of water is valuable, and Cedar Valley has developed innovative ways to make the most of this precious resource.
As the water travels downstream, some naturally seeps through the creek bed and into the ground, helping recharge the Cedar Valley aquifer. But the journey doesn’t stop there. Much of Coal Creek’s water is carefully managed to support agriculture, groundwater recharge, and water reuse projects that allow this limited water supply to benefit the community more than once.
Water That Works More Than Once
As Coal Creek flows through the valley, much of its water is diverted to irrigate local agricultural fields. That water helps grow crops that support our community and local economy.
When runoff exceeds immediate irrigation needs, Cedar Valley Water Conservancy works with partners to capture and put that excess water to work instead of letting it go to waste.
Some of the excess flow is directed into managed recharge basins, where it slowly filters through layers of soil and gravel before replenishing the Cedar Valley aquifer. This process, called managed aquifer recharge, helps restore groundwater supplies.
Giving Water a Second Purpose
Historically, water flowing into Quichapa Lake had elevated levels of total dissolved solids (TDS), making it unsuitable for culinary use. As the water sat in the lake, evaporation concentrated the dissolved minerals, causing TDS levels to continue rising while the water itself slowly disappeared. What was once a resource with limited use was eventually lost to evaporation. Today, the Quichapa Recharge Project has changed that outcome by capturing and repurposing this water to support agriculture, recharge the aquifer, and reduce groundwater pumping, turning a previously underutilized resource into part of Cedar Valley’s long-term water strategy.
The project diverts cleaner excess water into a specially designed “lazy river” where sediment can settle out naturally. From there, the water can either be pumped into a nearby agricultural fields for irrigation. When the farmer uses this surface water, they can idle their groundwater wells, reducing groundwater pumping and helping preserve the aquifer for culinary use.
Every Drop Has a Purpose
Coal Creek is more than a beautiful place to visit. It is part of a carefully managed water system that combines nature with innovative infrastructure. From mountain snowpack to agricultural irrigation, groundwater recharge, and water reuse, each step helps maximize one of Cedar Valley’s most valuable resources.
Projects like the Quichapa Recharge Project, and the recharge basins demonstrate how thoughtful planning can take water that was once lost to evaporation and put it back to work—supporting agriculture, replenishing the aquifer, and helping secure a reliable water supply for future generations.

What Is an Aquifer?
An aquifer is a natural underground layer of sand, gravel, and rock that stores groundwater. Think of it as a giant underground reservoir that supplies water to homes, businesses, farms, and communities throughout Cedar Valley.
Unlike a lake or reservoir, you can’t see an aquifer, but it is one of our valley’s most valuable natural resources.
Did You Know?
Much of the water that falls as snow on Cedar Mountain eventually makes its way through Coal Creek, where some of it naturally filters into the ground and helps replenish Cedar Valley’s aquifer. Nature has been recharging our water supply long before modern infrastructure existed.
