The May 2021 issue of Discover Magazine included an article, These Wetlands Feed The Largest Aquifer In The U.S. What Happens If We Lose Them?, which highlights the importance of playas to groundwater recharge.
Playas are a primary source of groundwater recharge, with an average rate across the region of about three inches per year.
Playas are water filtration systems—keeping fertilizers, herbicides, and pesticides out of the groundwater.
Playas attract wildlife, providing local waterfowl and upland game bird hunting and wildlife viewing opportunities.
Playas collect runoff during high rains, reducing property damage from flooding and reducing erosion.
