Over the past few years, there has been a growing awareness of playas and their role in recharging the Ogallala Aquifer, including published articles.
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.
“Not only do playas contribute to recharge, they dominate recharge. During the early minutes of a rain inundation, water flows through cracks in the clay soil and into the zone just beneath the playa floor. These cracks, which form when the playa runs dry, can slice as deep as 3 feet. They facilitate water flow into the clay subsurface at rates up to 116 inches per hour.”
