Texas Water Development Board Needs Volunteers for Playa Monitoring Network
Playas are a major source of recharge to the Ogallala Aquifer and an important part of the High Plains ecosystem. According to satellite mapping, there are about 20,000 playas in Texas, with most of them located in the Texas Panhandle. Currently there are no comprehensive programs to monitor how much water is collected in these playas or to measure how much water goes to recharge and how much is lost to evaporation. "There‘s been a tendency to dismiss recharge to the Ogallala as unimportant because the half inch or so per year of recharge is small compared to annual pumping, but with long-term projections pointing to water shortages in much of the High Plains, every bit counts," says Weinberg. "Monitoring the playa lakes is the first part of a TWDB project to look at ways to increase recharge. In fact, it may even be possible to increase recharge while improving playas wetland function, but no one has tested that. We’re going to do that, but first we need better data on the way the playas function right now." Landowners who have one or more playas on their property are encouraged to contact the Texas Water Development board or their local groundwater conservation district to learn more about the Adopt-a-Playa Program. Once enrolled, TWDB staff will conduct a topographic survey of the playa basin and install a weather station and depth gauge in the playa. The landowner will then maintain the equipment, record playa depths and send monthly results. TWDB is taking applications throughout the summer and will begin installing equipment in the fall.

"First of Its Kind" Outdoor Playa Classroom Opened on June 8
"This classroom is the first of its kind and will provide a valuable learning experience for many teachers and students, or anyone interested in playas," says Julie Boatright, a Heritage Management graduate student at Texas Tech University and Intern for Ogallala Commons. Boatright, who designed the exhibit and classroom space, worked with playa experts to give classroom visitors a way of understanding what playa lakes are and why they are important. "Playas in this region are unique and essential to the region’s ecological health as well as serving as the main recharge to our dwindling Ogallala Aquifer. Plants, animals, and people in the region interact with playas on a daily basis," says Boatright. "Without them, biodiversity and quality of life would be reduced." Despite the key role of playas in the region, many people don’t know what playas are or what they do. That’s where the Outdoor Classroom will help. The 800-square foot open-air classroom features five interpretive panels describing key facts about playas, illustrations of playa plants, birds, and amphibians, as well as bench seating for 30 people, a work table, and two 1000-gallon rainwater collection tanks that store water harvested from the classroom roof.
The goal was to make a playa classroom template, one that any school could follow. The project was completed in phases, with each phase funded by grants. "The classroom was a costly project, but there is funding available," says Boatright. "You just have to get out there and ask questions until you find the grants." After doing just that, Ogallala Commons can provide tips and resources to schools or organizations that are interested in creating a similar outdoor classroom. According to Boatright, building partnerships with local resources was also a major part of their success. "Find people and organizations in your area who are already working with playas — like Natural Resources Conservation Service (NRCS), U.S. Fish & Wildlife Service (USFWS) and even birding organizations or enthusiasts." Funding and technical support for constructing the playa classroom was provided by Ogallala Commons, USFWS, Dixon Water Foundation, Playa Lakes Joint Venture, NRCS, and Texas Parks & Wildlife Department. Boatright also worked with local landscape architect Jason Hodges to develop the prairie landscaping, parking and paths around the classroom.
Help Educate Stakeholders about the Relationship Between Playas and the Ogallala Aquifer
To address these questions and concerns, the U.S. Geological Survey, in cooperation with the Playa Lakes Joint Venture, present a review and synthesis of the more than 175 publications about recharge rates and chemistry beneath playas and interplaya settings. Although a number of questions remain regarding the controls on recharge rates and chemistry beneath playas, the results from most published studies indicate that recharge rates beneath playas are substantially (1 to 2 orders of magnitude) higher than recharge rates beneath interplaya settings. The synthesis presented here supports the conceptual model that playas are important zones of recharge to the High Plains aquifer and are not strictly evaporative pans. The major findings of this synthesis yield science-based implications for the protection and management of playas and ground-water resources of the High Plains aquifer and directions for future research. We need your help to get this important information into the hands of farmers, ranchers, irrigators, and other stakeholders in the Southern High Plains. Please contact us to request copies of the four-page executive summary that includes the abstract, introduction and summary of major findings. For those who want more information, we can also provide copies of the full 37-page literature review and synthesis. To order copies of the executive summary or the full publication, contact Misti Vazquez, PLJV Communication Director, at 719-488-4460.
