Eastern ASA Hydrology Study
Oklahoma's landowners and other stakeholders have worked to preserve the Arbuckle-Simpson’s water supply and promote economic growth through sustainable water practices. Based on those needs, Oka’ is facilitating an interest-driven study.
The Eastern ASA Hydrology study is a five million dollar study to be conducted over an eight-year time period. This study will build on the Phase One study which determined the maximum annual yield for the Arbuckle-Simpson Aquifer.
This project will be comprised of three parts. The first two steps will be the concentrated monitoring of springs, streams, wells and a look into the hydrological framework. Lastly, the data collected will be compiled to create a hydrological model for the aquifer.
With the advancements in the technology of hydrological modeling, we expect this study to be of the highest quality. This data will serve as the definitive tool for all stakeholders who rely on this aquifer for water.
Lake of the Arbuckles Watershed Association
The Lake of the Arbuckles and the Chickasaw National Recreation Area provides enormous economic benefits to Oklahoma. In addition to serving as a vital water supply for area citizens, associated recreational opportunities and more than 1.5 million annual visitors contribute some $12.7 million to area economies.
Growing water demands and increased activity in the watershed have begun to impair the quantity and quality of lake waters. The Lake of the Arbuckles Watershed Association (LAWA) was created by landowners to collaboratively work on land management practices that benefit the watershed and restore the Lake of the Arbuckles quality. With the support of the Chickasaw Nation and the Oka’ Institute at East Central University, LAWA works proactively to protect and address local issues
Lake Texoma Watershed Alliance
Lake Texoma Watershed Alliance (LTWA) is an interstate group of members from Oklahoma and Texas who share a desire to protect, preserve, and improve the watershed surrounding Lake Texoma to promote its extensive benefits. The LTWA Steering Committee recognizes that a healthy watershed is essential to the health of Lake Texoma and the region. The Lake Texoma Watershed is a resource of critical importance to Oklahoma and Texas.
Improving water quality
Promoting community sustainability
Balancing responsible water use
Restoring water functionality across the basin
Aquifer Storage and Recovery (ASR) has been studied and implemented at many locations around the nation. Enhanced Aquifer Recharge is a unique application of ASR, focused around a rural landscape management approach to enhance natural infiltration process and re-purpose storm flow to groundwater and baseflow enhancement.
The City of Ada is partnering with the Chickasaw Nation, Oka’ the Water Institute at East Central University and Oklahoma State University looking at EAR as a cost-effective way to preserve the city's water supply.
Other cities have projects in place to treat water supply and return it to the ground for later use. A water treatment plant, installing pipe and other equipment for this kind of water reuse is too expensive for a small city like Ada. An alternative is E.A.R.
The Robert S. Kerr Environmental Research Center has provided technical assistance and the city has installed small leaky pond structures connected to naturally occurring faults in the Arbuckle-Simpson Aquifer to capture rainstorm runoff. This runoff should go back into the aquifer to recharge and enhance streams and springs flow.
