What is CPASA?

CPASA grew out of a grassroots effort in 2002 when local citizens acted in response to man-made threats to the Arbuckle Simpson aquifer and the springs and streams which flow from it. CPASA supports sustainable use, not a "use it all up" policy, the oil/gas model used for Oklahoma's groundwater law.

Our membership has spread throughout Oklahoma and other states as people have learned about our efforts.

  • CPASA recommends SB288 implementation strategy to OWRB

    Following a review of the conclusions drawn by OWRB after the 5-year study was completed, CPASA is making its recommendations for implementation of SB288. Highlights of the document: (1) Support for maximum annual yield not to exceed 25K-30K acre ft/yr with equal proportionate share of 1.5 acre in/yr; and (2) Applicant must show 20% or less impact on springs and streams.

  • Arbuckle-Simpson aquifer study confirms worst fears

    Large-scale pumping of groundwater would have depleted area springs and streams

    The attempt by a group of communities based in Canadian County to pump more than 80,000 acre feet of water from the Arbuckle-Simpson aquifer and transport it to central Oklahoma in 2002 would have depleted area springs and streams if allowed to proceed, a study recently completed by the Oklahoma Water Resources Board reveals.

    Passage of Senate Bill 288 in 2003 established a moratorium prohibiting any municipality or other political subdivision outside the Arbuckle-Simpson basin from entering into a contract which would lead to municipal or public water supply use of groundwater from the basin. The moratorium has remained in effect since that time until the present comprehensive study of the aquifer conducted by the OWRB could be completed.

    Results of the Arbuckle-Simpson aquifer hydrological study were summarized during an informal public meeting August 18 at the Pontotoc Technology Center in Ada.

THE BLUE RIVER
One of Oklahoma's most beautiful rivers, the Blue River begins near Connerville in Johnston County and flows southeasterly to the Red River. The river is spring-fed and has designated trout fishing areas. You can also fish for black bass, channel and blue catfish and crappie. Learn more about Blue River here

THE ARBUCKLE SIMPSON AQUIFER
Arbuckle Simpson Watershed
The Arbuckle Simpson aquifer lies beneath a surface area of about 500 square miles (320,000 acres) in south-central Oklahoma. Nobody knows how deep it really is, but the lower portions of the aquifer are more than 1,000 feet deep and it may be 4,000 feet deep in some places. It is estimated to contain around 9 million acre-feet of water (one acre-foot equals 325,851 gallons).

Almost 100 springs are known to discharge water from the Arbuckle Simpson aquifer. The water comes out of the ground clear and chilled to about 54 to 57 degrees, year round. In turn, these springs create creeks and rivers which, without the springs, would stop flowing.

Several of the larger springs create streams with constant flow, such as the Blue River and Delaware Creek, which flow into the Red River, and Mill, Pennington, Honey, Hickory, and Oil Creeks, which flow into the Washita River. Numerous commercial, recreational, municipal and federal facilities rely on the waterways fed by spring flows of the Arbuckle Simpson aquifer.
