 Ozarks Aquifer Minimize

The Ozarks aquifer is a large aquifer system (approximately 48,000 square miles) that spreads throughout parts of Kansas, Oklahoma, Missouri, Arkansas and a small part of Illinois. Recharge occurs mainly from precipitation. The karst features of the aquifer such as sinkholes, springs and cave systems are found throughout the aquifer system, providing critical habitat to a variety of threatened and endangered species.

Ozarks Water Quality and Quantity data were obtained from the USGS National Water-quality Assessment Program (groundwater and surface water quality), the USGS (groundwater and surface water quantity), and the National Climatic Data Center (precipitation). The stations in the figure below were used for the data analysis for Groundwater and Surface Water Quality and Quantity. Degradation of aquifer water quality and surface water quality, both in terms of water bodies that supply recharge to the aquifer as well as the springs and cave system that have surface water provided by the aquifer can lead to detrimental effects on species that rely on the aquifer for habitat. Declines in aquifer levels and surface water levels can effect flows in springs and caved, which threaten the unique biodiversity of these niche karst habitats. The data can be viewed in the Ozarks Aquifer Mapping Application.
