USDA Announces Funding for Ogallala Aquifer Through the Natural Resources Con- servation Service (NRCS), the U.S. De- partment of Agriculture on May 14 announced $6.5 million will be invested to improve the water quality and quan- tity in the Ogallala aquifer region. The work will be focused on seven issue areas in five states, and funding will be used to install sensors and weather stations as well as promote new technologies to allow for more efficient irrigation. This is the fifth year for the NRCS' Ogallala Aquifer Initiative. The initiative supports funding and awareness for one of the nation's princi- pal aquifers, which supplies water for one-fifth of the nation's corn, wheat, and cattle growers. The initiative will support important preservation of this resource, ensuring it can continue to be a water supply for citizens and the agri- cultural community. USGS Research Assesses Minnesota's Groundwater New research could help water re- source managers quantify critical groundwater resources and assess the sustainability of long-term water use in Minnesota. U.S. Geological Survey scientists re- cently estimated annual rates of poten- tial recharge, or the natural replenishment of groundwater, over 15 years across Minnesota. According to the study, the statewide mean annual po- tential recharge rate from 1996-2010 was 4.9 inches per year. Recharge rates increased from west to east across the state and April generally had the highest potential recharge. Improved estimates of recharge are necessary because nearly 75% of drink- ing water and 90% of agricultural irriga- tion water in Minnesota are supplied from groundwater. "Resource managers in Minnesota can use this study to help inform water use or water conservation guidelines throughout the state," USGS scientist and the report's lead author Erik Smith said. To maintain a stable supply of groundwater, recharge rates must be high enough to compensate for water that is lost to streams, lakes, and other surface water bodies, or removed for uses such as agriculture. The scientists used data about daily precipitation, min- imum and maximum daily temperatures, land cover, and soil to model Min- nesota's recharge rates. During the study period, mean an- nual potential recharge estimates across Minnesota ranged from less than 0.1 to 17.8 inches per year. USGS partnered with the Minnesota Pollution Control Agency on the study.
