Water Level Declines in the High Plains Aquifer
June 9 | USGS
USGS has released a fact sheet that contains interesting maps and data documenting water level declines in the High Plains Aquifer. This important aquifer underlies over 100 million acres in Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas and Wyoming. Water levels in the aquifer have been in decline since it was first tapped for irrigating crops. Enormous declines - often over 150 feet (pre-development to 2005) - have been measured in many areas. This is a short report in .pdf format and worth a look just to see the maps. Reference: USGS Fact Sheet 2007-3029, Changes in Water Levels and Storage in the High Plains Aquifer, Predevelopment to 2005.
