Groundwater levels in the Ogallala Aquifer declined far less last year then they did in 2013-14, a study showed.
Annual water level measurements indicate an average decline of -0.56 of a foot in the level of the aquifer within the 16-county High Plains Underground Water Conservation District No. 1 service area from 2014 to 2015.
The decline is 0.76 of a foot less than the -1.32 feet drop recorded in 2013-2014 during continuing drought conditions.
The 10-year average change (2005-2015) was -10.27 feet while the five-year average change (2010-2015) was -5.69 feet.
