Each spring, the staff of the Upper Big Blue Natural Resources District takes measurements to determine the change in the groundwater level after it has rebounded from the previous season's irrigation use. You can examine individual years or watch the video below to see how the water levels have changed in the district from 2007 to the present. New data is added annually in May.
