Young, A.R., Burbach, M.E., Howard, L.M., Waszgis M.M., Lackey, S.O., Joeckel R.M., 2018, Nebraska Statewide Groundwater-Level Monitoring Report 2018. University of Nebraska-Lincoln, Conservation and Survey Division, Nebraska Water Survey Paper 86, (WSP-86) 8.5" x 11", full color, richly illustrated , 24 pp. The term “groundwater” has come to be all but synonymous with Nebraska. Nearly three-quarters of the total volume of the High Plains Aquifer lies beneath the State. Groundwater maintains our streams, our ecosystems, our people, and our vitally important agricultural economy. Nebraska’s total groundwater resource is vast, yet it is also vulnerable to natural and anthropogenic changes, necessitating a long-term commitment to wise management through informed decision making. Monitoring, studying, and reporting form the essential basis for such management and, ultimately, for meeting the myriad challenges presented by change. The personnel of the Conservation and Survey Division (CSD) are pleased to support wise groundwater management through the issuance of this report, a yearly continuation of a long-running series of water-resources reports and maps published by CSD. The information provided herein should be used to inform, educate, and guide the citizens of Nebraska regarding water resources. All Nebraskans need clean, abundant and accessible water to sustain our economy and way of life. Therefore, we must all partner in management as informed citizens.
