Water-budget or water-balance is a measurement of continuity of flow of water into and out of a specified boundary.It is analogous to one’s bank or business account.In practice, however, the evaluation of the water-budget elements may become quite complicated.

For this water-budget analysis, York County, an area of 575 square miles situated on a gently rolling upland plain in Southeast Nebraska, was selected. York County may be considered a well- defined political and geo-hydrologic unit because it exhibits not only distinctly identified geo-hydrologic conditions but also demonstrates some water supply problems such as overall declining groundwater table due to increasing water demand for irrigation and limited recharge conditions due to high clay content in the soils.This situation has been a great concern for the York County Groundwater Conservation District in recent years.A well oriented groundwater withdrawal investigation was initiated in 1968 by the Department of Agricultural Engineering, University of Nebraska, and is still underway by the U.S. Geological Survey Water Resources Division.

The results of the 1968-69 year water-budget analysis has indicated that there has been an average increase of 2.64 inches on the overall level of the groundwater reservoir.
