Wisconsin's water-monitoring network is in danger of losing critical ground-water, surface-water, and water-quality monitoring stations. Since 1995, the ground-water network has decreased by 43 observation wells, the surface-water network by 7 stations, and the surface-water- quality network by 30 stations. Reductions in Wisconsin's water-monitoring network could cause serious risk to the residents of Wisconsin. This reduction increases the uncertainty of water-resource plans and decisions, which ultimately could increase the potential for damages from extreme events and increase construction costs of water-related facilities.
