In many areas of the United States, excessive pumping and groundwater overdraft are causing rivers and wetlands to go dry. In western states, where most surface water has long been fully appropriated, growing populations have turned increasingly to groundwater, leading to decreases in streamflows, conflicts with surface water rights, and harm to fish and wildlife. States have begun the process of reforming outdated laws and policies, some more ambitiously than others, and with mixed results. In this talk, we will look at the experience of Oregon, New Mexico, and Texas, and explore steps that states have taken to limit groundwater pumping while avoiding undue harm to regional economies. We will also examine the role of discuss the role of the endangered species protections, environmental organizations and water trusts in precipitating these changes. Further, we will explore how states used tools such as basin closures; groundwater rights, mitigation, and water markets to promote sustainable water use. We will conclude by looking at what else states should be doing to manage groundwater and surface water conjunctively, as a single resource, to promote a healthy environment and healthy economies.
