Water is the planet's most precious natural resource. Deciding how it will be shared among competing demands is one of a society's most challenging questions. Water Resources Law is a review of the law and policies concerned with the allocation of water resources in the United States. This course will examine the three main systems of water law in the United States: Eastern riparian systems, the prior appropriation doctrine of the West, and the nationally diverse laws regulating the use of groundwater. The course will also review federal water allocation issues, interstate water disputes, tribal water rights matters, and will highlight contemporary water allocation dilemmas throughout the country.
