• What is the difference between the riparian doctrine and prior appropriation?
Definition
Riparian Doctrine: For the, ‘wet,’ eastern states. Ownership of land along water determines right to ‘reasonable’ use of water. During a shortage all water users decrease use. Live adjacent to water have rights to it.
