Conserved Water Statutes are state laws enacted by California, Montana, Washington, and Oregon to conserve water and allocate water resources to meet the needs of increasing demand for water in the dry lands where irrigation is or was occurring. These laws helps the states to dismiss the disincentives to conserve water and do so without damaging pre-existing water rights. Because any extra amount of water after applying water to a beneficiaries of the pre-existing water policies does not belong to the appropriators, such a condition creates an incentive to use as much water as possible rather than saving. This obviously causes costs of irrigation to be greater than the optimal amount which makes the policy very inefficient. However, by enacting Conserved Water Statutes, state legislatures are able to address the disincentives to save water. The policy allows the appropriators to have rights over the surplus water and enforces them to verify their water savings by the water resources department. Out of the four states that adapted the Conserved Water Statutes, Oregon is often renowned to be the most successful. According to "How Expanding The Productivity of Water Rights Could Lessen Our Water Woes," The Oregon Water Resources Department (OWRD) has been a success because a high percentage of submitted applications submitted, and the OWRD serves as a good intermediaries that help appropriators to conserve water. OWRD’s programs are not only a success because its effectiveness but also because of their efforts to improve the workers’ working conditions. According to OWRD's website, the state policies regarding the water rights are divided into Cultural Competency, Traditional Health Worker, Coordinated Care Organizations, and Race, Ethnicity and Language Data Collection.
