Water Law Basics

Water Law Basics

"Water law," or the law of how one obtains and maintains water rights, cannot be simply stated and requires an understanding of common law legal doctrines, such as "prior appropriation," "beneficial use," and "riparian rights." In addition to the common law doctrines, there are numerous state statutes and administrative regulations, water law requires an understanding of Washington state court decisions which interpret the common law and statutes. Because of the complexity of the law on water rights, several opinions of the Washington State Attorney General's Office, issued to assist the state Department of Ecology in administering water rights permits, are also significant sources of information and interpretation of water law in Washington State.

It is important to remember that the case law continues to develop. For example, none of the articles listed below reflect the July 2, 1998, decision of the Washington State Supreme Court in Department of Ecology v. Theodoratus. The majority and dissenting opinions in this case also provide an excellent discussion of the history and legal doctrines of water law.

The following articles summarize the complex area of the law of water rights:
