BLM Western States Water Laws banner

This website reviews the water laws of eleven western states (Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, and Wyoming). Special attention is paid to the states’ water rights systems, the application processes, groundwater regulations, the general adjudication processes, and the states’ instream flow programs. Where information is available, comment is made on how the states handle federal reserved water rights and on other BLM specific information.

The purpose of this website is to provide a comprehensive water quality law summary for the Bureau of Land Management (BLM). The website includes a detailed examination of federal statutes including the Clean Water Act, the Coastal Zone Management Act, and the Oil Pollution Act. It also examines how each western state implements these federal acts and discusses additional state water quality laws applicable to BLM.
