Rules & Regulations

The Three Sisters Irrigation District is a quasi-governmental corporation, a political subdivision of the State of Oregon, duly organized and operated under Oregon law governing irrigation and other special districts. Special districts are governed by a variety of Oregon statutes and administrative rules; more specifically, Chapter 545 of the Oregon Revised statutes addresses the operation of irrigation districts. In addition, an entire body of law and custom has developed around the question of access to water in Oregon’s streams and the water rights attendant to that access.
