Stream flow and snowpack levels have some farmers concerned as to what this might mean to their irrigated crops and access to water later this summer. As we are well into the irrigation season, it is a good time to review how Oregon water law works.
Oregon water laws date back to 1909 when state control over the right to use water began. In Oregon, all water is considered publicly owned and with only a few exceptions, water users must obtain a permit or water right to use water from any source, whether underground or from streams and rivers. Prior to 1909, water users had to personally defend their rights to water or turn to local courts.
Quotes referring to the conflicts over water in the Western region of the United States can be found throughout history. From a somewhat famous quote rumored to be from Mark Twain, “Whiskey is for drinking; water is for fighting over” to citing former Arizona senator, Barry Goldwater, “A man from the west will fight over three things: water, women, and gold, and usually in that order.”
To establish order in Oregon, here are the four basic provisions of the water code:
- Beneficial use without waste. There are many demands on Oregon’s water resources including a wide array of beneficial uses. Irrigation for crops is just one. Water is needed for domestic use for people and animals, city drinking water, and industrial uses like manufacturing, and some water must also remain available in-stream for fish and other aquatic life.
- Appurtenancy. A water right is attached to the land described on the water right certificate and final proof map, as long as the water is used. If the land is sold, the water right goes with the land to the new owner.
- Must be used. A water right needs to be used as provided in the right at least once every five years. After five consecutive years of non-use, the right is subject to cancellation.
- Priority. The water right priority date determines who gets water in a time of shortage.
The Oregon Water Resources Department (OWRD) regulates water laws, including water rights. On an average year, Watermasters in Western Oregon may begin placing restrictions on junior right holders in late August and September if water flow does not meet demand. Michael Mattick, Watermaster, District 2 which includes Lane and Linn Counties says that in his area “it is too early to tell if flows will drop off or not. A little periodic rain this summer could mean no regulation is necessary.”
