Washington v. Oregon
Headline: Interstate water fight ends with Court dismissing Washington’s suit and allowing Oregon farmers to keep long-standing river diversions, while rejecting Gardena Farms’ delayed priority claim and leaving local irrigation unchanged.
Holding:
- Allows Oregon farmers to keep long-standing water diversions near Red Bridge.
- Prevents Washington from getting an injunction to force more water downstream.
- Finds Gardena Farms’ 1892 claim forfeited for lack of timely use and diligence.
Summary
Background
The State of Washington sued, saying people in Oregon were wrongfully diverting the Walla Walla River above Red Bridge and harming Washington users downstream. Oregon farmers had for decades diverted the Tum-a-lum branch into the Little Walla Walla, and Oregon residents also pump many wells. Washington’s complaint also challenged a Gardena Farms claim to an 1892 water priority intended to supply a canal in Washington.
Reasoning
A Special Master took evidence and found the Oregon uses were long established, reasonable, and not unduly wasteful. The Master found that water turned past Red Bridge would mostly sink into deep gravel and not reach Washington users, and that pumping from wells was used on the overlying farms. The Master also concluded Gardena Farms had not diligently put the claimed 1892 priority to beneficial use and had effectively abandoned it. The Court accepted these findings and emphasized that a state asking for equitable relief must prove clear and convincing injury of serious magnitude.
Real world impact
Because Washington failed to meet the heavy proof burden, the Court dismissed the suit and left the Oregon diversions and well-pumping in place. Gardena Farms’ claimed 1892 priority was not enforced because of delay and lack of use. The decision preserves the status quo for local irrigation and splits the costs of the litigation between the states.
