Summary
Background
A Nebraska corporation owns a canal that, since 1890, diverted water from the North Fork of the Republican River. About one-third of that water was used on Colorado lands and two-thirds was carried into Nebraska for irrigation. In 1913 the company sued Colorado state water officials, saying its 1890 appropriation gave it a right to carry and sell the water in Nebraska, and that Colorado officials were impairing that right by allowing others in Colorado to use or waste the water.
Reasoning
The main question was whether a prior appropriation made in Colorado to use water in Nebraska outranks later Colorado appropriations for use in Colorado. The district court found the company had a vested property right in the water at the Nebraska state line and enjoined Colorado officers from treating the company differently because the canal crossed the state line. The Circuit Court of Appeals agreed. The Supreme Court found the federal constitutional issue substantial, relied on the same principles announced in a related opinion, and affirmed the lower courts’ judgment protecting the company’s priority.
Real world impact
The ruling protects the company’s long-standing diversion into Nebraska and stops Colorado officials from cutting off or disadvantaging that diversion because of the state border. The decree was confined to this specific claim; other allegations about wasteful use or additional rights were left for separate proceedings. The decision enforces the company’s prior appropriation right in this interstate context.
