A decades-long conflict over Missouri River water management has intensified between Missouri and North Dakota, stemming from North Dakota’s ambitious pipeline project. This initiative aims to divert water from the Missouri River basin into the Sheyenne and Red Rivers, ultimately flowing into Canada. The diverted water is intended to bolster municipal drinking water supplies and support irrigation efforts across central and eastern North Dakota.
North Dakota’s Justification and Investment
North Dakota officials defend the pipeline project by referencing unfulfilled federal promises made in the 1940s. They also emphasize the project’s necessity in protecting communities from drought. The state has already committed $400 million to the endeavor, with further investments anticipated. This project is seen by North Dakota as a crucial step to ensure water security for its growing population and agricultural needs.
Missouri’s Concerns and Legal Stance
Missouri, however, views North Dakota’s actions as setting a perilous precedent for future out-of-basin water diversions. This concern is amplified by the severe water shortages currently impacting western states, which may increasingly look to the vital Missouri River as a potential source. Missouri officials have voiced significant worries about the potential negative consequences for their state, including adverse effects on agriculture, utilities, public water supplies, power plants, and river navigation due to anticipated reductions in water levels.
In response to these concerns, the state of Missouri enacted a law in 2025 designed to regulate water exports. This legislative move underscores Missouri’s commitment to safeguarding its water resources against potentially detrimental diversions.
Path Forward: Dialogue and Legal Hurdles
Both Missouri and North Dakota acknowledge the pressing need for enhanced discussion and coordination regarding water management. This recognition comes despite a history of disagreements on collaborative efforts. A recent meeting held in Kansas City in March provided a platform for stakeholders from both states to engage in initial talks aimed at finding common ground.
A significant obstacle to reaching a comprehensive agreement lies in the fundamental differences between the two states’ water laws. Missouri operates under the eastern riparian law doctrine, which grants water rights based on land ownership along a watercourse. In contrast, North Dakota adheres to the western prior appropriation doctrine, commonly known as “first in time, first in right,” which prioritizes water rights based on the order in which they were established.
