Prairie Band Potawatomi, Iowa Tribe urge formal tribal representation and protection of tribal water rights

The chairman of the Prairie Band Potawatomi Nation told the Kansas Water Task Force that tribal water rights predate the state and that the tribe has been seeking formal representation in state water planning.

"For Native Americans, water is central to us," the chairman said, noting decades of disruption to water quality and access on reservation lands. He said the nation occupies a 30-by-30-mile reservation established in 1846 and that recent U.S. Supreme Court decisions underscore that reservations remain in effect unless Congress disestablishes them.

Misty Slater, chairwoman of the Iowa Tribe of Kansas and Nebraska, told the task force the tribes lands span the Kansas-Nebraska border and that upstream agricultural runoff has led to persistent nitrate contamination, repeated boil-water advisories and additional costs for filtration systems. "These efforts, while necessary, impose additional financial burdens on our community," she said.

Stephanie Zarin, special water counsel to the Prairie Band Potawatomi Nation, told the task force the federal process to quantify and settle Indian water rights is typically multi‑decadal and resource‑intensive. Zarin said the absence of formal federal settlements does not negate tribal water rights under the Winters doctrine; she urged the state and tribes to continue cooperative, government-to-government monitoring and planning in the near term so tribal interests can be protected while settlements are pursued.

Task force members asked the tribal representatives for maps and acreage statistics and discussed how tribal land patterns and checkerboard ownership complicate oversight and regulation. Committee members encouraged tabling specific mapping requests for staff to follow up and recommended additional technical exchanges with the tribes.

Why it matters: Tribal water rights and Tribal-state federal relationships can affect allocation and planning for large surface and groundwater systems. Tribal speakers made three core requests: (1) formal, ongoing government-to-government consultation; (2) improved groundwater and aquifer mapping across reservation lands; and (3) better monitoring and funding to address water-quality problems that tribal leaders said already affect public health in some tribal communities.
