The Colorado River basin is home to 26 federally recognized tribes in seven western states. Despite their long-standing rights to about 20% of the water that flows through the Colorado, many tribes are excluded from water management decisions and don’t benefit from basic water infrastructure and a secure supply of clean, safe water. The Ten Tribes Partnership is taking a seat at the decision-making table by building capacity among tribes to claim their right to water, establishing water leases, and helping restore the river’s health. Drawing upon a spiritual mandate to “ensure that this sacred water will always be protected and available” the tribes are working to “advance sustainable water management through collaborative decision-making.”
