Tribes that rely on Colorado River water — and the complex set of rules that govern it — are worried about how President Donald Trump’s executive orders and the ongoing legal questions about them will affect their water access. President Trump froze federal funds for the Inflation Reduction Act. Even after a judge reinstated those funds, tribes are concerned about the viability of some water conservation efforts going forward. Those water access issues are becoming increasingly important because of long-term trends showing significantly less water available in the basin.
