This bill settles a long-running water rights dispute involving the Agua Caliente Band of Cahuilla Indians, a Native American tribe in California. The tribe has been fighting in court for years over how much water they're entitled to use from underground aquifers in their region. This settlement agreement brings all those lawsuits to an end by officially recognizing the tribe's water rights and establishing how much water they can use annually.

The settlement creates a trust fund to help the tribe develop water projects that improve their water supply and infrastructure. It also resolves disputes about various water-related fees and taxes the tribe has been charged. The bill authorizes the federal government to transfer some federal land to the tribe and to sell other federal land to the Coachella Valley Water District, a local water agency. Additionally, it addresses tax issues related to property on tribal lands.

The agreement involves three main parties working together: the Agua Caliente tribe, the Coachella Valley Water District, and the Desert Water Agency. By ratifying this settlement, Congress is officially approving the deal and providing the funding needed to make it work. This ends decades of legal conflict and gives the tribe a clear, legally recognized water supply for their reservation and community members.
