The Agua Caliente Band of Cahuilla Indians has filed a second lawsuit against the Coachella Valley Water District and Desert Water Agency over groundwater.

The first lawsuit filed by the tribe against the districts over rights to groundwater access has been pending since 2013, however courts have already agreed with the tribe's contention that it has a reserved right to groundwater from the aquifer below reservation. In the new complaint filed on Jan. 24, the tribe asserts that it and its members should not have to pay a "replenishment assessment charge" for groundwater production on land owned by the tribe and individual tribal members.
