[6] In 2014, the Mammoth Community Water District (MCWD) sued the Great Basin Unified Air Pollution Control District (GBUAP) and ORNI 50 LLC (Ormat) over concerns that the power plant would compromise the water supply of Mammoth Lakes.

GBUAP and Ormat disputed this, arguing there was no connectivity between the deep geothermal reservoir and MCWD's groundwater aquifer based on extensive research conducted on the site.

The dome was formed from the swelling or rising of the caldera floor due to movement in the magma chamber beneath it.
