Ross Reservoir is a 1 million gallon potable water storage facility that was built in 1927. It currently provides treated water for approximately 20 percent of MMWD's service area. The reservoir is located on a hillside north of Phoenix Lake.
A substantial landslide in the watershed is threatening to undermine Ross Reservoir. The purpose of the Ross Reservoir Landslide Repair Project is to stabilize the landslide and remove the threat it poses to Ross Reservoir and the surrounding area.
