Deep Pond in Tucson, Ariz., has quickly shrunk from its normal six acres wide to approximately four acres. The pond has dwindled to unusually low amounts due to a prolonged drought in the region. According to Jennifer Becker, principal hydrologist of the Regional Flood Control District, the last measurable inflow was Aug. 13, 2017.

“The Deep Pond is our storm water savings bank,” said Becker to the Arizona Daily Star. “Its primary function is storm water storage.”

The storm water stored in the pond is primarily used for irrigation and is a major part of the Kino Environmental Restoration Project. In the meantime, Becker and other members of the Tucson Regional Flood Control District are hoping for rain to provide the basin with much needed revitalization.
