Ramsey notes that the primary driver of this drought stage is the San Juan River flow in conjunction with the U.S. Drought Monitor, which indicates our area is in a severe to moderate drought.

Ramsey notes that PAWSD is continuing to request voluntary odd/even watering days, “requesting that if your address is an odd number only irrigate on odd calendar days and vice-versa for even number addresses.”

There are no other mandatory water use restrictions in place, besides limiting irrigation to after 6 p.m. and before 9 a.m.
