2015 Water Supply & Drought Information - please click below for the following...


Normally, one full business day advance notice will be required for water orders, however, the District reserves the right to postpone water delivery orders two full business days when necessary.  7:00 a.m. is the cutoff time because Roza's Watermaster submits orders to the Bureau of Reclamation at 7:00 a.m.


For example: Water orders received by the District before 7:00 a.m. on a Tuesday will be delivered Wednesday.  Orders received after 7:00 a.m. Tuesday (but before 7:00 a.m. Wednesday) will be delivered Thursday.

Similarly, orders received before 7:00 a.m. Friday will be delivered Monday and orders received after 7:00 a.m. Friday will be delivered Tuesday.

Saturday, Sunday and holidays are not considered business days for water ordering purposes. One extra business day may be required by the Bureau of Reclamation if water is not readily available to the District such as drought conditions.
