USBR has issued a forecast of 96% water supply for Roza and the other proratable irrigation districts;

The official forecast also includes a low end forecast of 79% water supply which is predicated on receiving 50% of normal precipitation through the water season

Conditions are favorable for snowpack to build through March and April. Recent rains soaked into the snowpack without washing it away, which built up the snow-water equivalent. Snow density is 34% to 38% currently, which is comparatively good for this time of year.

The next forecast will be issued on April 6th.

April Agenda available....Board of Directors will meet for the regular scheduled Board meeting, Tuesday- April 11, 2017 at 9:00A.M., in the Executive Board room, in the basement office at Roza Irrigation District- Sunnyside.

The Roza Board approved award of a contract to Rotschy, Inc. for construction of the last phase of the Waste Way 5 Re-Regulation reservoir today. The contract is for $14.7 million. There were 8 bidders. The 1,600 acre foot project will be complete by summer of 2017 and is located in Washout canyon about 10 miles north of Sunnyside. It is the largest contract in the District’s history other than the contract with USBR to build the canal system.



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.  6:00 a.m. is the cutoff time because Roza's Watermaster submits orders to the Bureau of Reclamation at 6:00 a.m.


For example: Water orders received by the District before 6:00 a.m. on a Tuesday will be delivered Wednesday.  Orders received after 6:00 a.m. Tuesday (but before 6:00 a.m. Wednesday) will be delivered Thursday.

Similarly, orders received before 6:00 a.m. Friday will be delivered Monday and orders received after 6:00 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.
