Former Roza Manager Ron Van Gundy passed away yesterday afternoon surrounded by his family and friends. Van Gundy was hired in 1968 and was appointed Assistant District Manager in 1971 and District Manager in 1982 until retirement in 2002. He continued to work part time since then as Policy Director. He was Rozaís longest term employee in the history of the district with his 49 years of service, and also the longest serving District Manager. He managed Roza with a steady hand through major droughts in 1973, 1977, 1992-94, 2001, and 2005 and earned the respect of water managers across the west as well as Roza growers.  He spearheaded Rozaís award winning water conservation program which has resulted in the piping of over 300 miles of canals. He partnered on an innovative water quality program with the Sunnyside Valley Irrigation District which has resulted in dramatic water quality improvements in the lower Yakima River over the past 20+ years. He hired the first fisheries biologist in the area to work for an irrigation district and supported fish passage and screening improvements at irrigation facilities. He also fostered working relationships with several environmental and conservation groups. He was deeply involved in protecting Rozaís water rights for nearly 40 years. The $31 million Wasteway 5 re-regulation reservoir in Washout Canyon north of Sunnyside was a project he led for over thirty years. It is complete and will come on line in a few weeks (see photo-Jim Willard photo credit). He was proud of the strong relationship that he helped to establish between Roza and the Yakama Nation on water and fisheries issues. He was asked to apply for Commissioner of the U.S. Bureau of Reclamation in the 1980s.  Ron was the 2001 recipient of the Washington State Water Resources Associationís Water Resources Leadership Award for excellence in water resources management, and the WSWRA distinguished service award in 2016. He served as president of the association in 1986-87. He was honored by the Northwest Irrigation Operators with the Headgate Award in 1996 Governor Inslee expressed his condolences to the Van Gundy family in a letter and praised Ronís leadership and vision.  He is survived by his wife and three grown children and numerous grandchildren. Smith funeral home in Sunnyside is handling the memorial arrangements. Check the Roza website for updates.

Board of Directors will meet for the next regular scheduled Board meeting, Tuesday- November 7, 2017 at 9:00A.M., in the Executive Board room, in the basement office at Roza Irrigation District office- Sunnyside.


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.
