    The allotment has not yet been set for the 2017 water season. The Board of Directors and Joint Committee will continue to monitor the water situation and announce the allotment when we get closer to the beginning of irrigation. 

    The Owyhee Irrigation District board of directors have set the incurred O&M charges for the 2017 season at $62.00 per irrigable acre. This will be a $4.00 increase from last year: $2.50 increase on the normal Operation and Maintenance fee and another $1.50 for the Malheur Siphon project. Those owners who have less than 5 acres will be assessed a charge of $75.00 for account fees plus the $62.00 per irrigable acre. 


    In order NOT to incur interest charges, the water bill must be paid on or before April 15. Payments received in the mail with an April 15th postage date WILL BE CONSIDERED DELINQUENT IF RECEIVED AFTER APRIL 15TH.


    There will be a Gopher Bounty Program this year. The District will pay $1.00 per tail. Gophers must be caught within the jurisdiction of the Owyhee Irrigation District. LANDOWNERS are the ONLY authorized participants. Designated days for turning in gopher tails are Tuesday, Wednesday, and Thursday between the times of 8:00 A.M. and 8:30 A.M. Rotting tails will NOT be accepted. The tails will be counted and verified. A check will be issued to you the following month.

    This year we have finally turned the corner and are heading into a much better water season. A number of weather forecasters, with their long range reports, predicted a much warmer and dryer winter for our region. In some ways they were right, and in others they were wrong. With that said, November gave us good fall precipitation. Against all odds and forecasts, in December the El Niño condition of the west coast that was supposed to split and go around us lined right up and came straight at us. With those many days of storms came much-needed snow to the Owyhee Watershed. At the end of December, the basin was at 196% of normal. The month of January brought just above average for the month, but it did help hold the snow pack together into the first of February. The later part of February has brought warmer temperatures, and the lower to medium snow elevations have started melting and coming out as stream flow. It is encouraging to see the Romo gauge reaching almost 5,000 CFS, and reservoir levels have reached 183,440-acre feet. The maximum storage in 2015 was 205,389-acre feet. Only 21,949 AF is needed to reach last year’s peak. With much more runoff predicted before the water season begins, overall the outlook is a much better water season than we have seen in a number of years.

    Our Annual Water Users Meeting will be held on March 22, 2016, at 1:00 pm at the Four Rivers Cultural Center. The anticipated topics to be discussed are:

Snively Siphon Stabilization Project
Malheur Siphon Project (MWH)
Updated Water Forecast
Twilight Gravity Pipeline Project

    Just a reminder that if you own and/or lease 240 irrigable acres or more in the 17 Western states, you are required to complete a Federal RRA form. Water CANNOT be delivered until these forms are completed. 

If you are a new owner or a renter leasing 240 acres and you need more information, please call the District Office. 


   If you have been in the District Chemical Lock and Close Program in the past, the District will be sending instructions and information that water users will need in order to make an informed decision on the best way to manage your operation. 

    If you wish to participate must complete a Lock & Close Program Request Form. This must be returned to the District Office by April 14, 2017, if you do not want these chemicals to enter your head gate. For more information, please contact the district office, your ditch rider or the environmental coordinator.

     This year we will be using the AlertSense notification system for aquatic herbicide applications made to the canals and laterals. This alert system will contact the user by email, landline, text, and cell phone. Those who were on last year's list have been entered into the system for this year. Our hope is that this will keep our patrons better informed and provide documentation for our records.
