2016 Water Assessment

    The allotment has been set at 3 acre feet per irrigated acre for the 2016 water season. The Board of Directors and Joint Committee will continue to monitor the water situation and adjust the allotment throughout the season as necessary. 

    The Owyhee Irrigation district board of directors have set the incurred O&M charges for the 2016 season as $58.00 per irrigable acre. This will be a $1.50 increase from last year. Those owners who have less than 5 acres will be assessed a charge of $75.00 for account fees plus the $58.00 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.

2016 Gopher Bounty Program

    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.

Malheur County ALERTS
Sign up to receive emergency alerts and severe weather warnings that could directly impact you and your family.

    This free service, powered by AlertSense,  allows fire, police and other emergency response agencies to issue emergency alerts to warn citizens of events such as severe weather, fire, flooding, hazardous materials, need for immediate evacuation, civil danger, local area emergencies, and missing persons.

    You can indicate the types of alerts and notifications you would like to receive and your preferred contact methods.  Enter your address or zipcode to receive advanced warning of severe weather or emergencies that directly impact the area in which you live or work. 

RRA Forms

    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. 

Aquatic Chemicals 

   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 ditchrider 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 years 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.

UPDATE 08/24/2016

Last night the Joint Committee met and decided that the 2016 irrigation season will end on September 30th. This includes both stored and pumped water. Please contact the office if you have any questions.

This is a courtesy announcement. All properties with stored water (from the dam) will not be allowed excess water this year. Due to receiving the full allotment of 4 acre feet, no transfers between properties will be considered. Please be aware if you have not logged into your CIP (Customer Information Portal) account recently. We would encourage you to check that regularly in order to utilize this tool to its full potential. We recommend giving all people in your organization the login information so they have access to this resource. They may also create an account of their own and obtain the same data. If you have not signed up for the Customer Information Portal you may do so at any time by following the link on our homepage at owyheeirrigation.org. This program is a great way to keep track of your water usage. Since the end of the irrigation season is now in sight our Ditch Riders are updating the information in the system more frequently. The days are now Monday, Wednesday, and Friday. If you have any questions please don't hesitate to contact us.

The Malheur County Court will officially lift the county burn ban on September 18th. The fire districts will also lift the ban on the 18th. Ontario City and Rural will require burn permits prior to any burning, barrel or open.

Water Outlook Report 2016

    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 run off predicted before the water season begins, over all 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 1:00pm 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
