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 to make an informed decision on the best way to manage your operation.

If you wish to participate, you must complete a Lock & Close Program Request Form. This must be returned to the District Office by April 10, 2022, if you do not wish to have these chemicals to enter your headgate. For more information, please contact the district office, your ditch rider or the Owyhee Irrigation District's environmental coordinator.

This year we will again be using the AlertSense notification system for aquatic herbicide applications made to the canals and laterals. This alert system contacts 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. This system keeps our patrons better informed and provides documentation for our records.
