Ochoco Irrigation District

Season & Flow Rates

The normal irrigation season starts April 15 and runs through October 15 of each year. The Board reserves the right to lengthen or shorten the season if the weather or water supplies justify a change.

At the beginning of the irrigation season, the OID Board of Directors will determine the water delivery rate in acre feet for that year. This decision is based on climate conditions and effects on stream flows and water storage.

During a normal year, the delivery rate is 3.00 acre-feet per acre of irrigated land.

Depending on climate conditions and water availability, the delivery rate can be set at a maximum 4.00 acre-feet per acre. It can also be set below 3.00 acre-feet per acre.

OID will attempt to deliver the amount of water requested by a water user, subject to limitations on water availability and other potential constraints.
