A three-mile segment of the Walla Walla River near Milton-Freewater, Oregon, was dewatered each summer for the last century creating the need for fish rescues.  The rescues have not been necessary the last sixteen years after aggressive irrigation efficiency programs and new wells now maintain at least 27 cfs instream throughout the spring and 25 cfs instream throughout the summer.  However, half of these bypass flows are created by an increase in supplemental well use at unsustainable rates.  Additional irrigation conservation practices, combined with winter/spring groundwater recharge, will allow irrigators to reduce their demand on the river, reduce negative impacts to groundwater, and protect the conserved water as instream water rights. Projects planned under this contract will help WWBWC and the Walla Walla Basin continue their efforts to increase water in the Walla Walla River, its tributaries, and the highly connected shallow aquifer in order to ensure viable fish habitat in the basin.
