Columbia-Pacific Northwest Region

Oxbow Incentivized Managed Aquifer Recharge Project

Proposed Action

Residents and visitors using the paved recreation pathway can expect to be detoured through adjacent grassy areas around any active construction activities. These detours will be for short distances as construction moves along the route of the pipeline. The entire pipeline should be replaced in two weeks or less. Effects to recreation should be minimal, short term and limited to the construction period.

Construction would result in short-term increases in noise and dust in the local area. Some of the manicured landscape along the paved pathway also would be temporarily disturbed. Residents, visitors and wildlife could see minimal and short-term effects from construction activities.

Irrigation deliveries will not be impacted by construction, and the source canal will be capable of transporting the additional 20 cfs to the ponds without impacting existing irrigation deliveries. Recharging Snake River water as well as treated wastewater would improve drought resiliency by increasing aquifer storage and subsequent spring outflows along the Snake River. Water quality in the Snake River also would benefit from less treated wastewater being discharged into the river.

The final EA and FONSI were completed on September 21, 2019, in accordance with the National Environmental Policy Act.
