SPOKANE VALLEY, Wash. – (June 20, 2024) – The U.S. Department of Agriculture Natural
Resources Conservation Service – Washington (NRCS-WA) has adopted the 2012 Odessa
Subarea Special Study Final Environmental Impact Statement (FEIS) produced by the Bureau of
Reclamation (Reclamation) in cooperation with the Washington State Department of Ecology
(Ecology).
NRCS-WA issued a Record of Decision (ROD) that selects Alternative 4A, the same alternative
that was selected in the Reclamation 2013 ROD for the FEIS. East Columbia Basin Irrigation
District (ECBID) in partnership with Reclamation, Ecology, and NRCS-WA will base the
development of a Watershed Plan under the Watershed Protection and Flood Prevention Program
authorized by Public Law 83-566 (P.L. 83-566) on the existing FEIS. With an Authorized
Watershed Plan, ECBID will be eligible to pursue NRCS P.L. 83-566 funding to support the
phased implementation of the distribution systems needed to supply surface water to eligible
lands currently irrigated with groundwater under the Odessa Groundwater Replacement
Program.
Located in Central Washington, ECBID is the largest irrigation district in the state, with
authorization to irrigate 472,000 acres. Currently, 169,000 acres are developed and managed by
4,500 landowners within the federal Columbia Basin Project (CBP). The FEIS analyzed the
potential to replace groundwater irrigation on up to 102,600 acres of land in the Odessa Subarea
with surface water from the CBP. The alternatives put forward in the FEIS analyzed the potential
to replace groundwater irrigation on a range of acreages (up to 102,600 acres) with varying
diversion amounts of CBP surface water (up to 273,000 acre-feet).
The Odessa Subarea aquifer is experiencing significant declines in groundwater levels.
Domestic, commercial, municipal, and industrial uses, as well as water quality, are also affected.
Many of the groundwater wells in the area are currently drilled to a depth of 800 to 1,000 feet,
with some as deep as 2,100 feet. Some wells in the area have been reported out of production.
Drilling deeper wells is not feasible because deeper water may not be available, may be
potentially unusable, or may be too expensive to access. As a result of this decline, the ability of
producers to irrigate their crops is at risk.
The Reclamation 2013 ROD and the NRCS-WA 2024 ROD identify Alternative 4A: Partial
Modified-Replacement-Banks with Limited Spring Diversion Scenario as the selected
alternative. Alternative 4A seeks to replace acre-for-acre groundwater irrigation on 70,000 acres
in the Odessa Subarea with 164,000 acre-feet of new Columbia River diversions. Since
Reclamation published the FEIS in 2012, the Odessa Groundwater Replacement Program, a
consortium of local, state, and federal partners, has worked towards phased implementation of
Alternative 4A.
The adoption of the FEIS and development of a Watershed Plan under P.L. 83-566 are sponsored
by ECBID with funding and technical support from NRCS-WA, Reclamation, and Ecology.
Columbia Basin Conservation District, Farmers Conservation Alliance, and Parametrix are
assisting with the planning process.
