The Project
 Ecology's Office of Columbia River is working
with the U.S. Bureau of Reclamation (Reclamation) to release additional
water from Lake Roosevelt behind Grand Coulee Dam. The releases will lower the lake by an additional foot in normal water years and 1.8 feet during drought years. The water will
be used to benefit municipal/industrial supply, the Odessa Subarea interruptible water right holders and instream flows.
In non-drought years, 30,000 acre-feet of water will be released to the
Odessa Subarea,
another 25,000 acre-feet will supply municipal and industrial (M&I) needs, and 27,500 acre-feet
will be used to enhance streamflows (82,500 total). An additional 50,000 acre-feet will be released during drought years with 33,000 acre-feet of that release providing relief for interruptible water right holders and 17,000 acre-feet supplementing instream flows.
Benefits
Economic Benefits
Once the M&I water is fully allocated for residential and commercial
use, it is projected to add 35,000 jobs and $3 billion in increased
value to the economy.
The water this project will provide for Odessa Subarea is expected to
protect over 780 jobs and $53 million in annual income. These benefits
are derived from the water brought to the Odessa Subarea from this
project, only. Please
see the
Odessa Subarea page for a full accounting of benefits.
The drought year releases are projected to save 140 jobs and $9.5
million in annual income.

Benefits
The project benefits fish by adding 27,500 ac-ft to streamflows.
In drought years, it will add an additional 17,000 sc-ft.
