25,000 acres of arable land flooded in the Arrow Lakes region
14 communities and about 2000 people displaced
Several hundred more displaced by Lake Koocanusa
behind Libby dam
Were Arrow Lakes farming families adequately
compensated for their losses?
What is the value of agricultural land in an
increasingly food insecure and water scarce world?
Does food security require sustainable agricultural
communities?

Evaluation of the Effect of downstream benefits
to Washington State Agriculture Under the
Columbia Treaty on the Competitive Positioning
of B.C. Producers.
“The Facts”
• In 1962 the Columbia Basin Project was supplying irrigation
water to 452,756 acres of land.
• By 1972 the total had increased to 517,400 acres
• By 1992 the total had increased to 577,000 acres
• Today the total is 671,000 acres.
But Holm’s argument is NOT about an increase in
irrigated acreage due to Canadian storage
It is about LATE SUMMER irrigation capacity
“The Facts”
• Prior to construction of the CRT dams, the Banks Lake system
could not provide reliable late summer irrigation water to the
Columbia Basin Project area.
• Late summer flows in the Columbia can be as low as 1/5 of
the average flow for the year.
• According to Holm’s calculations, the Canadian contribution to
late summer storage is sufficient to provide an additional 2
acre-feet of irrigation water to 532,000 acres, thus providing
them with a SECURE late summer supply.
• Once CBT dams were constructed, Washington State farmers
began shifting to higher value crops: apples, alfalfa,
asparagus, potatoes, wheat, onions, grapes, rather than
multiple hay crops, barley, oats and sugar beets.
Agricultural Development of the Columbia
Basin Project Area, 1962-1992
• Area planted in apples increased from 484 to 27,433 acres.
• Apple yield per acre increased by 204%.
• Apple crop value increased from 1.3 to 150 million dollars.
• Area planted in grapes increased from 45 to 13,909 acres.
• Asparagus: from 628 to 35,941 acres.
• Onions: from 1,249 to 29,614 acres.
• The real market value of all crops harvested in the Columbia
Basin Project area increased by 219.2% compared to a 39%
increase in the rest of Washington State (calculated in
constant 1992 CA$).
The Cost of Water
• Bureau of Reclamation provides hidden subsidies.
• Farmers pay only 15 cents on every dollar spent on
irrigation infrastructure and system maintenance.
• They receive other subsidies for rural electrification and
pumping costs.
• US farmers receive an additional hidden subsidy by
receiving CRT storage water at no cost to them.
• Farmers pay Bureau of Reclamation an annual fee, not a
charge per volume used
The Quincy Mound
Deep aquifer (basalt):
29,000 acre-feet
Upper aquifer (overlying
unconsolidated deposits):
currently stores 3.5 million
acre-feet (Banks Lake
storage capacity is only
715,000 acre-feet)
The Pasco Mound
Deep Aquifer:
23,000 acre-feet
Upper Aquifer:
now stores 5 million
acre-feet

Second use of the same water
(private well in the Quincy Mound area)
Washington State Department of Ecology issues permits to
individual applicants for groundwater use.
Water users must sign a contract with the Bureau of
Reclamation, the owner of the water.
“An economic analysis was conducted for the 15 new permits
Ecology issued in spring 2010 for the Quincy Basin. It was
calculated that these permits will increase land values by
$83M, income from farm production by $24.22M, and add
over 1000 jobs to the local economy.

Volume of mound water licensed in the
Quincy Basin
• 177,000 acre-feet total annual withdrawal
• (out of a total of 3.5 million acre-feet)
• Total volume of water delivered to the Quincy Basin
from Banks Lake? about 1 million acre-feet
• Mound water thus currently allows for the re-use of
about 15% of the total volume of CBP irrigation water
Potential third use of the same water

Final use of the water
(private well in Pasco mound area)
By scaling the analysis done for the 15 Quincy permits to the
117 pending applications for the 508-14 area, a rough
approximation of the economic returns can be made:
• An $178.4M increase in agricultural land value
• An $468M increase in commercial land value
• An $189M annual increase from increased agricultural
production and cycling the money through the economy
• 2122 new jobs from development of agricultural systems
and cycling the money through the economy
• 6014 new jobs from commercial development and cycling
the money through the economy

How to Integrate Agriculture in a
Comprehensive Basin-wide Governance
• Broaden the scope of the Columbia River Treaty to
include ecosystem functions, fisheries, agriculture,
tourism, recreational hunting and fishing…
• Or, create a new comprehensive agreement in which
the treaty becomes one of several cross-border side
agreements.
• At a minimum, provide for an equitable distribution
of agricultural benefits in British Columbia and
Washington.
• Agriculture is too big a player to leave out…
