Finally, nitrogen load at the Columbia River mouth is about 2-20 times larger than that at the Canadian border. [4] This gradient in nitrogen distribution is partly a result of the inputs of the Columbia's major tributaries, the Snake River and the Willamette River. The Snake and Willamette rivers together contribute about 50-80 percent of the ...
Elevation varies from 300 to 1,200 feet (90 to 370 m). Today, the region is the driest and warmest part of the Columbia Plateau, with mean annual precipitation varying from 7 to 10 inches (180 to 250 mm). Major irrigation projects provide Columbia River water to the region, allowing the conversion of large areas into agriculture.

Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation.Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science.
The irrigation water provided by this project greatly benefits the agricultural production of the area. North Central Washington is one of the largest and most productive tree fruit producing areas on the planet. Without Coulee Dam and the greater Columbia Basin Project, much of North Central Washington State would be too arid for cultivation.
Plans show a proposed footprint of almost 22,000 square feet.
