The river also provides drinking water to numerous communities along its course, and irrigates 600,000 acres of farmland. Between the U.S. and Canada, the river’s 19 hydroelectric dams provide about half the region’s supply of electricity, in addition to providing flood control benefits.

Why is the Columbia River important to American history?

For its first approximately 150 miles (241 kilometers) in the United States, the Columbia forms the reservoir behind Grand Coulee Dam. The river then bends west, south and east through central Washington, turns south and then west, and forms the border between Oregon and Washington to the Pacific Ocean.

What was the strongest argument for building a dam on the Columbia River?

The report declared that the Columbia had the potential to be “the greatest system for water power to be found anywhere in the United States” and that the river could be controlled and managed as one system.

Why is the Columbia River important to the West Region?

In short, the Columbia River Basin is an essential reason for the Northwest being a dynamic and highly prosperous region within the nation and the world. Hydropower, flood control, irrigation, navigation and recreation are specific benefits that the uniqueness of the Basin and its river system provide.

What’s the purpose of dams?

A dam is a structure built across a stream or river to hold water back. Dams can be used to store water, control flooding, and generate electricity.

Is the Columbia River polluted?

The Columbia River Basin receives pollution from factories; wastewater treatment plants; and runoff from agricultural lands, logging, and industrial sites, and city streets. Studies on Columbia River resident fish, otters, bald eagles, and other species reveal the heavy toll of toxic pollution.

Why are dams important to the West?

About Dams and Fish on the West Coast Dams provide electricity, flood control, recreation and transportation as well as water for domestic and agricultural use. Dams affect the way water moves down a river, by changing the amount and timing of flow, as well as its temperature and chemical characteristics.

What is the purpose of most dams?

Dam Basics The purpose of a dam is to impound (store) water, wastewater or liquid borne materials for any of several reasons, such as flood control, human water supply, irrigation, livestock water supply, energy generation, containment of mine tailings, recreation, or pollution control.

Is the Columbia River safe to swim in?

Are dams good or bad?

Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.

Why is the Columbia River basin so important?

In short, the Columbia River Basin is an essential reason for the Northwest being a dynamic and highly prosperous region within the nation and the world. Hydropower, flood control, irrigation, navigation and recreation are specific benefits that the uniqueness of the Basin and its river system provide.

What does the Columbia River flow through?

Rivers west of the divide, such as the Columbia, flow through the region’s topography and toward the Pacific Ocean. As the water flows to the Pacific, the Columbia River is second only to the Missouri-Mississippi River System in terms of annual run-off.

How did the Columbia River affect Native American life?

Indigenous people relied on annual anadromous fish runs in the Columbia and other major rivers and smaller streams, making Native American communities on the lower river—where fish migrated in massive numbers—among the richest in material resources in North America.

Why was salmon important to the Columbia River Indians?

For centuries, dried and pounded salmon was a sustaining food and an important trade item for tribes on the Columbia. By the mid-twentieth century, Indian fishers used more than 450 fishing platforms at Celilo Falls to catch migrating fish, many of them weighing more than fifty pounds.
