Topic: Hydroelectric dams on the Columbia River

  Columbia River article
Dams on the Columbia have contributed significantly to steep declines in historically strong anadromous fish runs.
The Columbia River first appeared on European maps in the early 17th century as "River of the West," when a Spanish maritime explorer Martin de Auguilar located a major river near the 42nd parallel.
Cartographers often labeled the "River of the West" as an estuary to the mythical Straits of Anian, or the Northwest Passage and located it anywhere from the 42nd to the 50th parallel.

 NatureScapes.Net NatureScapes.Net View topic - Hydroelectric dams in the Columbia River
Hydroelectricity is clean and renewable, but that claim rather rapidly starts to lose value if the effects of dams on the watershed, its ecosystem and its human inhabitants are taken into consideration.
Generating hydroelectricity is only one function of dams and quite a few have been built, also in the Columbia and its tributaries, that generate no power at all, or less than they potentially could.
Dams allow control of the water level upstream and of how much water flows further down, which for example can help prevent flooding1 and the water that is 'stored' in lakes behind the dams can provide water even during quite prolonged droughts.

The Columbia River is the largest river in volume flowing into the Pacific Ocean from North America.
These dams, like so many others in the world, came with a price: at one time the river was thick with salmon, and the presence of the dams together with overfishing have been major factors in the reduction of populations of this fish.
Other benefits the dams provide, besides hydroelectric power, include navigation and flood control, two areas that the first settlers to the Northwest were forced to grapple with many times.

 Keenleyside Dam - Wikipedia, the free encyclopedia
Hugh Keenleyside Dam is a hydroelectric dam spanning the Columbia River, 12 km (6.5 miles) upstream of the city of Castlegar, British Columbia, Canada.
The reservoirs behind the dam is named Arrow Lakes extending 232 km (145 miles) north to Revelstoke.
The dam was originally built in 1968 only to control the flow of water in the Columbia River for downstream dams, but in 2002 a 185 megawatt (MW) powerhouse was added.

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.
For the Columbia River Basin, the need for reservoir space to help reduce the risk of flooding is most important during two seasons of the year: in winter, when there are rain-induced floods, and in the spring and early summer, when there are floods from snowmelt and rain.

Dams clearly have had a significant impact, particularly those that eliminated access to fresh water habitat (preventing adult fish from returning to spawn), and those through which fish passage is provided but at reduced levels from natural conditions.
The juvenile fish bypass systems in place at seven of the eight lower Columbia and Snake River dams (another is planned for The Dalles) guide fish away from turbines by means of submerged screens positioned in front of the turbines.
During the juvenile fish migration seasons, from late March until fall, flows in the river are augmented, and water is spilled at the dams, to aid juvenile migration.

 The Environmental Literacy Council - Hydroelectric Power
Dams are built for controlling floods, generating power, providing drinking water, improving navigation, and for recreational, industrial, and agricultural use.
At the beginning of this century, hydroelectric power from dams supplied approximately 30 percent of the generating capacity in the U.S. Although hydroelectric power is a relatively clean source of energy and a renewable source, it is currently used to supply only about ten percent of our energy supply, according to the Department of Energy.
Within hours the leak became a flood, the dam was breached, and a wall of water flooded the farmland and towns downstream.

Failure of the Teton Dam on a tributary of the Snake River near Idaho Falls (in 1976) killed 14 people, obliterated one town (Wilford), severely damaged several others, and caused $3 billion (2002 dollars) in property damage.
The energy released when this dam ruptured was the equivalent of ten (20-kiloton) atom bombs, and it caused the greatest flood in North America since the last ice age.

 The Science of Salmon Recovery in the Columbia River Basin - The Impact of Hydroelectric Dams on Salmon Populations
The truth is that during the 40 year period of their intense preoccupation with building dams, from approximately the mid 1930s to the mid 1970s, the Corps of Engineers gave only grudging and token consideration to the impacts their dams would have on anadromous fish runs.
Stronger opposition to the dams from fishery scientists with more realistic assessments of their own capacities to mitigate the destructive effects of the dams on fish runs might possibly have prevented the building of some of them.
With the passage of the Mitchell Act in 1938, which allocated funds to mitigate against salmon declines in the Columbia River basin, fishery scientists were given the funds to construct additional hatcheries and to develop the hatchery technology they insisted was needed (Cone 1995).

If the hydropower dams were to be breached, much less electricity would be produced, which may raise the price of power and make it more expensive for wide segments of the economy in the West.
Dams, diversions for irrigation, logging, mining, and urban development all have made the river trips to and from the ocean increasingly difficult.
Before eight major dams were built on the Columbia River and the Snake River (the Columbia's main tributary), some 16 million salmon a year filled annual fish runs.

The impact of the Columbia River on the life and economy of the state can scarcely be overestimated.
The dams on the Columbia's lower course were designed as power, flood-control, and navigation projects, whereas the dams on the upper course are integral to the Columbia basin project (with the Grand Coulee as the key unit), providing not only power and flood control but extensive irrigation to the Columbia Plateau.
Meanwhile the British, although despairing of control over the area S of the Columbia, were still determined to retain the region to the north; the Americans, on the other hand, demanded the ouster of the British from the whole of the Columbia River country up to a lat.

If dam removal is done as a part of a comprehensive strategy toward restoring and recapturing the economic value of salmon harvests for the region, then at some point it becomes more economical to remove these dams than to maintain them.
Because the region's hydropower system is on the Columbia and Snake rivers, this first and last life cycle is called "hydro." Some believe that because dams symbolize the barrier between the ocean and the salmon's return, we should simply remove or breach the four lower Snake River dams.
The social costs of removing the dams are not only borne by navigation interests, but those of irrigated agriculture, local communities, travelers who recreate on the reservoirs and anyone who uses electricity to light or heat their homes.
