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.
Looking at average river flows at the Dalles Dam over the course of the year is one way to see the difference between unrestricted water flow and the use of reservoirs to make this flow more constant.

  Columbia River Basin
Early non-Native use of the river paralleled that of the Indians'—fishing for salmon, using the river as a transportation conduit, locating settlements on the flat, fertile floodplains.
While many of the Columbia's tributaries were dammed and ditched in the late nineteenth and early twentieth centuries, it was not until the 1930s that the mainstem of the Columbia was developed.
Hundreds of dams impound the river and its tributaries, more than half a dozen fish species are at risk of extinction, and pollutants ranging from human sewage to radioactive wastes flow through the river and into the ocean.
