Albeni Falls Dam

Albeni Falls DamAlbeni Falls Dam was authorized for construction under the Flood Control Act of 1950. This Act was signed by the United States Congress in response to a great flood that swept over the river valleys of the Columbia basin in 1948. Albeni Falls Dam was built from January 1951 to December of 1955 at a total cost of $34 million.

The dam is made up of two different parts: the powerhouse and the spillway. The powerhouse contains powerful turbines and generators that convert gravity-driven river water into hydroelectricity. The spillway can either store water for downstream power production and irrigation at other dams along the Pend Oreille and Columbia Rivers, or release water for upstream flood control. There is 136,000 cubic yards (61 million pounds) of concrete in the structure.

Today, it produces over 200 million kilowatt hours of electrical energy each year. When running at top capacity, the three Kaplan generators can generate 42.6 megawatts. That's enough power to supply about 15,000 homes. Bonneville Power Administration markets this electricity to customers primarily in the Pacific Northwest. This power production saves the United States from buying about 4.9 million barrels of imported oil each year.

Flow Update

For Immediate Release
Nov. 19, 2015

Lake Pend Oreille elevation at Hope Gauge: 2,051.3 feet
Albeni Falls Dam inflow: ~15,000 cubic feet per second
Albeni Falls Dam outflow: 16,000 cfs

Outflow from Albeni Falls Dam decreased from 18,000 to 16,000 cfs at 12 p.m. PST today.  Water managers are currently holding the elevation of Lake Pend Oreille between 2,051.0 and 2,051.5 feet, as measured at Hope.

Short term modeling forecasts are provided by the Northwest River Forecast Center.  Their projections for Albeni Falls Dam inflow, outflow and the Lake Pend Oreille at the Hope gage can be found here:
