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
April 20, 2015

Lake Pend Oreille elevation at Hope: 2,053.8 feet
Albeni Falls Dam inflow: ~31,000 cubic feet per second
Albeni Falls Dam outflow: 27,000 cfs

Outflow from Albeni Falls Dam increased this morning from 27,000 to 29,000 cfs over a one-hour period starting at 11 a.m. PDT today. 

Seattle District Water Management has taken over control of day-to-day regulation of Albeni Falls Dam during the refill period which will continue through late-June.  The current plan for the remainder of April is to target being below 2,055 feet at the Hope Gage for the end of April.  While elevation 2,056 feet is the upper limit the lake can be at on April 30th, the lake is being held lower in consideration of downstream Columbia River needs that will extend through mid-May.  Lake Pend Oreille, unless the Dam is on freeflow, will refill towards the summer operating range of 2,062 to 2,062.5 feet by mid to late June depending on hydrologic conditions and flood risk management needs.
