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
Oct. 23, 2014

Lake Pend Oreille elevation at Hope: 2054.0 feet
Albeni Falls Dam inflow: ~17 kcfs
Albeni Falls Dam outflow: 27.5 kcfs

The current outflow from Albeni Falls Dam is 27.5 kcfs, 8 kcfs of which is being released over the spillways as repairs are made to the third generating unit.  The generating unit is expected to come back online this evening, 23 October.  When this occurs, estimated for 1900 PDT, the spillways will be closed and total outflow from the dam will increase to the new powerhouse capacity, approximately 29 kcfs.  The plan into the weekend and next week is to continue to release powerhouse capacity, which will gradually decrease as the lake level drops.  Expect the lake level to drop 3 to 6 inches per day in October.  Outflow will be decreased.

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:
