Dams

American Society Of Civil Engeineers

The American Society of Civil Engineers is out with its report card on infrastructure in Idaho. While the Gem State did better than the nation’s grade of “D+,” the society’s findings paint a less-than rosy picture.

Idaho is neither leading the class nor passing notes in the back with a grade of C-. The American Society of Civil Engineers describes the “C” category as infrastructure that’s mediocre and in need of attention.

Idaho officials have approved an agreement allowing a utility company's $216.5 million in relicensing expenses for a three-dam hydroelectric project on the Snake River on the Idaho-Oregon border.

The Black Canyon Dam was built in 1924 on the Payette River northeast of Emmett. The two original generators create 10 megawatts of power and help protect against flooding. The Bureau of Reclamation was planning to install a third power plant at Black Canyon, but the project is now on hold.

A debate about four Washington state dams has put the spotlight back on a longstanding story about salmon. The Idaho Statesman has begun a series about the endangered species, which asks whether destroying the dams will be enough to save the fish. Frankie Barnhill sat down with Statesman reporter Rocky Barker to learn more about what’s at stake.

The recent threat of catastrophic flooding at the Oroville Dam in Northern California has abated for the moment, but the incident dredged up old memories of Idaho's own dam catastrophe.

In June of 1976, the earthen Teton Dam in eastern Idaho failed, killing 11 people and causing $2 billion in damage. It cost $100 million to construct, but the government ended up paying over thrice that in damage claims linked to the failure.

Environmental groups are asking a federal court to halt 11 infrastructure projects on four lower Snake River dams in Washington state that could ultimately be removed if a pending review determines the dams need to come out in order to help salmon.

The 45-page notice filed late Monday in Portland, Oregon, estimates the cost of the projects at $110 million.

Federal authorities have rejected a request by an irrigation company in southeastern Idaho to build a dam on the Bear River.

The Federal Energy Regulatory Commission on Thursday voted to deny Twin Lakes Canal Company's license application for a 109-foot-high dam with a 10-megawatt powerhouse.

Commissioners say the project would inundate the Bureau of Land Management's Oneida Narrows Research Natural Area with resulting loss of recreation, wildlife and fishing resources that could not be replaced.

On September 17, the flow in the Boise River dropped from 621 cubic feet per second (cfs) to 335 cfs. The drop occurred at Barber Dam, a hydroelectric plant east of town.

The dam is operated by Enel Green Power, an international hydropower company. The company leases the plant from Ada County. According to Enel operations director Conrad St. Pierre, an electrical failure on the Idaho Power circuit occurred the morning of September 17.

Dozens of people in boats, kayaks, and canoes will join a flotilla Saturday on the Snake River to protest four dams that advocates say are killing fish and costing taxpayers money.

Greg Stahl is with Idaho Rivers United, one of the groups putting on the flotilla. He says most people don’t know much about the four dams on the river between Lewiston, Idaho and Pasco, Washington, in part because of their remote location.

A new study from an environmental think tank ranks Idaho among the states with a low ecological footprint. The study from the Global Footprint Network ranked states against one other on a number of green measures. Idaho received the top ranking for electricity generated from renewable energy. Washington and Oregon come in second and third, respectively.

A close look shows the renewable source that earned Idaho its high ranking is hydropower, with wind and biomass taking up smaller shares.

After it became clear that a power outage and failed alarm system at the Barber Dam caused the Boise River to flow nearly dry for eight hours on February 4, Marie Callaway Kellner of the Idaho Conservation League began asking for action.

About 100 people showed up at a meeting Wednesday night to hear what caused an east Boise dam to malfunction in February, and what steps are being taken to make sure it doesn’t happen again.

Part of the Boise River was reduced to nearly a trickle for about eight hours overnight on February 4 when a power grid fluctuation caused the Barber Dam to shut down. Ada County owns the dam, but leases the hydroelectric plant to Enel Green Power.

The public will have the chance to talk with elected officials about a power outage that caused the Boise River to dry up earlier this year. The Ada County Commission is holding a meeting on May 27 to discuss the accidental dewatering.

After a power plant's alert system failed causing Wednesday's dramatic drop in the Boise River flow, Idaho Fish and Game biologists are concerned about potential impacts to wildlife. The river went from flowing at 290 cubic feet per second (cfs) to 81 cfs in a matter of hours.

Barber Dam's power was restored early Wednesday morning, constricting the flow of water for nearly eight hours.
