Dams at Risk: 65-Foot Crack in Washington State Dam

A large crack has been found in the Wanapum Dam on the Columbia River which supports the utility power supply to a major cluster of data centers in central Washington state.

 

65-Foot Crack Found in Washington State Dam (Feb 25)

The 2-inch-wide crack was found Thursday after divers were sent into the Columbia River because engineers detected a misalignment in a spillway on Wanapum Dam near the central Washington town of Vantage, said Tom Stredwick, a spokesman for the Grant County Public Utility District.

The Wanapum Dam generates more than 1,000 megawatts of electricity for the Grant County PUD, the utility that provides electricity to major data centers operated by Microsoft, Yahoo, Dell, Sabey Data Centers and Vantage Data Centers.

On February 25, dam officials noticed an irregular bowing of the dam near a section of a spillgate pier along the mile-long structure. Divers examined the area Thursday and discovered a two-inch wide crack running horizontally, located about 75 feet below the water’s surface. It runs the entire width of the 65-foot-wide pier.

The risk of a failure of the dam is high enough that the county has initiated an emergency plan. To relieve pressure on the dam, the water level is being lowered by 20 feet.

Owen Falls Dam in Uganda Falling Apart (Feb 28)
The Owen Falls dam in Jinja could cave in, if the cracks and damage to the dam are not repaired, an official of Eskom, the hydro power generation company, has said.

Huge cracks continue to develop in the walls and supporting pillars of the dam. Water continuously sips through the gaping holes, expanding the cracks and making the dam weaker by the day.

Lake Manatee Dam at Risk of Collapse (Feb 14)

The Lake Manatee Dam in Bradeton, Florida is in a "severely distressed state" because of erosion, engineering consultants have found, forcing county officials to take corrective actions.

Heavy rains over four or five days could compromise the Lake Manatee Dam, Manatee County government warned in a news release February 14.

As a precaution, workers have begun to lower the water level of the lake.

Engineers and officials are concerned that the dam's clay core may have been compromised.

Water Gushes over Crumbling Dam in Zimbabwe (Feb 9)

A dam on the Tokwe river in the Masvingo area of Zimbabwe is close to bursting as water from heavy rains finding its way through gaps in the uncompleted dam wall.

Construction of the Tokwe Mukorsi dam began in 1998 but stalled in 2008. The dam was due to be completed at the end of last year but the deadline has passed with construction still not finished. Pictures from the area show water gushing through breaks in the wall and a huge build up of water in the reservoir behind it. Villagers have been evacuated as quickly as possible, with around 4,000 people believed to be at risk should the dam burst.

According to the Daily News, the Zimbabwe Air Force is helping people evacuate. The Minister for Masvingo province is quoted as saying that the government is on high alert and "A helicopter from the AFZ has been airlifting some families who were marooned by the floods but we are not yet sure how many people are still marooned."

"All dams will break either during the pole shift or in the months leading up to the hour of the shift. Look at the structure of the dam! It assumes that rock holding both sides of the dam will remain in place and not move. Of course these sides will move. This is a subduction zone! There is mountain building and even where the mountains are not being pushed upward, they are moving from side to side. Some parts are more fluid than others, which are more resistant during any earthquake thrust, so there IS inevitably movement to the side. They will pull apart, slide forward or backwards, but in any case the water will find its way around the dam."

Dam collapse in Almeria sweeps cars away

Thursday, 07 September 2017 13:03

A DAM partly collapsed in Almeria, catching car owners who parked in the drainage channel by surprise.

Footage shows some drivers getting their cars out of the way just in time, while another battles against the current to retrieve his vehicle. Some cars can also be seen being swept away.

Residents hedged their bets after the weather had returned to normal in Pulpi, despite being warned not to leave their cars parked in a drainage channel.

At the time of writing It was unclear what caused part of the dam wall, holding a private irrigation reservoir, to collapse.

Toxic tsunami kills everything on its path in the desert of Israel

Toxic wastewater that surged through a dry riverbed in southern Israel during the weekend left a wake of ecological destruction more than 20 km (12 miles) long.

The tsunami of acid most probably killed all the plants and animals in the valley and will trigger, on the long term, large functional ecological problems.

The flood began last Friday when the 60 meter (yard) high wall of a reservoir at a phosphate factory partially collapsed, letting loose 100,000 cubic meters (26.4 million gallons) of highly acidic wastewater in the Ashalim riverbed – enough fluid to fill 40 Olympic-sized pools.

The toxic torrent snaked through the desert, singeing anything in its path, before collecting again hours later in a pool several kilometers from the Dead Sea, already eaten by sinkholes.

Days later, the ground is still stained a dark brown and giving off a nauseating acidic stench, more potent than a highly chlorinated swimming pool.

Israel’s Ministry of Environment has opened a criminal investigation into the plant’s owner, Rotem Amfert, and its parent company Israel Chemicals (ICL).

All the plants and animals in the valley during the tsunami of acid were probably highly damaged, probably dead,” said Oded Netzer, an ecologist for the ministry. “In the long term, there will be soil damage and large functional ecological problems.

He said weeks of intense clean-up work, including pumping out small pools of the wastewater that remain along the path, lay ahead, and complete rehabilitation would likely take years.

Levee in northeast Arkansas fails, weather service says; flash flood emergency declared

This article was published today at 9:06 a.m.

Water rises from the Black River Wednesday morning flooding part of Pocahontas.

A levee on the water-logged Black River that experienced record levels of rain in northeastern Arkansas gave way Wednesday morning, causing a flash flood emergency for people in the area, weather officials said.

The levee near the town of Pocahontas in Randolph County was breached, the National Weather Service of Little Rock said shortly before 8:40 a.m.

That area was said by the agency to be in a flash flood emergency with life-threatening flooding likely.

At 7 p.m. Tuesday, the Black River level was 29.1 feet, the Arkansas Democrat-Gazette reported. Levees in that area of the river are reportedly built to withstand 28 feet.

Several water rescues had been performed by 9:45 a.m. just south of Pocahontas in Shannon near the intersection of U.S. 67 and Arkansas 90, the National Weather Service of Memphis said in a tweet.

There were multiple breaches along the earthen levee structure, said Scott McNeil, a forecaster with the Memphis weather service office said. Details on how the levee failed were not immediately known, said McNeil, who noted the Army Corp of Engineers as well as local emergency management officials are tracking the flooding at the scene.

Typically when earthen levees fail, it means water got too heavy and washed out part or parts of the structure, said Dennis Cavanaugh with the National Weather Service in Little Rock.

The breach “hasn’t happened before" he said.

"So we don’t know what’s going to happen," he said. "The main concern is that the east side of Pocahontas, it’s already flooding, but it will receive even more flooding.”

The levee failure will “put a lot of water where it’s not supposed to be,” Cavanaugh said.

At least seven deaths have been attributed to weekend storms that brought 6 to 8 inches of rain to northern Arkansas and high levels of precipitation to much of the state.

Officials earlier predicted the collapse of the levee would send a "wall of water" toward neighboring Lawrence County.

An evacuation order was issued Monday for the eastern portion of Pocahontas which includes about 150 homes, an assisted-living apartment complex and many businesses. Most people left by Tuesday but a few residents reportedly opted to stay in their homes rather than seeking shelter elsewhere.

The National Weather Service of Memphis on Wednesday morning noted on Twitter that the levee had failed and told Pocahontas residents and people in the area to "seek higher ground now."
