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."

Texas flooding: dam threatens to collapse after lake overflows near highway - TomoNews

Georgia lake VANISHES overnight after 50-year-old dam gives way in ferocious storms - just the latest wave of freak weather ruining U.S. summer

  • Aspen Lake in Coweta County, Georgia, drained overnight after a rainstorm
  • It's believed a dam keeping the water in place broke away allowing the lake to drain
  • Residents are devastated but do not expect any help to rebuild because the lake was constructed on privately-owned land

The residents of Newnan in Coweta County, Georgia, had lived around their beautiful neighborhood lake for decades.

Surrounded by lush woodland and complete with jetty's in which they could sail their pleasure boats, the entire community was devastated to find that overnight it had completely disappeared after a freak thunderstorm.

Their favorite water feature, known as Aspen Lake, was completely wiped off the map (or rather drained!) last weekend as a slow-moving storm passed through the area.

A nearby dam that kept the water in place simply broke apart following years of neglect. It allowed the water to flow out, leaving nothing more than an enormous puddle of mud in its place.

Drained: An oversized puddle of mud is all that's left of Aspen Lake in Coweta County, Georgia

What Exactly Is Going On At Lake Mead?

Following our exposure of the plunge in Lake Mead water levels post... officials were quick to point out that the drop was "due to erroneous meter readings" - which in itself is odd given we have not seen such an aberration before in the measurements. The data today shows a super surge in the Lake Mead water level - which, even more mysteriously, indicates from pre-earthquake to now, theLake has risen by the most in a 3-day-period in years (as long as we have found history). How was this level 'manufactured' you ask? Simple - discharge flows from the Hoover Dam were curtailed dramaticallyWe are sure there is a simple explanation for all this...

Yesterday we noted the plunge in Lake Mead water levels...


Officials said - do not worry, the readings are faulty...

Which resulted in this miracle...


The biggest 3-day net surge in water levels (0.7 feet from Thursday to Sunday) on recent record...


How was this miracle achieved (given the general lack of precipitation)? Were discharge levels curtailed drastically?


Nope - nothing odd here at all...

Officials in Pearl River County tell us they are working to drain an entire 50 acre lake in the Amackertown community after a leak was discovered in a dam on Wednesday.

County spokesman Tony Bounds said the dam, located just miles from the Pearl River/Marion County line, was in "imminent danger" of breaking.

To reduce that risk, county officials called in a private contractor to perform a controlled breach on the dam to relieve some pressure.

Bounds told WLOX News on Thursday that the initial four foot wide trench that was dug to relive the pressure has expanded to 30 feet wide. Emergency officials were left with no other choice than to drain the entire lake. Officials say the process should take two or three days to complete.

According to digital mapping performed by the National Weather Service and the Mississippi Department of Environmental Quality, the water from the lake will make its way down the drainage basin and into the Pearl River. MDEQ officials do not expect the drainage project to affect area water levels.

Bounds says no structures, houses or roads will be affected as crews work to drain the lake.

Emergency officials are asking people to stay clear of the area until the problem is resolved.

Dam collapse prompts evacuation in northern Vietnam

A section of Dam Ha Dong Reservoir’s main dam was also damaged on Thursday.

At least 115 households were evacuated after a dam collapsed early Thursday in the northern province of Quang Ninh; no casualties have been reported.

The secondary dam of the Dam Ha Dong irrigation dam broke at 5:30, flooding Dam Ha Town, the provincial paper quoted Hoang Giang, a Dam Ha District spokesman, as saying.

Giang said that incessant rains that began on Wednesday night overloaded the reservoir.

“Water began spilling over the dam wall at around 4 in the morning and collapsing one of the three secondary dams,” he said, adding that water level in the dam has increased to 60 meters deep at around 10:30 am on Thursday.

Dang Huy Hau, Quang Ninh’s vice mayor, arrived at the site on the same day and oversaw the evacuation of 115 households in Dam Ha Town and Quang Tan Commune.

Relevant forces, including military units, were mobilized to repair the collapsed dam and provide emergency assistance as the flood waters began receding around noon on Thursday.

The material damages have yet to be calculated.

Located on the Dam Ha River, the Dam Ha Dong serves as a reservoir for the irrigation of nearly 3,500 hectares (8,648 acres) of agriculture land.

It also provides water to a community of roughly 29,000 people.

The VND500-billion (US$23.5 million) dam, which broke ground in 2006 and finished in late 2011, also prevents floods to the river’s lowlands.

Dam Failure in Brazil Kills 3 (Sept 10)

At least three mine workers are dead after a tailings dam collapsed in Brazil.

According to a report by EM Digital (written in Portuguese), rescue personnel were called to the accident early on Wednesday in Itabirite, the central region of Minas Gerais

The military were called to the accident around 7:50 a.m. and worked for four hours to rescue buried miners. The Municipal Secretary of Environment, Antonio Marcos Generoso, confirmed that three are dead in the slide. Another was transported to João XXIII Hospital in Belo Horizonte.

Officials did maintenance at this dam early in the morning when the accident happened. A large amount of waste was released on top of vehicles and workers. A truck driver, a bulldozer with operator and a Fiat Uno with the driver were all buried. Firefighters worked by hand to try to find them.

Workers on the site are being accounted for and the dam is being monitored.

Mount Polley mine spill 78% larger than 1st estimates

Imperial Metals now estimates the spill included 25 million cubic metres of water and waste

CBC NewsPosted: Sep 04, 2014 12:57 PM PTLast Updated: Sep 04, 2014 1:02 PM PT


Imperial Metals now says nearly 25 million cubic metres of contaminated water and mine waste spilled into surrounding waterways, about 78 per cent more than the first estimates. That total includes:

  • 10 million cubic metres of water.
  • 13.8 million cubic metres of tailings slurry.
  • 0.6 million cubic metres of  construction waste from the dam.

But the company's vice-president of corporate affairs, Steve Robertson, said repeated testing has proven the water in the area is safe to drink, and he's been drinking it while living in nearby Likely.  (ANOTHER BOLD FACED LIE)
