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.

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."

15 villages inundated as dams collapse at Kalapara

Published : Sunday, 22 October, 2017

PATUAKHALI, Oct 21: At least two dams at Kalapara upazila collapsed inundating about 15 villages, for which around 2,000 people became stranded.
The dam located at Lalua union in Kalapara upazila collapsed after two months of its construction due to unusual high tide water flow.
The eight places of the flood control dam have been breached due to unusual high tide of the Ramnabadh River on Thursday night. As a result, a good number of houses and 3,000 acres of crop land went under water. The fishes of ponds and enclosures were washed away.
Locals alleged that the inferior quality of construction work is behind the collapse of the dyke. The Dhulashor Dyke is also at risk as a portion of it was already damaged. The villagers doubt that the remaining portion of the dyke will be damaged soon.  The high tide water flooded the Nizampur,. Yousufpur, Komorpur and Shudhirpur villages through the damaged dyke of Nizampur village under Mohipur union. The Aman paddy of 5000 acres of land went under water.
The Water Development Board built the dyke at Lalua union on an urgent basis spending Tk 75 lakh in the current fiscal year to save the locals from suffering. But the dam collapsed within two months. So the Pashurbunia, Charipara, Nowapara, Gazirkhal, Munshipara, Banatipara, 11 No Hawla, Dhonjupara, Choto Pach No, Baro Pach No, and Chowdhury Para villages were flooded. The water-logged people are leading a miserable life. The farmers are afraid of losing their crops.
Shila Begum of Banatipara said, "We could not sleep at night;  I was sitting taking grandson on my lap."
Housewife Ruma Begum said, "The tidal water washed away our burner; so we could not cook in the afternoon; my children could not eat anything, and there is no way to go anywhere. The roads also went under water."
Farmer Bashir Gazi said the crops of his land went under water as the dam collapsed. His house also went under water.
Farmer Abul Bashar said the fish of his enclosure was washed away.
The sources concerned said, the emergency protective dyke at Mirabari point was damaged by tidal water on Thursday and Friday. Major portion  of the dam adjacent to the sea has already gone under water. Six villages beside  the Ramnabadh River and four villages of Mohiupur have been flooded with water. Kuakata is also at risk.
Baliatoli UP Chairman ABM Humayun Kabir said a culvert has collapsed due to pressure of the tidal water at Charbaliatoli.
Water Development Board Executive Engineer Mohammad Abul Khayer said the weather is very rough; necessary steps would be taken after visiting the sites. Ten villages in the upazila become inundated, and people are water-logged. Payra Port and the adjacent ghats have been asked to show the cautionary signal number 3.

Puerto Rico's Guatajaca dam failing amid mass evacuations and flash flooding

The flooding comes following the second major storm to devastate the Caribbean this hurricane season


pr-flood.jpgRescue workers splash through flood waters in Puerto Rico 

A failing dam in Puerto Rico endangered tens of thousands of people and left officials scrambling to conduct mass evacuations on Friday.

"This is an EXTREMELY DANGEROUS SITUATION. Buses are currently evacuating people from the area as quickly as they can," the National Weather Service (NWS) in San Juan said in a statement.

Authorities were reportedly trying to save some 70,000 people.

There have been 13 deaths on the island since Hurricane Maria ripped through the Caribbean, leaving the entire US territory without power for the foreseeable future. The governor said that Maria was the worst storm Puerto Rico had seen in a century.

The dam, which is located at the northern end of Lake Guajataca in northwest Puerto Rico, forced NWS to send a series of tweets urging residents to get out of the path of the water.

The agency urged people to move to higher ground. Federal reservoir data shows that the lake rose more than three feet between Tuesday and Wednesday when the category 4 storm smashed into the island.

"This is an extremely dangerous and life-threatening situation. Do not attempt to travel unless you are fleeing an area subject to flooding or under an evacuation order," the agency said in that alert.

The dam is used for drinking water and irrigation in Puerto Rico. It was built in 1929, and had a capacity of 11 billion gallons in 1999, according to the US Geological Survey.

Maria came in quick succession after Hurricane Irma made its way through the Caribbean and up into Florida just weeks ago. Irma also hit Puerto Rico with strong wind, heavy rains, and knocked out power and communications for most of the island.

The storm is now a category 3 hurricane, and is moving away from the Turks and Caicos Islands. It is expected to head northeast and east of the Bahamas over the weekend, according to forecasts.

So far, 30 people have been reported dead from the storm in the Caribbean from Maria. That includes at least 15 deaths in Dominica, where a further 20 people are missing.

After Maria hit Puerto Rico, President Donald Trump said that the tempest had "totally obliterated" the island, and promised to help rebuild Puerto Rico.
