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 break in Washington triggers life-threatening flash flood emerg...
Thousands of Americans are under a life-threatening flash flood warning after a dam failed in Washington on Monday.
County dispatch reported the breach of the Green River Levee, south of Seattle, prompting the National Weather Service (NWS) to issue an alert at 11.51am PT.
A dozen counties, including Clallam, Grays Harbor, Jefferson, King, Kitsap, Lewis, Mason, Pierce, Skagit, Snohomish, Thurston and Whatcom, should brace for flooding over the next several days.
The NWS urged locals to move to higher ground immediately, warning: 'Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles.'
Residents and businesses east of the Green River in the Orillia area in Tukwila, Renton and Kent are under a Level 3 (Go Now) evacuation notice. People in that area should go north or south, officials said.
The NWS said over 46,000 people could be impacted, along with two schools and one hospital.
Officials believe the levee failure is tied to days of intense rainfall, with another round of heavy rain expected Monday that could bring up to 12 inches in some areas.
The NWS said flash flooding is already underway and described the damage threat as 'considerable.'
'In coordination with King County, we have issued a FLASH FLOOD WARNING for a levee breach in Tukwila, WA, near Todd Blvd. Water is likely moving north toward I-405,' the agency said in a post on X.
The region is also being impacted by a Pineapple Express, a storm system carrying warm, moisture-laden air from near Hawaii.
AccuWeather meteorologists said steady rain will focus on higher terrain, particularly the Olympic Mountains, Coastal Range and Cascades, with two to four inches expected and a Local StormMax™ of 12 inches on windward slopes.
Additional rainfall on already saturated ground raises the risk of mudslides and worsening runoff through midweek.
Multiple rivers in western Washington are already experiencing minor to moderate flooding, with forecasts calling for further rises.
'Several inches of additional rain this week, on top of last week's totals, can lead to renewed major flooding,' AccuWeather meteorologist Alex Duffus said, 'including on rivers that recently crested at record levels.'
He added that rivers may take several days to crest even after the rain tapers off.
AccuWeather Senior Meteorologist Alex Sosnowski said: 'Expect multiple, rapid rounds of moderate to major flooding of the short-run rivers in the higher and intermediate elevations of the Cascades this week.
'Flooding in the higher elevations can occur in a matter of a few hours. However, where these rivers reach lower, flatter terrain just above sea level, moderate to major flooding can be delayed and longer-lasting and perhaps up to a few days. Multiple crests are likely.'
An atmospheric river is a long, narrow tract of the atmosphere that gathers moisture from the tropics and sweeps it toward the poles.
The Pineapple Express is a well-known example, originating in the tropical Pacific near Hawaii.
Meteorologist Jeff Berardelli of WFLA-TV (Tampa Bay) warned on X that the storm could deliver 'pockets of 12–18 inches of rain and flash flooding' across the West Coast over the next two weeks.
Residents should remain vigilant through the week, as saturated ground and rising rivers will prolong the risk of floods and landslides even after the storm moves on.
