#Syria: enough to fill 43 Olympic swimming pools per minute. The #Euphrates Dam opened its 4th spillway gate earlier today - for first time in recent history - to cope with incoming water discharged from Turkish Dams. It's now releasing 1,800 m³ per second into the river.

Retaining walls must incorporate drainage systems to prevent water pressure built up behind the wall from causing structural failures.

Anchor Lake Dam near Picayune, MS. Earthen dam being overtopped with the water still rising. NWS issued a PDS Flash Flood Emergency for areas downstream in case of catastrophic failure. Thanks to Jordan Hall for the heads up. Jonathan Petramala

Over the top (what you see in the video) That road on the very top is the dam’s crest [the highest point of the dam, where the road runs] - 1.78 km long (about 1.1 miles, or 17 football fields laid end to end). Imagine standing at one goalpost and looking across 17 full fields in a row - that’s the length you see. The crest sits at ~645 meters above sea level [the height compared to sea level]. Just below that is the reservoir’s normal full level [the usual maximum water height] at ~640 m - picture a massive lake stretched out behind you, nearly as high as the road itself. In the center of the main dam, the crest crosses a 216-meter bridge over the spillway opening [the structure that lets extra water out safely]. From this video angle, you might not see it clearly - but trust me, the spillway is there. Back to the bridge: it’s about 11.6 meters wide, wide enough for two cars or trucks to pass with space to spare. It rests on five reinforced-concrete piers [thick vertical supports made of concrete and steel]. Those five “openings” under the deck aren’t separate spillways - they’re the bridge supports holding it up. The “middle ramp” under the crest Now, let’s talk about the middle ramp. Picture a wide, stepped ramp running down the face of the dam beneath the bridge - that’s the auxiliary ungated spillway [an extra water-release path without gates], also called the middle spillway. It’s like the dam’s backup path for water when the main spillway is already in use. It only runs when the reservoir is at or near full and incoming water is more than the main spillway can release. Think of it like the overflow lip on a bathtub - it’s dry most of the time, but when the tub fills to the brim, the water flows over this edge. Its design discharge [maximum flow] is ~2,800 m³/s - roughly 1.1 Olympic swimming pools every second (1 pool ≈ 2,500 m³). Imagine an entire Olympic pool tipping over every single second and rushing down those concrete steps. How GERD handles floods You might be wondering - how does the dam actually manage floods? Well, it’s got a layered system [multiple ways to release water safely]: • Main gated spillway (left bank): six giant gates, ~14,500 m³/s capacity - about 5.8 Olympic pools per second pouring out. •Auxiliary ungated spillway (center): runs when the lake is high enough to overflow it. •Emergency spillway (saddle dam): for rare, extreme floods [about a 1,000-year event - the biggest flood expected in that time]. Together, these can pass a Probable Maximum Flood [worst-case possible flood] of about 30,200 m³/s. • Two low-level outlets (main dam): controlled releases [water pipes with gates that can be opened and closed] up to ~830 m³/s - that’s 830,000 one-liter bottles of water each second. Quick comparisons to bring the numbers to life • Crest length (~1.78 km): about a 20-minute walk from one end to the other. • Crest elevation (~645 m): the truck in your video is driving at a height equal to two downtown high-rises stacked above the riverbed. • Main spillway (~14,500 m³/s): enough to fill 6 Olympic pools every second in a major flood. • Auxiliary spillway (~2,800 m³/s): enough to fill 1.1 Olympic pools each second. • Low-level outlets (~830 m³/s): equal to 830,000 bottles of water rushing out every second. That truck isn’t just driving on a road - it’s crossing the crown [topmost part] of one of Africa’s largest dams, built to control floods, store water, and power the future. Above is the two-lane crest, and below, the spillways and outlets wait quietly until it’s time to release the river’s force. #Ethiopia #BlueNile #Hydropower #Engineering #BenishangulGumuz #Spillway #CrestBridge #GERD #RenaissanceDam

We are managing record amounts of water from the French Broad, Nolichucky, and Pigeon Rivers flowing into Douglas Dam, holding that water back to protect downstream areas like Knoxville, Lenoir City, and even Chattanooga. In a controlled manner, we are releasing a record amount of water, over 450,000 gallons per second, using the dam's generating turbines and spillway gates. Douglas, one of our largest tributary dams, is stable and secure.

Queenslanders won't have access to the Federal Government's new national emergency alert system. Despite Monday's test reaching 94 percent of its targeted cell towers, the LNP are choosing to opt out even when their own system has a history of failures. #Emergency #Alert #Qld #Disaster

Egypt is expanding the Toshka spillway and its lakes in the far south of the country to accommodate excess water resulting from Ethiopia’s unilateral management of the Grand Ethiopian Renaissance Dam (GERD). Toshka Lakes can take in around 56 billion m³ of surplus Nile water.

Zimbabwe's second-largest interior dam, Lake Mutirikwi, continues spilling. The dam supplies irrigation water to the Lowveld cane plantations and also generates 5MW of electricity. 📹: George Maponga

Keystone Dam releasing approximately 43,640 cubic feet of water per second, a little over 1-acre foot per second, into the Arkansas River, near Sand Springs, OK, July 7, 2026. Storage in the lake was 699,976-acre feet, which could fill AT&T Stadium to the dome 293 times.

⚠️(Nolichucky Dam Update)⚠️ The Nolichucky River has crested, and the dam remains intact. Water is currently receding by approximately one foot per hour. Our Dam Safety teams are in the process of assessing the condition of the dam to determine next steps. We are estimating water levels reached 8 feet over the record elevation.

An average 6,000 liter water truck serves at most 3,000 people. That’s two liters per person, the very very below minimum that each person in Gaza has access to per day. The 2-5 liters that people live on, barely surviving on. Translating Falasteen (Translating Falasteen (Palestine)) x The Sameer Project distributed 322,000 liters of clean water on June 15 to areas in the North. Donate to our Food and Water Campaign. Other ways to donate include: (Paypal option, please make sure to add a message saying "WATER") (Venmo option, please make sure to add a message saying "WATER")

We have a problem with water tanker mafias in the city. When we took a decision to reduce our use of water tankers these mafias, with riffles, attempted to prevent access to hydrants. The City is in the process of procuring its own water takers for emergency supply. We are appearing before CoGTA joint Parliamentary committee this afternoon. City of Tshwane
