Built in 1927, the dam generates about 3 megawatts of power at peak production, which is enough electricity to power 1,000 to 1,200 homes. Spencer Dam, according to Spencer, received regular maintenance, and in 2015, two so-called “toe drains” were installed to drain water coming through the dam. Just a little over a quarter-mile upstream, the 92-year-old Spencer Dam was straining to contain the swollen, ice-covered Niobrara River after an unusually intense snow and rainstorm.

In the Duero System the arch-gravity dam of Aldeadávila, 140 m high, and the double-curvature dam of Almendra, 202 m high, were built in this period. And NPPD didn't yet know why Spencer Dam failed, though a helicopter carried a crew to the site Friday to examine what remained. The 88-year-old hydro unit at Spencer Dam is capable of generating only 3 megawatts of electricity, or about the equivalent of one wind turbine. On March 14, 2019, the Spencer Dam on the Niobrara River in Nebraska, which was 90 years old, broke due to heavy rain and flooding. Spencer Dam in March 2019 after it failed during a flood Photo: Nebraska Department of Natural Resources via AP The results of a two-year investigation by the Associated Press (AP) were published this week and the findings were shocking — nearly 1,700 dams located in 44 states and Puerto Rico were rated as “high-hazard” dams that are in poor or unsatisfactory condition.

spencer michels: Nevertheless, a year ago, spurred on by the drought, Californians approved a $7.5 billion water bond that requires spending $2.7 billion on water storage. They were working last week, he said. If there was a place in Northeast and North Central Nebraska not affected by flooding by Thursday morning, it would have been the lucky exception to the rule. They were in a race with the rapidly rising Ru River to save the dam and the millions of people that lay sleeping downstream.

This section of the site contains information on dam ownership and how the owners are responsible for the safety and the liability of the dam and for financing its upkeep, upgrade and repair.Although most infrastructure facilities, such as roads, bridges and sewer systems are owned by public entities, the majority of dams in the United States are privately owned.

NPPD’s entire production capacity is about 3,100 megawatts. It is part of the hyrdoelectric plant built in 1927 and operated by the Nebraska Public Power District. Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. On the night of Aug 8, 1975, a line of people frantically piled sandbags atop Henan Province's Banqiao Dam while being battered by the worst storm ever recorded in the region. Overwhelming ice and water breached the Spencer Dam just south of Spencer at approximately 5:30 a.m. A double-curvature dam was the first selection, but the high floods made them opt for the arch-gravity type. The dam is called Spencer Dam.

It was a race they were about to lose. Unfortunately, that didn’t take into account a 92-year-old earthen dam [the Spencer dam] on Nebraska’s Niobrara River, where something called a bomb cyclone ruined the dam, releasing a wall of water onto farms and pastures, washing away crops and livestock, and finding its way into Gavins Point dam at the forefront of Missouri River flood control. And it was in transition.

Built in the late 1920s and owned by the Nebraska Public Power District since the early 1970s, it could still generate electricity when the utility needed it.

It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, … The Boyd-Holt E-911 center received a call from Nebraska Public Power District employees that the dam had been compromised and Highway 281 bridge also was in danger. Tim Gokie, chief engineer of the state’s dam safety program, said that ice, carried by epic floodwaters, most likely caused the 92-year-old concrete-and-earthen dam to wash out last month, rather Dams are designed and built based on the state of the watershed at the time, Delatte notes.

The first was finished in 1963 and is located in an impressive granite canyon formed by the Duero river.
