Along with the Blanchard Dam ten miles downstream, Little Falls Dam was purchased by Minnesota Power during the 1920s. In 1978, automation for Blanchard, along with the Sylvan and Pillager dams on the Crow Wing River, were centralized in Little Falls; this allowed a staff of four to do work that had previously required sixteen operators. Lock and Dam No. The ambitious Mississippi project, however, relies on relatively unproven technology. Dam No. Bob is a 40-year veteran (yes, he is grizzled) who edited one Pulitzer Prize winner and wrote two that were nominated. It is on track to hit a target of 85 percent carbon-free power by 2030, said Xcel spokesman Matt Lindstrom. This station was built in 2008-09 and came online on April 9, 2010. As is typical with many great accomplishments, however, construction of the Keokuk plant encountered disappointments and seemingly insurmo… Sorry, your blog cannot share posts by email. Hydropower has a long history in the Pacific Northwest and particularly in the Columbia River Basin. The six mainstem dams on the Missouri River support 36 hydropower units with a combined plant capacity of 2,436 megawatts (MW) of potential power generation. See our full terms of use Mississippi River Power Corp. is the generation side of the former Almonte Hydro. [2] The Little Falls Manufacturing Company faltered due to a number of factors, including "the ill effects of the economic depression that swept the frontier and ultimately the nation in the late 1850s." A new dam was completed in 1888 as a means to redevelop Little Falls, and this created jobs and attracted immigrants to the town. Few, if any, major American cities have such sources in their downtown areas. 2. The U.S. Army Corps of Engineers has proposed selling the dams because they are no longer needed for river navigation. But Superintendent John Anfinson points out that the three hydroelectric plants satisfy a small part of the state’s electricity needs. Nile River - Nile River - Dams and reservoirs: In 1843 it was decided to build a series of diversion dams (barrages or weirs) across the Nile at the head of the delta about 12 miles downstream from Cairo, so as to raise the level of water upstream to supply the irrigation canals and to regulate navigation. The original natural falls had a drop of only about five feet. The proposal to sell the dams, he said, is in uncharted waters. (Scott Takushi / Pioneer Press). here. The first hydroelectric dam in the Pacific Northwest was built in Spokane in 1885. OPG tracks water levels and flows with water level gauges at stations and dams across our hydro operations.

PAUL - Andy Davis can think of 42 reasons not to take out the dams of the upper Mississippi River. James Green, along with a group of co-partners, was the owner of the first dam, a wing dam built on the east channel of the falls. Mississippi is getting closer to producing hydropower for the first time. Wind and solar generation rise and fall with the weather and time of day, but river power is as steady as the Mississippi itself. Indeed, Minneapolis was built on that location because of river power — mechanical force that first powered flour mills. The three plants produce 42 megawatts of electricity an hour, which is about 368,000 megawatt hours a year. [3] William Sturgis and James Fergus left their Little Falls business interests in the hands of their wives while they went west in search of gold. The plant was built in 1924, and Brookfield purchased it in 2008. Maybe it would be gas-burning,” said Davis. >> The plant was built in 1924, and Brookfield purchased it in 2008. What is the trade-off?”. “Maybe it wouldn’t be a green facility. Ontario Power Generation operates 66 hydroelectric stations, including a green power portfolio of 29 small hydroelectric plants, and 241 dams on 24 river systems. The water action looks impressive in these spring high water level photos. If the dams were removed to restore the Mississippi to its original free-flowing state, that source of electricity would be jeopardized. (Scott Takushi / Pioneer Press), Mike Summers stands in the control room of the hydroelectric plant on the Mississippi River, formerly owned and operated by the Ford Motor Company, now owned by Brookfield Renewable, Sept. 27, 2018. The U.S. Department of Energy estimates non-power dams like this, used to aid navigation, could support up to 12 gigawatts of new hydroelectric capacity. What did the Mississippi River look like before the locks and dams? The impounded water now reaches to the Belle Prairie Rapids, west of the Belle Prairie Church, about 3.5 miles upstream.

The company built a larger dam, sawmill, cabinet shop and bridge and owned about 2,000 acres (8.1 km2) of land. [1], William Sturgis bought the dam and, with Calvin Tuttle and James Fergus, formed the Little Falls Company, later called Little Falls Manufacturing Company. Xcel’s hydroelectric plant at that site generates 14 megawatts. The story of this chapter in Little Falls history is told through letters written between James and his wife Pamelia in the book "The Gold Rush Widows of Little Falls" by Linda Peavy and Ursula Smith. Further improvements were made from 2005 to 2010. But Brookfield’s Davis said that the dams’ locations are valuable. Below the dam, the river's elevation is 750 feet (230 m).

Advocates for removing the dams say the river could become a recreational magnet, drawing boaters, kayakers and inner-tubers. [6] The larger additional power house was built to house two additional generators, with a third generator being added during the 1980s. Wind turbines also could replace the megawatts generated by the three plants. The largest power plant and dam in the world at the time, Keokuk was considered an engineering marvel. The faster flow also would benefit aquatic life, they say. Another advantage, Davis said, is reliability. The uppermost lock and dam on the Upper Mississippi River is the Upper St. Anthony Falls Lock and Dam in Minneapolis.

Cloud Dam is the largest city-owned hydroelectric facility in Minnesota! Four dams located in Mississippi’s Yazoo River Basin – on Arkabutla, Sardis, Enid and Grenada Lakes – will be retrofitted in the next two to three years to produce enough power for more than 15,000 homes annually. The operation has since been remotely controlled by Minnesota Power's central dispatchers in Riverton, and the dam is now staffed only by maintenance personnel. Brookfield owns an 18-megawatt plant there. Construction on the west wing was underway by 1918. They are popular resting spots for migratory birds. If that happens, the new owner could remove them — and let the waters of America’s biggest river flow freely through a six-mile canyon. By 1890, the population more than quadrupled, reaching 2,354 people. The dam, including a new power house, was completed by 1921. Because generating electricity by water power has little overhead and no fuel costs, this relatively small 4.5 megawatt dam remains economically profitable. Construction of the fourth Little Falls dam, this one made of concrete, started with the east wing in 1914. Stagnant reservoir pools disorient migrating fish and can significantly increase the duration of their migration. As you comment, please be respectful of other commenters and other viewpoints.

The locks and dam located here are part of a much larger system of 29 locks and dams on the Upper Mississippi River. If Mississippi dams are removed, what happens to the hydroelectric plants? The two dam sites share another concern — elimination of hydroelectric generation. 1 to capture the river’s hydroelectric power. Any replacement facility, he said, also would not be as environmentally beneficial. Xcel is working to switch its power generation from fossil-fuel plants to renewable power. [5]. PETER THOMSON, LA CROSSE TRIBUNE ARCHIVES That is the number of megawatts generated by hydroelectric generators between Minneapolis and St. Paul.

Amid climate change, green activists are beginning to warm again to the benefits of hydroelectric power, despite the harm it can do to the environment. It’s more efficient to have power generated nearby, said Davis, because of “line loss” from transporting power over distances. The Corporation of the Town of Mississippi Mills owns 100% of the shares in MRPC. Dams can also alter the timing of flows.
