The 100-foot (30 meter) tall dams generate electricity, provide irrigation and flood control, and allow barges to operate all the way to Lewiston, Idaho, 400 miles from the Pacific Ocean. The U.S. government announced Friday that four huge dams on the Snake River in Washington state will not be removed to help endangered salmon migrate to the ocean. They contend the dams must go if salmon are to survive. They take almost one-fifth of a year to swim from the Pacific to Redfish Lake, much of it in summer’s hottest water – and eat nothing. On the way to the ocean, juvenile salmon can get chewed up in the dams’ turbines. Your feedback will go directly to Science X editors. The salmon populations in Idaho were so abundant that in the 1950s, before the construction of the four lower Snake River dams, recreational anglers on the Middle Fork of the Salmon River could catch and keep up to two salmon a day over a season that stretched months. The four dams are part of a vast and complex hydroelectric power system operated by the federal government in Washington, Oregon, Idaho and Montana. Scientists warn that southern resident orcas are starving to death because of a dearth of chinook salmon that are their primary food source. The Columbia River system dams cut off more than half of salmon spawning and rearing habitat, and many wild salmon runs in the region have 2% or less of their historic populations, according to the Center for Biological Diversity. The Snake River has over 20 major tributaries, most of which are in the mountainous regions of the basin. ``We are proud to see a comprehensive, science-based process come to fruition.''.

Scientists warn that southern resident orcas are starving to death because of a dearth of chinook salmon that are their primary food source. For five decades, the four dams on the lower Snake River have provided water for irrigation, emissions-free hydroelectricity, and 140 miles of flat water for barge passage from Pasco, Washington, to Lewiston, Idaho. Now, 13 salmon runs are listed as federally endangered or threatened. The lower Snake River dams produce roughly 1,100 average megawatts of carbon-free electricity compared to the Klamath River dam’s 78 average megawatts. The four dams are part of a vast and complex hydroelectric power system operated by the federal government in Washington, Oregon, Idaho and Montana. Conservation and fishing groups say the federal government’s newest plans to manage dams and protect salmon is inadequate. The plaintiffs in the new lawsuit claim that will not be enough to restore salmon and steelhead populations. The dams effectively prevented all but a few salmon from carrying out some of nature’s most astonishing migrations, reaching spawning grounds in Idaho’s Snake River Basin as far as 900 river miles from the Pacific Coast and more than a mile in elevation. There are many reasons why Sockeye Salmon in the Snake River are reduced in number. In 1999, activists bought an ad in The New York Times claiming that unless the dams were removed, “wild Snake River spring chinook salmon … will be extinct by 2017.” When 2017 arrived, the Snake River Chinook population was six times larger than in 1999. Since then, salmon populations have plunged. Oregon Gov. Entering the Columbia River from the ocean, the naturals transform from saltwater to freshwater fish while swimming 925 miles up-current in the Columbia, Snake and Salmon Rivers.
