Orcas rely on salmon for up to ninety percent their diet, but these fish are in rapid decline. Our communities and future generations need and deserve both. Removing the four lower Snake River dams and restoring a free-flowing river will reduce the impacts of global warming on salmon and steelhead and help ensure a healthy, sustainable future for wild pacific salmon and the communities that depend upon them. A growing flood threat exists to the cities of Clarkston and Lewiston because of the four lower Snake River dams. Why Breach? Since 1975 when the eight dams (four on the lower Columbia River and four on the lower Snake River) were completed, return rates have only rarely exceeded the 2 percent survival minimum. Raising levees, dredging, and other measures will cost millions of dollars over the long term and pose threats to fish, wildlife and recreation opportunities. Further, cost-effective investments in conservation (efficiencies) that can generate an additional 850 average megawatts (enough for a city like Portland OR) are also clearly achievable. When it comes to gauging the potential for new sources of truly clean, renewable energy, study after study finds that the region -- especially if one includes Wyoming and Montana -- contains tens of thousands of megawatts of clean wind power at fairly low cost. The Lower Snake River Project features four locks and dams in the state of Washington: Ice Harbor Dam, Lower Monumental Dam, Little Goose Dam, and Lower Granite Dam. 4. Advocates hope to have the dams out by 2024 . 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. Scientists predict that the salmon and steelhead of the Snake River that are born at high altitudes where cooler temperatures will persist have the best chance of surviving the current warming trend. Since this time the Lower Snake River has been used as a means for getting products to markets. If the dams are removed, how will farmers who use these dams’ reservoirs to ship in crops in barges deliver their products to market? Naturally occurring sediment coming down the Snake River, is piling up behind Lower Granite dam and raising the level of the river. Why do scientists support salmon and steelhead restoration by removing the 4 lower Snake River dams? Further downstream are Little Goose Dam, Lower Monumental Dam, and Ice Harbor Dam. We can retire the dams and keep the lights on. The issues on the Snake River are a major gushing wound that require serious attention, not a simple paper cut that a bandaid could handle. The answer is simple: The federal government’s salmon plans have failed because they circumvented legal requirements and politicized science. Here’s how: The low-cost estimate ($80 million, see Question 2 above) for replacing the four lower Snake River dams’ power is based on creating 90 percent of this new energy through investments in conservation (efficiency) and 10 percent from new, truly clean, salmon-safe renewable energy like wind or biomass. Sheldon told colleagues at a January 31 public hearing that agriculture in the basin relies on the irrigation provided by these dams, in addition to the Clarkston-Lewiston Port, for transporting their produce to market. 6. Without this action, it is difficult to fathom the suite of actions that would indeed meet these same obligations. Those benefits include increased commercial fishing, a resurgence of recreational jobs and businesses, and a substantial reduction in the expensive, wasteful (and largely ineffective) salmon programs now in place. The salmon were, and continue to be, so important to these peoples that their governments were willing to give up the rights they had to large tracks of land in order to ensure that salmon graced the waters of this region forever. It is a false choice. Each year more than $550 million in funding, more than twice that of even Everglades restoration, goes to NOAA Fisheries, the Army Corps of Engineers and other federal agencies for this effort. The Corps admits that the volume of sediment is too vast for dredging to solve the problem. From 1994 to 2004, they ranged from 0.35 to 2.5 percent, exceeding 2 percent in just a single year. The bottom line: the limited power produced by the four lower Snake River dams can be replaced without adding to our climate pollution, at little or no cost to consumers, and with great benefits to endangered salmon and the communities, businesses, and cultures that rely upon them. 7. Fishery scientists have monitored Snake River wild salmon population declines since the 1950s. 1. 11. In the latest plan, for example, the federal government treated dams as unchangeable parts of the environment, much like a mountain. The current recovery plan is too expensive and promises not fish recovery, but decades more in multi-billion dollar spending. LSR Freight Transport graph . Subject: President Obama: Protect Orcas by Removing Four Lower Snake River Dams Hi, President Obama is considering taking bold, needed action that would help to save orcas (killer whales) in the Pacific. Although this study demonstrates … 3. Initial studies conclude that the economic benefits of salmon and steelhead recovery exceed the costs to replace the dams’ seasonally-limited power. Shipping statistics from Ice Harbor indicate water-born commerce peaked on the lower Snake in 1995 and has been on a long, steady decline ever since. The Endangered Species Act lays out certain basic principles and requirements to ensure that we do not inadvertently allow species to go extinct. As a federal court found in 1994, the federal hydrosystem is calling out for a “complete overhaul” not just the tweaks and minor adjustments the federal government seem willing to provide. Investments in a modern rail system and improved highways is not only affordable, it will provide far more benefits to the region’s farmers, businesses and communities that the lower Snake River barge system does. Are the 4 Lower Snake River dams next? In the early days skilled steamboat operators carefully navigated both the Columbia and Lower Snake rivers in order to transport wheat and other goods to Portland. Taxpayers could be liable for billions to tens of billions of dollars in compensation payments to treaty tribes and Canada if the fish go extinct. Further, Northwest consumers should not bear even this minimal expense alone. Each year, 3 million cubic yards of sediment enters the reservoir, raising the water level and increasing risk of flood. 2. An independent economic analysis recently rein- … Download the PDF on fishing and salmon numbers. They cited modeling by the Environmental Protection Agency that shows that removing the four lower Snake River dams would reduce Snake River water temperatures by 6.3 degrees F, on average, during the summer and early fall. Ice Harbor Dam is lowermost of the four lower Snake River dams and therefore offers the best indication of the entire waterway’s economic viability. Why have the federal government’s salmon recovery efforts failed, despite more than $8 billion spent? The four dams on the lower Snake River are part of a vast and complex hydroelectric power system operated by the federal government in Washington, Oregon, Idaho and Montana. Below is a list of commonly asked questions about Columbia and Snake River salmon and the four lower Snake River dams with answers from regional stakeholders. Over the last two decades, federal agencies have spent more than $8 billion in failed attempts to restore Columbia and Snake River salmon. The role that dams and reservoirs, habitat, hatcheries, harvest, predators and the ocean play in salmon survival is well understood. Americans are ready for effective solutions to one of the toughest natural resources challenges of our day. The four lower Snake River dams can generate enough electricity to power the entire city of Seattle. As the answers to Questions 3 & 6 (above) indicate, the Northwest is blessed with an abundance of cost-competitive clean energy answers to our power needs. Restoring this national treasure and valuable natural resource is the joint responsibility of all Americans. As the Columbia and Snake Rivers were populated with dams and other forms of habitat destruction, opportunities to fish have been severely reduced. The lower Snake River dams have enabled large quantities of grain to be shipped by barge from Lewiston, Idaho all the way to the mouth of the Columbia River, 465 miles away, making the ninth-largest city in the nation’s 39th most populous state the West Coast’s farthest-inland port. Dams – blocking the river’s flow and creating large stagnant reservoirs have especially impacted the salmon’s ability to flourish. Can we replace the dams’ power with clean energy? The four lower Snake River dams are Ice Harbor, Lower Monumental, Little Goose, and Lower Granite. Wheat, barley and other crops are destined for Portland, OR and then exported overseas.

4 lower snake river dams

What impact does fishing have on Columbia and Snake River salmon and steelhead survival? A key benefit for Snake River populations is the amount of high quality habitat they have that is not found in the other Columbia basins. Lower Granite is now 55 percent full of sediment and the river level has now risen higher than downtown! And it would devastate fishing communities from California to Alaska and into Idaho. The U.S. Army Corps of Engineers has developed and constructed fish cooling systems at Lower Granite and Little Goose dams to alleviate warming water concerns. What can Congress do to solve this problem and restore salmon and steelhead to abundance? The four Lower Snake dams were the last built in the federal Columbia hydropower system. The federal government wants to keep the Four Lower Snake River Dams in place. It is caught in the ocean and the lower Columbia River where it mixes with other abundant populations found on the lower Columbia River. People have been fishing for, sustained by, and enjoying salmon for centuries. A Long Legal Fight for the River Over the past 25 years, conservation and fishing groups have gone to court challenging federal agency hydropower systems operation plans that failed to protect threatened and endangered salmon in the Columbia River basin. How does global warming affect Columbia-Snake River salmon and steelhead survival?

Tribal, state and federal fisheries biologists have all supported the removal of the four lower Snake River dams as a keystone action necessary for any valid salmon plan. Yet one simple fact remains: not all dams are created equal. The Lower Snake River Dams Power Replacement Study confirms that clean and renewable resources can provide a viable and effective energy alternative to the continued operation of the dams. All replacement portfolios resulted inannual LOLP values . The loss-of-load probability, or LOLP, indicates the likelihood that resources will not be adequate to serve load in the region. Lower Granite Dam, one of the four dams on the Lower Snake River that are driving all remaining Snake River salmon toward extinction. The confluence of the Snake and Columbia rivers at Burbank, Washington is part of Lake Wallula, the reservoir of McNary Dam. The short answer is “YES!” In the Northwest right now, generating “new energy” through investments in conservation is cheaper than generating new energy from coal or other fossil fuels. The four lower Snake River dams can operate above their rated capacity to produce up to 3,483 MW for several hours. Replacing the dams’ power with energy efficiency (conservation programs) and truly clean, salmon-safe, renewable energy is estimated to cost between $80 million and $180 million a year – just 2-4 percent of Bonneville Power Administration’s (BPA) $4 billion annual budget. The Northwest would not be what it is today without hydroelectricity from the region’s dams. Their actual yearly output is just over 1,000 average megawatts, or about what a city of size of Seattle or Milwaukee or Denver or Louisville uses. Do these dams provide any flood control? Because these dams can’t provide flood control and have virtually no storage capacity, they can reach that maximum for just a few days in any year (during a rapid spring snowmelt for example). The study also offers a framework from which the federal agencies can draw as they develop a new plan for dam operations. The draft EIS identifies and evaluates a no-action alternative and five alternatives, one of which includes breaching the four lower Snake River dams. Crops and other products will be railed and trucked to Pasco, WA where they can be loaded onto barges, or continue to Portland by rail. Substantial amounts of relatively inexpensive geothermal power are also available in Idaho, Utah and most likely in southern Oregon. Wild salmon and steelhead in the Columbia and Snake Rivers are an important part of the Pacific Northwest’s history and heritage, and economy and culture. What can Congress and the President do to solve this problem and restore salmon and steelhead to abundance? More on Climate Change. Snake River fall Chinook is the one exception. During the past few decades Inland Northwest local railroads—called short lines—have fallen into disrepair, with serious economic consequences for struggling farm communities, local business owners and manufacturers. sierraclub.org. The four Snake River dams on the lower Snake in southeast Washington were completed in the 1960’s and 1970’s. Prior to the dam building era that began in the early 1900s, salmon were commercially caught at high rates in the Columbia River. Instead of following this species protection law, the federal government has ignored its requirements, reinterpreted them in inconsistent and dangerous ways, and attempted to rewrite them. Federal agencies that manage the dams released their Columbia River System Operations Draft Environmental Impact Statement Friday morning. The dams became operational between 1961 and 1975. Lewiston community leaders are opposed to raising levees, which will cut the town off further from it’s rivers and disrupt popular bike path and walking paths. Arnold Schwarzenegger’s popular and successful “Million Solar Roofs” program could be instituted in the Pacific Northwest as well. How to Breach the 4 Lower Snake River Dams with a Pile of Policy Papers and Two D-8’s •Prepared by Jim Waddell Civil Engineer, PE USACE Retired + = Rev: Feb 2018. The higher power replacement cost estimates are based on greater percentages of renewable energy.

Orcas rely on salmon for up to ninety percent their diet, but these fish are in rapid decline. Our communities and future generations need and deserve both. Removing the four lower Snake River dams and restoring a free-flowing river will reduce the impacts of global warming on salmon and steelhead and help ensure a healthy, sustainable future for wild pacific salmon and the communities that depend upon them. A growing flood threat exists to the cities of Clarkston and Lewiston because of the four lower Snake River dams. Why Breach? Since 1975 when the eight dams (four on the lower Columbia River and four on the lower Snake River) were completed, return rates have only rarely exceeded the 2 percent survival minimum. Raising levees, dredging, and other measures will cost millions of dollars over the long term and pose threats to fish, wildlife and recreation opportunities.
