Freight volumes on the lower Snake have declined 69% over the last twenty years, and container freight shipped from the Port of Lewiston in Idaho has declined 93% over the last sixteen years. The dams create an impediment to fish migration and worsen the warming of river water, which also inhibits migration. Lower Snake River (LSR) Freight Transportation is in Long-term Decline. What it means is that every 20 linear feet worth of loaded containers counts as a single TEU. When demand for energy is high in summer and winter, the dams only contribute small amount of power, as shown for Lower Granite Dam, it’s potential is reached at 100-200 MW. The four dams in particular question are Ice Harbor, Little Goose, Lower Granite and Lower Monumental. Wild salmon and steelhead populations have tremendous historical, cultural, ecological, and socio-economic value as well. On the lower Snake River in southeastern Washington, it bridges Whitman and Garfield counties. The Snake River basin and where the salmon (used to, and again, will) swim. The Snake River dams in Washington would remain in place under a final study released Friday, July 31, by federal agencies. The cost-benefit analysis was controversial then, and still is today. Topics: Hydropower, Navigation, Irrigation, Fish Passage, Costs. The draft EIS identifies and evaluates a no-action alternative and five alternatives, one of which includes breaching the four lower Snake River dams. By the 1990’s, lower Snake River Coho were extinct, and lower Snake River spring Chinook, fall Chinook, and steelhead were listed as threatened or endangered under the Endangered Species Act. The dams generate a negligible amount of power, and it will be cheaper to take them out than to update them to modern standards.” No fish= No orcas ! The American taxpayer continues to heavily subsidize operation, maintenance, and repairs on the four lower Snake River dams. We can build new rail lines, new roads, and new water infrastructure. At the heart of this issue are the cumulative, negative impacts of the four dams on the lower Snake River, a major Columbia River tributary, which has severed fish passage to rich spawning habitats in Idaho. The Four Lower Snake River Dams Improving Salmon Passage, February 2002 Army Corps of Engineers, Walla Walla District; The Snake River is the principal tributary to the Columbia River, draining approximately 109,000 square miles in Idaho, Wyoming, Utah, Nevada, Washington, and Oregon. The cost of maintaining the lower Snake River waterway is growing rapidly. Due to the lack of water storage, the dams also don't offer much in the way of irrigation. As a result, salmon populations have declined by more than 90%. Today even this projection is proving too optimistic. 3. Lower Snake River Hydropower Has Already Been Replaced. Lower Granite Dam is actually regarded to increase flood risk to Lewiston, Idaho. Tell our Northwest congressional delegation that we need them to lead on a robust economic development package that takes down the lower four dams and rebuilds our northwest economy. The department of fish and wildlife manages the 26 facilities that release millions of salmon a year. Lower Granite Dam is located approximately 40-miles downstream of Lewiston, Idaho. By 2000 that volume had dropped to 4.52 million tons, and in 2014 the lower Snake waterway transported only 2.8 million tons. Today the lower Snake River dams (LSRDs) preform various functions; providing hydropower, navigation, irrigation and fish passage. The four lower Snake River dams are a major cause.2 Recovery measures for wild salmon costing billions of dollars have failed. They are particularly valuable in times of extreme hot and cold weather, when demand for electricity peaks. These dams will be breached in the future due to the economics. The federal agencies rejected the removal of these dams, despite broad scientific and stakeholder consensus that doing so may be the only way to recover Snake River salmonids. It is time for the lower four Snake River dams to come down. “The science is clear that removing the earthen portions of the four lower Snake River dams is the most certain and robust solution to Snake River salmon and steelhead recovery,” Brown wrote. Flows in the lower Snake River are highest in the spring (average annual peak of approximately 165,000 cubic … Most of the power generated by the dams occurs during the spring (snowmelt) when demand and prices are low. They argued that damming the free-flowing lower Snake River would decimate wild fish runs. You can read more about it. Kate Brown said removing the four lower Snake River dams in Washington state is the most certain way to boost salmon and steelhead recovery in the Columbia Basin. The Clearwater Basin of North Central Idaho provides excellent habitat for wild salmon and steelhead. Four aging dams in Washington state block passage along the lower Snake River, a major migration corridor linking pristine cold water streams in central Idaho to the mighty Columbia River and out to the Pacific Ocean. They are “run of the river” dams with very little storage capacity and are thus almost totally dependent on the amount of snowpack and rate of runoff. A focus of the EIS will be the lethal warmwater reservoirs created by the four lower Snake River dams. Economic Tradeoffs of Removing the Lower Snake River Dams. Below are FOC’s comments. “Extensive evidence indicates that breaching the four lower Snake River dams would provide more certainty of achieving the kind of long-term … Bonneville Power Administration bears almost all the costs of maintaining these functions, except for navigation, which is paid for by the federal government (taxes). Free-flowing … • Breaching the four lower Snake River Dams per the Court’s strong admonition that such an alternative be considered in detail in the CRSO FEIS (MO3); • Maximizing spill for the benefit of ESA-listed salmonids (MO4); and • The Preferred Alternative, based on a flexible spill strategy designed to allow for adjusting operations to allow for achieving the best balance among the System’s many … Generation is limited by both spill requirements and seasonal river flow. Janet Higbee-Robinson, Bellingham Advocates hope to have the dams out by 2024 . Free-flowing … 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. Freight transportation has declined drastically as the combination of trucks and railways have become more efficient than trucks and barging. The new plan says that’s the best option for fish – but too expensive in terms of irrigation, transportation and power generation. A reanalysis of the 2002 Lower Snake River Juvenile Salmon Migration Feasibility Report demonstrates the Army Corps’ Walla Walla District underestimated the average annual cost of keeping the lower Snake River dams in place by a staggering $160.7 million. The Wild Clearwater Country is the northern half of the Big Wild, which contains the largest remaining roadless, and undeveloped stretch of wildlands left in the lower 48 states. Wild salmon advocates, tribal representatives and renewable energy advocates, who support removing the four Lower Snake River dams in southeastern Washington, say this decision will hurt salmon and the orcas that depend on them for food. The Army Corps of Engineers has spent $600 million dollars over the last thirteen years for System Improvements, intended to improve fish passage for imperiled wild salmon and steelhead populations. Congress did not authorize flood control as a purpose and the dams were not designed for it. Once they are released, they are subject to similar undesirable conditions as wild fish are, as they migrate through the system to and from the Ocean. We now have excellent examples of indisputably successful dam removal and river restoration projects: the Elwha and Glines Canyon dams on the Elwha River of Washington state, Condit Dam on the White Salmon of Washington state, four dams on the Penobscot River in Maine and Marmot Dam on the Sandy River in Oregon. The Lower Snake dams have always been controversial, wrote Idaho historian Keith Petersen in his 1995 book about the dams, “River of Life, Channel of Death.” None of this includes the $782 million the Bonneville Power Administration spends annually on fish mitigation (hatcheries, barging smolts, etc.). With several large sawmills in the region, the Port of Lewiston has not shipped any lumber for at least seven years. Lower Granite Lock and Dam is a concrete gravity run-of-the-river dam in the northwest United States.On the lower Snake River in southeastern Washington, it bridges Whitman and Garfield counties. Its six dams on the main stem of the Columbia River provide all the electricity its contracted customers need; the electricity generated by its 25 other dams, including the four lower Snake River dams, is all surplus. The Draft EIS for Columbia and Snake River salmon is out for public comment. The 2009 Washington State Marine Forecast projects the growth of freight transportation on the lower Snake from 2003-2030 to be 0.3 percent. Costs for operation and repairs currently exceed power revenues and economic benefits derived from navigation and irrigation. In addition to normal maintenance and operations, and sediment management planning costs, dredging recently cost more than $23 million for the upper part of the Lower Granite pool, with more implementation costs to follow. Lower Monumental Dam on the Snake River in Washington is one of four dams considered for removal or breaching in a long-running debate. They are “run of the river” dams with very little storage capacity and are thus almost totally dependent on the amount of snowpack and rate of runoff. Due to sediment build up, Lower Granite Dam actually creates a flood risk to Lewiston, Idaho and requires conveyance dredging to mitigate this risk. The plan guides dam management on the Columbia River System, which includes the four controversial Snake River dams. The Snake River basin and where the salmon (used to, and again, will) swim. Its first 50 miles (80 km) run through Jackson Hole, a wide valley between the Teton Range and the Gros Ventre Range. “From 2015 to 2017, the Fish and Wildlife Service authorized the lethal removal of Doublecrested Cormorants in the Columbia River estuary. A free-flowing river could greatly improve wild salmon and steelhead populations in the Clearwater Basin, and deposit nutrients throughout the basin’s ecosystem. Over the span of fifty years, wild Chinook salmon populations virtually ceased in the basin, while wild steelhead struggled to navigate the fish ladder(s) and populations plummeted. The four dams generate less than 3% of the power produced in the Pacific Northwest. The plan guides dam management on the Columbia River System, which includes the four controversial Snake River dams. Survival of juvenile fish through the hydro system is only 50%, and smolt-to-adult return ratios (from the ocean) remain well below levels required for recovery of threatened and endangered wild Snake River salmon and steelhead. Study suggests breaching the lower Snake River dams benefits the economy – February 2016. It’s simply a matter of time before the federal agencies admit it. The judge’s order led to federal hearings throughout the region, ending earlier this … It rejects dam breaching arguing that such a dramatic approach would destabilize the power grid, increase overall greenhouse emissions and more than double the risk of … Earlier today, a long-awaited federal report on the prospect of removing the four lower Snake River Dams was released, offering little hope for the watershed’s endangered wild salmon and steelhead. Corrected Cost and Economic conclusions based on Corps data and planning processes show breaching via channel bypass has benefits ranging from 4 to 20 to 1 with Regional effects adding more than 5K jobs in E. Washington and Lewiston. The current use of this savings figure by ports and special interest organizations is unsubstantiated propaganda. The proposed removal of four Lower Snake River dams has been the subject of legal battles since 1991. Further downstream are Little Goose Dam, Lower Monumental Dam, and Ice Harbor Dam. Through the turbines, letting water over the spillway (there is mandatory spill the court has ordered to aid salmon passage), through the fish ladders (adults), through the juvenile fish passage system (where they enter a small orifice upstream and are counted as they travel through the pipe to the other side) and finally they utilize barges and trucks to transport juveniles downstream. In addition to direct taxpayer costs, the many benefits lost from maintaining this project—from vastly improved sports and commercial fisheries to alternate investment in a transportation system that can benefit a much wider range of businesses — make the early removal of the four lower Snake River dams imperative. Problems inherent in the huge slack water reservoirs created by the dams cannot be fixed. Geology. A 2014 study by the Lewis Clark Valley Metropolitan Planning Organization cited rail improvements and construction of a unit train loader at the Port of Lewiston as the number one priority for improved transportation in the Lewiston area. Sea lions gather at the mouth of the Columbia waiting for the salmon, and some are intelligent enough to detect the barges and trucks that will release their next meal. Study suggests lower Snake River dams not critical for Pacific Northwest energy capacity – June 2015. To make up for the declining runs, hatcheries are subsidized, and this is another large expense for BPA called “mitigation”. This controversial recovery method is at odds with the migratory bird act. Though they have a high capacity, it is seldom realized. Irrigation pumps could be replaced and pipes extended to the Snake River for farmland irrigated behind Ice Harbor Dam. For more graphs, click on the below headline. Whether the dams … Climate change is adding another challenge as warming water temperatures in the reservoirs behind the dams threaten salmon which depend on cold water and snowmelt. Idaho Congressman Mike Simpson flirted with backing the removal of the four lower Snake River dams during a conference here on salmon recovery Tuesday. The cost of mitigation hatcheries for lost Snake River stocks is rising a rate of 5 percent annually, and turbine rehabilitation over the next 15 years will require at least $775 million in today’s dollars. The debate regarding the potential removal of the four Lower Snake River dams in Washington has been ongoing for over two decades, but much of the existing information is either outdated or incomplete. The four dams in particular question are Ice Harbor, Little Goose, Lower Granite and Lower Monumental. Indeed, it is a river system that binds their very culture. 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. Two unit train grain terminals have come on line in eastern Washington in the last 11 years, and a third is being built west of Spokane and will be fed in part by short lines that penetrate the Palouse Prairie. The Snake River basin and where the salmon (used to, and again, will) swim. Opened 46 years ago in 1975, the dam is located 22 miles (35 km) south of Colfax and 35 miles (56 km) north of Pomeroy. Data source: Port of Lewiston (portoflewiston.com). FOC comments on Columbia Hydropower EIS-4-6-20. 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 lower Snake River project is economically unjustifiable and fiscally unsustainable. The nameplate capacity of the 4 lower Snake dams totals 3,033 Megawatts, but over the past 11 years they have only produced an average of 961 aMW (annual Megawatts), or 33% of nameplate capacity. The four lower Snake River dams are important to the Northwest’s power needs, provide important support for the transmission system and help keep our system low in carbon emissions. 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. Since 2000, container-on-barge traffic on the lower Snake River has declined by 82 percent, with more than half of that decline occurring prior to the great recession, which commenced in fall 2008. Below the tourist town of Jackson, the river turns west and flows through Snake River Canyon, cutting through the Snake River Range and into eastern Idaho. Economic benefits of the dams are far below the costs (benefit to cost ratio of .15, meaning 15 cents in benefits to every tax dollar spent). Further mitigation: In the past few years, BPA has begun culling and disturbing sea lion and birds. Oreg on’s Democrat Gov. The outcome of the EIS will affect some of the West’s most historic steelhead rivers, including Snake River tributaries like the Grande Ronde River in Oregon and the Clearwater River in Idaho. Over the past 20 years the volume of freight transported on the lower Snake River has declined by 69 percent. Despite these factors and hundreds of thousands of voices supporting the removal of the four lower Snake River dams, including Oregon’s Governor Kate Brown, the three federal government agencies (Army Corps of Engineers, Bureau of Reclamation, and Bonneville Power Administration) rejected dam removal altogether in their draft Environmental Impact Statement (DEIS). U.S. District Court Judge Michael Simon in 2016 ordered dam managers to consider removing or altering the four Lower Snake River dams. We can build new rail lines, new roads, and new water infrastructure. Large public enterprises including Bonneville and the Corps would change how they do business. and at anytime may contribute to the  ~8,000 MW surplus sold  on secondary markets – also known as interchange or tier 2 power sales. The dams do not provide flood protection or any meaningful amount of irrigation. With the support of elected officials, the Corps has the authority and the time to update the 2002 EIS now and still act this year. The Walla Walla District’s claim in its 2014 Lower Snake River sediment management plan that the lower Snake River waterway provides cost savings of $8.45 per ton is false. The Walla Walla District derived this figure from the 2002 Lower Snake River Juvenile Salmon Migration Feasibility Report, which claimed a savings of $5.75 per ton, a figure based on an earlier study of shipping volumes on the deep draft section of the Columbia River downstream from Portland. Further downstream are Little Goose Dam, Lower Monumental Dam, and Ice Harbor Dam. About … On a broader scale, such consideration lays the analytical groundwork for potential later consideration of a determination to breach one or more of the four Lower Snake River dams. “Even PacifiCorp now supports dam removal. Reality: The four lower Snake River dams are relatively unreliable sources of power compared to some other dams in the federal Columbia River system. container shipments down drastically at Port of Lewiston. I urge readers to join the Nez Perce and advocate for the restoration of the Lower Snake River basin. Now, the operation of those four dams — Ice Harbor, Little Goose, Lower Monumental, Lower Granite — is under reconsideration. Washington State is investing in bridge improvements so these short lines can service heavier cars at higher speeds. It is time for the lower four Snake River dams to come down. Wild salmon and orca whales are threatened with extinction owing partly to the presence of four hydroelectric dams on the lower Snake River in Washington. It receives the Hoback and Greys Ri… The widely-celebrated removals of these large dams has reduced taxpayer waste and restored fisheries, injecting additional dollars into rural economies. Together they create approximately 140 miles of slackwater, and made Lewiston, Idaho the “farthest inland seaport” on the west coast. sierraclub.org. The Lewiston Dam was built approximately 4-miles upstream from the confluence of the Clearwater River and lower Snake River in the 1920’s. Over the next fifteen years, all twenty-four turbines for the lower Snake River dams will need to be rebuilt. Compelling evidence proves dams kill salmon. The Snake River basin and where the salmon (used to, and again, will) swim. Economic Tradeoffs of Removing the Lower Snake River Dams The debate regarding the potential removal of the four Lower Snake River dams in Washington has been ongoing for over two decades, but much of the existing information is either outdated or incomplete. Lower Granite Lock and Dam is a concrete gravity run-of-the-river dam in the northwest United States. The four Lower Snake River hydroelectric dams are the low cost, carbon-free backbone of Oregon’s power supply and essential to meeting our region’s renewable energy goals. 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. The four lower Snake River dams are Ice Harbor, Lower Monumental, Little Goose, and Lower Granite. Oregon Gov. Fish and Wildlife. For example, Clearwater Paper, Lewiston Idaho’s largest employer, is located 2 miles from the Port of Lewiston and exports paper and paperboard. Large public enterprises including Bonneville and the Corps would change how they do business. The reservoirs have flooded out the natural river flows and riparian habitat, destroyed spawning grounds and rearing habitat, decreased river flow, and exposed juveniles to a host of aquatic … The Army Corps of Engineers recently acknowledged an annual cost of $7.6-$12.6 million just for operations and maintenance of the waterway. To reduce river temperature, the Army Corps must make major changes to its management of the Lower Snake River dams. Fish passage at the dams can happen a couple ways. Restoring the lower Snake River by removing the four dams that block its flow would precipitate changes in the region’s physical infrastructure, electric grid operations, carbon emissions, grain transport, irrigation, recreation, fish habitat, and riverine and marine ecosystems. There is currently an energy surplus in the Pacific Northwest. For more graphs, click on the above headline. As the federal agencies become more desperate to recover salmon, we must hold them accountable to stop the use of this method, and start seriously considering breaching. Clearwater Paper now ships 95 to 100 percent of its product by truck and rail. They are part of the problematic aging U.S. infrastructure that requires more money for maintenance every year. The four Snake River dams on the lower Snake in southeast Washington were completed in the 1960’s and 1970’s. The Port of Lewiston’s container shipments peaked in 1997 with 17,611 TEUs and have been on a long, steady slide ever since. Freight transportation on the lower Snake is so low that the waterway falls into the Corps’ category of a river of “Negligible Use.”. The proposal to build the four lower Snake River dams drew strong opposition, particularly from state and federal fish biologists. Native wild salmon and steelhead populations have called this place home for millennia. Despite objections, Congress approved construction. 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. The confluence of the Snake and Columbia rivers at Burbank, Washington is part of Lake Wallula, the reservoir of McNary Dam. Over the past 18 years, freight volume has declined 69 percent, and container shipments from the Port of Lewiston, the only port on the river that ships containers, had dropped at least 82 percent by early April 2015—and 100 percent by late April 2015. Lower Granite Dam is located approximately 40-miles downstream of Lewiston, Idaho. The Lower Snake River Project's four dams and navigation locks have transformed this part of the Snake River into a series of reservoirs. Unfortunately, none of this has worked, less and less wild fish return each year (see salmon and steelhead for more metrics). Wind and solar are a growing part of our clean energy system and hydropower from dams works together with them to meet demand and provide reliable carbon-free power when the wind isn’t blowing and the sun isn’t shining. The four lower Snake River dams can generate enough electricity to power the entire city of Seattle. More than 5,000 cormorants were removed and more than 6,000 nests were destroyed.” – Letter from NPCC to U.S. The plan guides dam management on the Columbia River System, which includes the four controversial Lower Snake River dams — Ice Harbor, Lower Monumental, Little Goose and Lower … The salmon-killing dams of 0 percent growth from 2002-2030 has proven to be much optimistic.
