The Nisqually River Project includes the LaGrande Dam, which was first built in 1912, and the Alder Dam, built in 1945. The Cowlitz River Project includes the Mossyrock and Mayfield dams. Tacoma Power operates four hydroelectricity projects, three of which are made up of more than one dam. The Mossyrock Dam is on Bonneville Power’s grid, meaning that it is one of many contributors to electricity used by states throughout the Northwest. As the utility both creates and distributes electricity, some of those jobs are folks who spend their days watching the power market, calculating earnings and costs of production versus output. Tacoma Power - which is just one of the Tacoma Public Utilities along with Tacoma Water and Tacoma Rail and was formerly called Tacoma City Light - is a cost-of-service organization that employs around 800 people. Tours and demonstrations were provided on the following days. On May 16, 1969, over 1,200 people gathered for a three-day long dedication of the Mossyrock Dam. Sundbaum also said contractors built “the fastest cableway ever used in dam construction” to move all that concrete. For context, a single cubic yard of concrete weighs 4,050 pounds. The project required the placing of more than 1.25 million cubic yards of concrete in total. The contractor set a new world record for concrete placement: 102,000 cubic yards in one month. So, here are some followup factoids about the dam, which is the tallest in Washington at 606 feet from bedrock to the top.Īs spokesperson Monika Sundbaum put it, “when the (Mossyrock) dam was completed in 1968, it was a truly impressive feat of engineering and construction.” To read more about that, click here or see the Thursday, June 23, edition of The Chronicle.Īs it happened, even a 1,300 word-story could not summarize all the worthwhile facts about the dam, its design and construction. 1 of Jefferson County v.By Isabel Vander Stoep / Tuesday, The Chronicle toured the Mossyrock Dam with a hydro mechanic and staff from from Tacoma Public Utilities, the owner of the dam and beneficiary of the power it produces. The award recognizes Tacoma Power's "exceptional creativity, leadership and achievement in the pursuit of energy efficiency." The utility competed against other utilities and organizations served by BPA in Washington, Oregon, Idaho and Montana. In 2011, Tacoma Power received the first-ever Award for Excellence in Energy Efficiency from the Bonneville Power Administration (BPA). Its first independent power generation came with the construction of LaGrande Dam on the Nisqually River, 36 miles away from the city, producing hydroelectric power as of November, 1912. Tacoma City Light was created in 1893 when the citizens of Tacoma voted to buy the privately owned Tacoma Light & Water Company to ensure its safety and longevity. The flume was mostly uncovered and attracted thirsty cows and children in search of a good wading pool. The water was transported to the city through a 10-mile wooden flume that emptied into an in-town reservoir. Wright's system drew water from Tule and Spanaway Lakes and Clover Creek. Wright was granted the exclusive right to create Tacoma's first power and water company, incorporating the Tacoma Light and Water Company. It is a division of the Tacoma Public Utilities and owns the Click! Network, developed by Steven Klein, Tacoma Power's former superintendent.
