  • Cowlitz/Riffe Lake Level Fact Sheet June 6, 2017
    Cowlitz/Riffe Lake Level Fact Sheet June 6, 2017 Based on new information about regional seismicity, the United States Geological Survey (USGS) revised its earthquake predictions for the Cowlitz River basin. Although the probability of a large earthquake is very low, the revisions showed an increase to the potential impact on the spillway piers of Mossyrock Dam (not to the dam structure itself). To protect public safety, Tacoma Power has proposed to hold Riffe Lake’s elevation down approximately 30 feet lower than full (778 ft.) at least into the next decade. Formal approval by the federal agency that regulates the utility is pending. Public safety Public safety is our top priority. Although there is a very low probability of the type of seismic activity that would cause the spillways to fail, we have a responsibility to operate in a way that limits the risk to the public. Keeping the lake level lower Mossyrock Dam’s five spillway piers accomplishes that. There are no modifications to the operations at at full lake level Mayfield Dam. If we get significant rain or flooding, Tacoma Power may need to use the storage capacity of Riffe Lake to minimize downstream flooding by temporarily allowing the lake level to rise. After the risk of downstream flooding passes, we would then gradually lower the reservoir. Seismic information Mossyrock Dam is a tall, double curvature arch with spillways located high in the middle of the dam. No concrete arch dams have failed due to earthquakes. However, preliminary analysis concluded that specific seismic events could cause the spillway piers to fail, which could cause the spillway gates to fail, resulting in an uncontrolled release of water and considerable downstream flooding.

  • 2010 Integrated Resource Plan
    2010 Integrated Resource Plan August 2010 Prepared by Power Management Direct Comments/Questions to (253) 502-8025 Tacoma Power 2010 Integrated Resource Plan Executive Summary Tacoma Power’s 2010 Integrated Resource Plan recommends conservation as the sole addition to the utility’s resource portfolio. Analysis indicates that an aggressive conservation acquisition program coupled with Tacoma Power’s existing resources will be sufficient to meet projected retail load. This strategy should allow the utility to avoid a need to purchase expensive generating resources for over ten years. Specifically, this IRP found that: • Approximately 63 aMW of new conservation is cost-effective in Tacoma Power’s service territory over the next ten years. • This conservation, when combined with current utility resources should be sufficient to serve projected retail load beyond 2020. • Tacoma Power is well positioned to comply with the 3 percent renewable resource mandate that begins in 2012. Tacoma Power’s eligible renewable resource portfolio is comprised of nearly equal parts of utility owned incremental hydro and a contract for renewable energy credits. The 2010 IRP also considered the potential effect of electric vehicles and climate change on utility operations: • Electric vehicles are unlikely to impose a significant load on Tacoma Power until 2018 to 2025. • The effects of climate change are likely to be small for Tacoma Power’s loads and resources through the mid-2020s. This assessment is preliminary – the findings are likely to evolve as our understanding of the regional implications of climate change improves. Page: iii TACOMA POWER 2010 INTEGRATED RESOURCE PLAN EXECUTIVE SUMMARY The primary purpose of preparing an meet any identified load-resource gap at integrated resource plan (IRP) is to the lowest cost and risk.

  • Cowlitz River Advisory Board to Provide Input to WDFW Regarding the FHMP
    Hydroelectric facilities at Mayfield and Mossyrock Dam (Hydroelectric Project) are owned and operated by City of Tacoma, Washington, Department of Public Utilities, Light Division (Tacoma). In August of 2000 the Cowlitz River Hydroelectric Project Settlement Agreement (Settlement Agreement) was completed. The Settlement Agreement establishes Tacoma’s obligations for the protection, mitigation and enhancement of natural resources affected by the Hydroelectric Project. The Settlement Agreement called for the development of a Fisheries and Hatchery Management Plan (FHMP). Issues addressed in the FHMP include quantity and size of fish to be released, rearing and release strategies to be employed, stock status monitoring and evaluation programs and fishery management strategies. The initial FHMP was completed in August 2004. The Settlement Agreement calls for the FHMP to be updated every six years, and that update process is now beginning. Actions called for in the FHMP can impact both conservation efforts and fishing opportunities in the Cowlitz Basin. Washington Department of Fish and Wildlife (WDFW) will be working with other signatories to the Settlement Agreement to develop an FHMP that achieves conservation and sustainable fishery goals. To help WDFW better represent our constituents we will work with a Cowlitz River advisory board to provide input to WDFW regarding the FHMP. WDFW’s goal is to complete an updated FHMP that better addresses the needs of the resources and citizens of the State of Washington. To that end, WDFW is currently in the process of developing this Cowlitz River advisory board that will be composed of concerned citizens who will provide recommendations to the department regarding changes to the FHMP and other fishery management issues in the Cowlitz Basin.

We are a division of Tacoma Public Utilities, which is governed by a five-member Public Utility Board. We were established in 1893 when the citizens of Tacoma voted to buy the privately-owned Tacoma Light & Water Company. Local citizens believed that public ownership and local control would give them a higher caliber of services and the ability to maintain control over them. That decision paved the way for us to become a national leader in providing renewable, reliable, and affordable electricity. Today, we generate, transmit, and distribute electricity and provide energy services in an increasingly competitive marketplace. We provide electricity to nearly 179,000 homes and businesses across 180 square miles in the cities of Tacoma, Fircrest, University Place, Fife, parts of Steilacoom, Lakewood, Joint Base Lewis-McChord, and unincorporated Pierce County as far south as Roy. 6 • 2020 INTEGRATED RESOURCE PLAN WHERE YOUR POWER COMES FROM Nearly all of the electricity we deliver to our customers comes from Our resources usually provide more electricity than we hydroelectric power sources.

  • Harris Hydraulics Laboratory Historic Resources Addendum University of Washington
    Harris Hydraulics Laboratory Historic Resources Addendum University of Washington James Cary, Architect pc 14 December 2012 1. INTRODUCTION Background The University of Washington is planning a project to replace the roofing on the Harris Hydraulics Laboratory (HHL). The laboratory consists of two structures – the original building built in 1920 and an addition built in 1961. The proposed project will replace the roofing on the original 1920 building, the 1961 addition, and the 1961 connector between the two. In addition, the proposed project scope includes improvement of safety measures on the roof by installing safe access and fall arrest anchors. The Harris Hydraulics Laboratory is located on the south portion of the University of Washington campus on San Juan Road, which is adjacent to the building on its northwest and southwest sides. Adjacent buildings are the Oceanography Teaching Building (OTB) to the northwest and the South Campus Center (SOCC) to the southeast. Showboat Beach is located across San Juan Road to the southwest. The University’s Historic Preservation Policies and Practices require a Historical Resources Addendum (HRA) to be prepared for any project that makes exterior alterations to a building more than 50 years old (2003 Seattle Campus Master Plan). This report provides documentation of the historical and architectural features of both the original Harris Hydraulics Lab (1920) and the addition to the building (1961). These structures are 92 and 51 years old, respectively. This HRA was developed by James Cary, Architect pc of Seattle, Washington. The research was undertaken in October 2012 and a second draft report was prepared for 30 October 2012.

  • Cowlitz/Riffe Lake Level Fact Sheet Feb. 14, 2017
    Cowlitz/Riffe Lake Level Fact Sheet Feb. 14, 2017 The Cowlitz River Project produces hydroelectric power from the water stored behind Mayfield and Mossyrock dams. Completed in 1962, Mayfield Dam forms 13-mile-long Mayfield Lake. Mossyrock Dam, built in 1968, stands 606 feet above bedrock and is the tallest dam in Washington state. The dam forms 23.5-mile-long Riffe Lake. Based on new information about regional seismicity, the United States Geological Survey (USGS) recently revised its earthquake predictions for the Cowlitz River basin. Although the probability of a large earthquake is very low, the revisions showed an increase to the potential impact just on the spillways of Mossyrock Dam (not to the dam structure itself). To protect public safety, Tacoma Power has proposed to hold Riffe Lake’s elevation down approximately 30 feet lower than full (778 ft.) at least into the next decade. Approval by the federal agency that regulates the utility is pending. Please note: The circumstances at Mossyrock Dam are significantly different than the current situation at Oroville Dam in Northern California. Tacoma Power is not reacting to a current situation – the operational changes are an abundant precautionary measure. There is no impending emergency at Mossyrock Dam and there is no structural damage. Without a significant seismic event, which has a very low probability, there are no concerns about Mossyrock Dam. Mossyrock Dam is a concrete structure, while the Oroville Dam is an earthen structure. The spillways at the Oroville Dam sit on soil and bedrock, and are failing. At Mossyrock, the spillways rest on concrete, and, even when applying the revised seismic analysis, it is not predicted that an earthquake would compromise the dam – it would only impact the spillways.
