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.

Lewis River ~ Including Clear, Quartz, Siouxon, Pine, Rush, Smith Creeks & the Muddy River
Photo by Susan Saul Wild and Scenic Rivers Support Local Communities The legendary volcanoes in southwestern Washington and the spectacular rivers that originate on their slopes are valuable to the health, economy, and cultural identity of local communities. Rivers like the Green, Cispus, and Lewis provide drinking water to thousands of local residents, world-class recreation, and a high quality of life for local residents. Designating the rivers and key tributaries in Volcano Country under the Wild and Scenic Rivers Act will increase long- term potential for recreation and tourism in the area, ensure cool clean water for fish and people, and protect these natural treasures for future generations. Just a few of the benefits of Wild and Scenic designation include: RECREATION, TOURISM, AND THE ECONOMY: According to the Outdoor Industry Association, outdoor recreation brings in more than $11.7 billion annually to our state, supports an estimated 115,000 jobs, and generates $650 million in annual sales tax revenue. Travel and tourism provide nearly 8000 jobs – or 14 percent of jobs across all economic sectors – in Lewis, Cowlitz, and Skamania counties. In addition to putting a river “on the map” for visitors and outdoor enthusiasts, a Wild and Scenic River designation can lead to access improvements and foster growth in river-based outdoor recreation and tourism. For example, a recent study of the Wild and Scenic section of the Rogue River found that commercial rafting, fishing, and other recreation contributed $30 million a year to the State of Oregon’s economy. The White Salmon and the Klickitat River are two positive examples of Wild and Scenic Rivers in Washington that benefit local recreation economies. -

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. -
