Smart Investments Now Will Benefit EntireRegion for GenerationsThe Tualatin Basin Water Supply Project is an investment in the health and sustainability of the region’s watershed, economy and community. Direct benefits of the project include:
Economic Development Washington County is the economic engine of the state, generating more state revenue than is returned to the area. A reliable, secure and cost-effective water supply is essential to the continued economic health of the region.
Watershed Health Sustaining the overall health of the Tualatin River Watershed is a primary goal of local water resource agencies. Adequate instream flow is a major factor in maintaining water quality and fish habitat. Two fish species in the Tualatin River are listed as threatened under the federal Endangered Species Act. Restoration of fish habitat will require more water.
Community Livability Quality of life is directly related to the region’s economy and sustainability. Residents of Washington County value the beauty, quality and recreational opportunities afforded by the area’s natural environment. The region must continue to maintain and enhance a distinctive quality of life to attract talented workers.
Water is Key to Long-term Regional VitalityAs the economic engine of Oregon, the businesses, farmers and residents of Washington County need dependable, safe and secure fresh water resources to ensure the long-term economic health and livability of our region. These inter-related sectors are responsible for about one-fourth of Oregon’s economy and major employers reasonably expect that the Federal and local authorities will diligently pursue repairs and/or other measures necessary to ensure a safe, secure and reliable source of water.
Local water resource agencies in the Tualatin Basin are working together to plan for diverse, safe, and resilient water supplies in order to meet the needs of our growing region. Concurrent with the Tualatin Basin Water Supply Partners’ efforts to secure Scoggins Dam, Washington County’s primary water source, major municipal water suppliers have modified the water intake at the Willamette River Treatment Plant and are building a new treatment facility near Sherwood to meet increasing community water needs. Together these projects will help secure our future.
Working Together for Public Safety and Water SecurityProtecting public safety and meeting the region’s future water needs are central to the Tualatin Basin Dam Safety & Water Supply Joint Project. Clean Water Services (CWS) and the Tualatin Project repayment contractors are working closely with Bureau of Reclamation under joint project authority secured in the Consolidated Appropriations Act, 2016 (P.L. 114-113) to integrate Scoggins Dam safety modifications with increased storage in order to protect against a major earthquake, secure the region’s primary water source and meet the long-term municipal, agricultural and environmental water needs of our region. Addressing dam safety concurrent with increased storage funded by local beneficiaries will enable federal, state and local agencies to leverage their shared investment to protect public safety and meet the 100-year water needs of the community in the most cost-effective and efficient manner possible.
“The region’s future is tied to our ability to plan for and deliver fresh, clean water to every home, farm and business while restoring flow to the river.”
Former Chair Andy Duyck,Washington County Commission
Other Project BenefitsHenry Hagg Lake, formed by Scoggins Dam, is a critical component of the region’s long-term water supply and a major regional asset. Project benefits of a secure and expanded facility include: • Public safety and water security • Agricultural irrigation: Irrigates 17,000 acres of the state’s most productive farmland, producing more than 50 different crops • Water conservation and supply: Provides drinking water for 400,000 people • Jobs and economy: Supports 283,000 jobs at more than 18,300 businesses in Washington County including Intel, Genentech, SolarWorld and Nike • Water quality and habitat restoration: Restores flow to the Tualatin River providing critical habitat to fish and wildlife • Flood management • Recreation: More than 900,000 visitor days annually

Joint Project Examines Two Locations for Safety Modifications and Water SupplyReclamation and CWS are working together under the Joint Project authority to consider design concepts that will address dam safety and meet the long-term water needs of the community. In 2018, Reclamation and CWS will continue the engineering and environmental review of several concepts at two primary locations:
• Strengthen the existing dam: Reclamation is leading the dam safety engineering and environmental review of strengthening and raising Scoggins Dam in its current location.
• Construct a new downstream dam: CWS is coordinating the engineering and environmental review of the proposed new concrete dam downstream of Stimson Mill.
The goal of evaluating several concepts is to be sure that all cost-effective approaches have been explored before moving on to more detailed assessments. A downstream replacement structure could significantly reduce project costs for both the federal government and local stakeholders.
Shared Commitment to a Safe Secure Water SupplyFederal authorization for the Joint Project was secured in the Energy and Water Development Act, 2004 (P.L. 108-136). The Partners and CWS have invested more than $15 million in the Joint Project to protect the public and secure our region’s water supply. In 2017, CWS provided $5 million to Reclamation to fund geotechnical work, additional benefits analysis, and design concurrent with the dam safety improvements.
The Partners are prepared to move forward on the Joint Project. Under the Contributed Funds Act, CWS has the resources prepared to: • Expedite the feasibility and environmental review process; • Coordinate stakeholder engagement, property acquisition and public review process; and • Fund environmental review, final design, and construction associated with the additional benefits concurrent with the dam safety improvements.

Washington County, OregonWith a population of nearly 600,000, Washington County is the second-fastest growing county in Oregon, and the economic engine of the state—home to Intel, Nike, SolarWorld, Genetech and a vibrant agricultural economy. Safe, secure and reliable water resources are central to the state and region’s economic success and livability. The number of jobs on the westside has more than doubled in the last 20 years, reaching over 283,000. The westside has outpaced the rest of the Portland metro region in economic development and is a net exporter of earnings to the state.
“Scoggins Dam is a regional asset, and we consider this project critical for meeting water demands in our community, now and for the future.”
Mayor Steve Callaway,City of Hillsboro
Title TransferIn 2016, Reclamation encouraged the Tualatin Project repayment partners to reconsider the feasibility of transferring the Tualatin Project major works (Scoggins Dam, Hagg Lake and associated lands) from federal to local ownership. A previous Title Transfer assessment was completed in 2009, but set aside until the costs of the federal seismic obligations were more fully understood. The Partners are prepared to re-examine Title Transfer if there are cost and project delivery benefits to be accrued through local ownership and management of the facilities.

Scoggins named nation’s first “joint project”In late 2017, Reclamation set into motion a partnership with
CWS to evaluate dam modifications that can address both safety
and water storage capacity. This joint partnership between
Reclamation, a federal agency and CWS, a water resources
management utility, is the first of its kind in the nation. The
partnership enables Reclamation and CWS to conduct a more
efficient project that will meet multiple objectives and save
money for the federal government and local CWS customers.

Sustaining the economic vitality and environmental health of Oregon
Hagg Lake
APRIL 2016
In the next 20 years, the Portland metro region will need new, safe and secure water supplies to ensure Oregon’s long-term economic viability, environmental health and sustainability. Water needs in the Washington County’s Tualatin Basin alone are projected to double by 2050. The Tualatin Basin Water Supply Project is a basin-wide, integrated water resource management project that will secure the region’s water supply; help ensure we are able to respond to anticipated climate change and reoccuring drought cycles; and meet the 50-year water supply needs for: • Water quality and critical habitat improvements in the Tualatin River and its tributaries • Cities, industry and economic development • Agriculture
Fueling Oregon’s Economic Engine Hagg Lake/Scoggins Dam—a federal facility—is the central component of Washington County’s water supply and a major regional asset. Water from Hagg Lake supports nearly 250,000 jobs; provides drinking water for more than 400,000 residents; irrigates 17,000 acres of cropland; and sustains water quality in the Tualatin River to protect fish and wildlife habitat. The safety, security and reliability of Hagg Lake are essential to Oregon’s economic health.
