Basin Overview and Challenges
Basin Overview
• Basin size: 6,155 sq. miles • Irrigated cropland: 500,000 acres • Food processing industry: $2.3 billion • Agricultural production: $1.8 billion
Land Cover
Yakima Project Reservoirs
• Managed by Bureau of Reclamation
• Five reservoirs with 1 million acre-feet of capacity (average annual runoff 3.3 million acre-feet)
• Irrigation deliveries: 1.7 million acre-feet
• Snowpack is the “sixth reservoir”
Declining Water Supply
• Surface water is over- appropriated
• Droughts in 1992-1994, 2001 and 2005
• Proratable irrigation districts reduced to as little as 37% of allotments
• Instream flows greatly reduced by out-of-stream diversions
Reduced Fisheries
• Historic salmon and steelhead run size: 800,000 fish
• Average run size last 10-15 years: 15,000-20,000 fish
• Native sockeye and summer Chinook: Extirpated
• Native coho: Once extirpated, now reestablished
• Spring and fall Chinook: Seriously reduced
• Steelhead and bull trout: ESA Threatened species
Municipal and Domestic Needs
• Cities and Counties anticipate continued growth
• USGS Study showed connectivity with surface flows
• Most ground water rights are interruptible in dry years
Use of IWRM Principles
in the Yakima River Basin
Integrated Plan Grew from the YRBWEP Program

Goals of the Integrated Plan
• Provide opportunities for ecological restoration and enhancement, including fish passage
• Improve water supply during drought years (70% proratable supply)
• Provide for efficient and adaptable water supply management
• Contribute to sustainable economy and environment
Key Principles
• Improve outcomes for both society and the environment
• Build consensus among stakeholders • Combine a range of solutions • Evaluate joint outcomes • Consider change and uncertainty • Build in adaptability
The Integrated Plan: Projects and Programs
Seven Elements
• Reservoir Fish Passage • Surface storage • Groundwater storage • Enhanced conservation • Market Reallocation • Structural &
Operational Changes • Habitat/Watershed
Protection
Reservoir Fish Passage Element
• Provide upstream and downstream fish passage • Benefits:
– Provide access to high quality habitat – Increase anadromous species abundance – Allow reintroduction of sockeye – Provide genetic interchange for bull trout
Bumping Kachess
Keechelus Rimrock
Cle Elum
Surface Water Storage Element
Wymer Dam and Pump Station
• New off-channel reservoir, 163,000 acre-feet
Lake Kachess Inactive
Storage • Existing Reservoir: Access
200,000 acre-feet from inactive storage pool in dry years
Bumping Lake Enlargement • Replace existing dam to add
165,000 acre-feet
Proposed Wymer Reservoir
Groundwater Storage Element
Use surface water during periods of high runoff Recharge aquifers for later withdrawal
Enhanced Water Conservation Element
Agricultural Conservation – up to 170,000 acre-feet
• Lining/piping canals and laterals • Re-regulation reservoirs • Irrigation efficiency – reduce seepage,
evaporation, and spills Municipal and Domestic Conservation Program
• Promote efficient landscape irrigation practices
• Expand education/incentives to encourage voluntary efficiency
• Establish best practice standards
Market Reallocation Element
Near-term effort • Build on existing water market programs • Take steps to reduce barriers
Longer-term effort • Focus on water transfers between
districts • Allow fallowing within district, leases to
outside district • Requires substantial changes to existing
laws/policies
Structural and Operational Changes Element
• Keechelus-to-Kachess Tunnel or Pipeline
• Kittitas Reclamation District
canal modifications and new pump station
• Reduce power diversions at
Roza and Chandler Dams • Wapatox Canal improvements • Raise Cle Elum Lake by 3 feet
Habitat/Watershed Protection and Enhancement Element
• Three areas proposed for acquisition • 46,000 acres in Teanaway Basin • 15,000 acres in Yakima Canyon • 10,000 acres at Little Naches
headwaters • Consider protective designations on
public lands and waters • Mainstem Floodplain and Tributaries

Costs and Benefits
Costs of the Integrated Plan
• If Constructed All at Once: $4.2 Billion (Could range from $3.2 to $5.4 billion)
• 100-Year Cost in “Present Value”: $3.5 Billion
(Construction, O&M, and periodic replacement costs)
All costs expressed in 2012 dollars.
Ecological Benefits
• Improved stream flow conditions • Improved operational flexibility to
manage flows and adapt to climate change
• Improved connectivity/viability of bull trout populations
• Improved habitat in floodplain, riparian zone, and forested watersheds
• Increased populations of Chinook, coho, steelhead and sockeye
Projected Increases in Fish Populations
PopulaBon Increased Recruitment Spring/Summer Chinook 6,000 – 46,700 Fall Chinook 1,600 – 16,150 Coho 1,650 – 10,700 Steelhead 2,400 – 18,900 Sockeye 170,000 – 380,000 Total 181,650 – 472,450
Water Supply Benefits
• Improve drought year supplies to water-short irrigation districts
• Provide water for growth in municipal and domestic well uses
• Improve security of junior water rights in the Basin
Benefits Quantified in Economic Analysis
• Improved agricultural production in water-short years
• Improved fish populations and public’s willingness-to-pay
• Value of water for municipal growth
• Value of secure supplies for existing municipal/domestic users
Results
Category QuanBfied Benefits
Salmon/Steelhead Recovery $5.0 – 7.4 Billion
Irrigated Agriculture (Drought Years)
$0.8 Billion
Municipal/Domes-c Supplies $0.4 Billion
Total $6.2 to 8.6 Billion

Conclusion
Why IWRM Is Working
• It addresses inter-connected resources
• It solves multiple problems that single-purpose projects can’t
• It provides for adaptation in the face of change and uncertainty
• It draws support from diverse stakeholders and permitting agencies
