Urban Water Institute Water Infrastructure Improvements for the Nation (WIIN) Roger K. Patterson Assistant General Manager The Metropolitan Water District of Southern California

Water Infrastructure Improvements for the Nation Act (WIIN - S. 612) Enacted December 16, 2016 To provide for improvements to the rivers and harbors of the United States, to provide for the conservation and development of water and related resources, and for other purposes Includes Water Resources Development Act (WRDA) of 2016

WIIN Act (S. 612) Title I Water Resources Development Act 2016 Water resource infrastructure Title II Water and Waste Act 2016 Safe Drinking Water Act and Solid Waste Disposal Act (Coal Combustion) Economically distressed communities and the prevention of lead contamination and other public health concerns Title III Natural Resources California water supplies Tribal water rights settlements Title IV Other Matters Miscellaneous provisions including amendments to the WIFIA provisions

Key Issues for California Title III – Subtitle J: California Water Authorizes USBR to invest in storage projects for public benefits Title XVI Wastewater Reuse Reform CVP/SWP operational provisions Improved Science Increase San Joaquin River inflow and transfer/exchange capability

Storage Authorizes $335, 000 for Federally owned and State-led storage projects determined feasible and produce federal benefits Federal projects up to 50% State projects up to 25%

Reform of the Title XVI Reclamation Wastewater and Groundwater Study and Facilities Act New Water Recycling and Reuse Projects Authorizes additional $50, 000 Municipal, industrial, domestic or agriculture wastewater or impaired ground or surface water Competitive grant program Areas experiencing drought within 4 years of funding Provide more reliable water supply for states and local governments Increase water management flexibility and reduce impacts on environmental resources from projects operated by Federal and State Agencies

CVP/SWP Operational Provisions Enhances supply opportunities Capture peak flows during storm-related events when risks to fish appear small Manage flow patterns toward export pumps (OMR) Expand monitoring

San Joaquin River Enhance flows down the San Joaquin River through voluntary Sales Transfers Exchanges Allow to be pumped at 1: 1 ratio

Delta Operations in 2016 -17

Flows in the Delta Natural flow direction N Reverse flows occur when direct flow to pumps is less than total pumping Sacramento River Flow OMR reverse (negative) flows Exports Delta Map Banks and Jones PP San Joaquin River Flow Direct flow to pumps

Delta Smelt Life-Cycle and Protections FALL WINTER SUMMER SPRING

Delta Smelt Life-Cycle and Protections WINTER RPA 1 Action 1: Dec-Jan • Protect adult migrating smelt • OMR > - 2, 000 cfs SUMMER FALL RPA 1 Action 2: Jan-Mar Triggers • Protect adult smelt prior to spawning • OMR Range: - 1, 250 to -5, 000 cfs Action 1: Turbidity or Salvage Action 2: Following Action 1 SPRING WINTER

Flows in the Delta Natural flow direction N OMR reverse (negative) flows Exports Delta Map Banks and Jones PP Direct flow to pumps

Flows in the Delta – Elevated Risk Scenario Elevated risk of Delta Smelt entrainment when Sacramento flows increase, but San Joaquin flows do not. Turbidity could move into South Delta, attracting Delta Smelt N OMR reverse (negative) flows Exports Delta Map Banks and Jones PP Direct flow to pumps

Limited Smelt Distribution in South Delta 227 Undetermined (100%) Monitoring suggests Delta Smelt distribution remains far from export facilities Males Females Exports Banks and Jones PP

Determination by the Fish & Wildlife Service January 6, 2017 Recognized that provisions outlined in the Water Infrastructure Improvements for the Nation Act of 2016 must be taken into account Dec 16 Preemptive measure resulted in OMR of -6, 000 Planned operations appeared to avoid turbidity bridges in OMR with less water supply impact than would have occurred under Action 1 Continue to monitor conditions and seek recommendations from Smelt Working Group Recognized collaborative efforts of agencies to reduce risk to delta smelt

Favorable Conditions Occurred in Jan 2017 Extremely high flows in Sacramento spread Delta Smelt far downstream N High San Joaquin flows allow higher pumping while limiting negative OMR reverse (negative) flows Exports Delta Map Banks and Jones PP Direct flow to pumps
