4. 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

5. Storage
Authorizes $335,000,000 for Federally owned and State-led storage projects determined feasible and produce federal benefits
Federal projects up to 50%
State projects up to 25%
Section 4007

6. Reform of the Title XVI Reclamation Wastewater and Groundwater Study and Facilities Act
New Water Recycling and Reuse Projects
Authorizes additional $50,000,000
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
Section 4009 (c) Pages

7. 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

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

20. Determination by the Fish & Wildlife Service January 6, 2017
Recognized that provisions outlined in the Water Infrastructure Improvements for the Nation Act of 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

21. Extremely high flows in Sacramento spread Delta Smelt far downstream
