Title: California Water Balance


1
California Water Balance
2
Water Reserved for the Environment
3
Hydroelectric Power Generation
  • Hydropower facilities represent about 25 of
    Californias electrical power generation capacity
  • On average, in-state hydropower provides about
    15 of Californias electricity

4
Water Supply Infrastructure
  • Reflecting the disparity in location of water
    needs and available runoff, extensive system of
    federal, state, and local water projects has been
    constructed to move water to where it is needed

6
Federal Central Valley Project
  • Largest single water project in California
  • Operated by U.S. Bureau of Reclamation
  • 18 federal reservoirs plus 4 state-federal
    reservoirs, 12 MAF total storage capacity
  • Largest generator of electrical power in
    California

7
Sample CVP Facilities
8
The State Water Project
  • Californias 2nd-largest water project
  • Operated by DWR
  • 20 reservoirs, 660 miles of aqueduct, 26 power
    pumping plants
  • 4th-largest generator of electrical power in
    California

9
Sample SWP Facilities
10
Local Agency Water Projects
  • Include wide variety of canals, reservoirs,
    groundwater storage projects
  • Also include water recycling projects and a small
    desalination projects

11
Sample Local Agency Facilities
12
Flood Control Infrastructure
  • Federal, state, and some local agencies have
    constructed large-scale flood control projects
  • Major Central Valley Flood Control Project
    features include dedicated storage in numerous
    reservoirs, and 1,600 miles of project levees

13
Water Management Framework
  • Major federal agencies USBR and USACE (provide
    water supply flood control), USEPA (regulates
    water quality)
  • Major state agencies DWR (provides water supply
    flood control), SWRCB (regulates water quality
    water rights)
  • Local agencies provide water supply, flood
    control, water treatment, wastewater treatment

14
Key DWR Responsibilities
  • Operate State Water Project (provides 3 MAF
    annually)
  • Operate maintain flood control facilities
  • Administer state dam safety program (about 1200
    regulated dams)
  • Plan for Californias future water supply needs

Estimated Future Water Needs
Net changes statewide in average-year water
demand for baseline scenarios by sector, 20002030
17
Key SWRCB Responsibilities
  • Administer water rights permitting program
  • Administer water quality planning program
  • Through Regional Boards, administer water quality
    permitting program to assure conformance with
    water quality plans
