North America’s “Waterbelt”

  • Nearly 20% of the world’s surface freshwater

  • About 90% of US surface freshwater

  • Home to 35 million people

    • 25 million US

    • 10 million Canada

  • Major Urban Centers

  • Ecological Treasure

  • “Blue Water” Economy

Great Lakes Water Use

Economy depends on the Lakes:

  • Hydropower

  • Cooling

  • Drinking water

  • Industrial uses

  • Agriculture

  • Tourism, recreation and boating

  • Shipping

  • Fish and wildlife

*Excludes hydroelectric

Great Lakes Governors’ Priorities

Ensure the sustainable use of our water resources while confirming that the States retain authority over water use and diversions of Great Lakes waters.

Council of Great Lakes Governors


Slide6 l.jpg

Great Lakes – St. Lawrence River Basin Sustainable Water Resources Agreement of 2005

  • Good-faith agreement among the Great

    Lakes Governors and Premiers

  • Created Regional Body

  • State and Provincial

    implementation

  • Provincial action

  • Interstate Compact

Council of Great Lakes Governors


Slide7 l.jpg

Great Lakes – St. Lawrence River Basin Water Resources Compact

  • Legally enforceable contract among the

    Great Lakes States

  • Created Compact Council

  • Implementation

    • Ratification by

      State legislatures

      (2006-2008)

    • Congressional consent (2008)

Next Steps Compact

  • Regional water conservation and efficiency objectives established

  • Regional procedures and regulations being developed

  • State and Provincial programs being developed

    • Water conservation and efficiency

    • Water use information

    • Water management and regulation

  • Cumulative impacts to be assessed

Decision Support Needs Compact

  • Improved water use information

  • Consumptive use coefficients

  • Better understanding of groundwater-surface water interaction

    • Gauging

    • Modeling

Council of Great Lakes Governors


Slide10 l.jpg

Decision Support Needs Compact

  • Tools to assess individual and cumulative impacts

    • Improved Basin water supply information

      and water budget

    • Impact assessment tools:

      Physical, biological, chemical

    • Monitoring, predictive and

      forecasting tools

  • Strengthening partnerships

Difficult to Compare Water Use by Sector across state lines due to different methods and data sets


Future needs l.jpg
Future Needs due to different methods and data sets

Consumptive Use vs. Diversions

Improved groundwater information

Increased use of remote sensing to determine water use

More consistency between states on how water use data are collected/available

Support Sec. 9508 of SECURE Water Act (P.L. 111-11) for state/federal partnership in water use data

Improved long-term supply forecasting
