Water Level Management

What are the anticipated impacts to water level management and groundwater management in the region?

  • IGLD (2020) will be the new reference level used for regulating outflow in the lakes.
  • IGLD (2020) should be used for future surface water modeling and management. Consequently, adjoining river management plans should be updated.
  • Current models and decision-making tools, such as the NOAA Lake Level Viewer, will need to be updated.
  • Adjusted water level heights may affect dam and lock operations.
