Association of Ground Water Agencies

• The Association of Ground Water Agencies, or
  AGWA, was initially formed in 1994.
• Mission statement The mission of the Association
  of Ground Water Agencies is to provide a unified
  voice for groundwater management agencies, to
  coordinate efforts and exchange information to
  enhance the effective management of groundwater
  resources in California.
• Specifically, AGWA's purpose is to create a forum
  for the discussion of groundwater issues of
  interest to those entities which, either by court
  judgment or statute, are responsible for
  management of groundwater basin resources, and to
  take action where appropriate in connection with
  such issues.
• AGWA's primary objectives are to
• promote more effective means of enhancing
  management of groundwater basins
• promote the reliability of existing groundwater
  supplies and the increase of basin yields
• promote the protection and enhancement of
