  • California Department of Water Resources
  • City of Davis
  • City of Winters
  • City of Woodland
  • Dunnigan Water District
  • Reclamation District 108

We are actively seeking to expand our monitoring network in data gap areas. If you are interested in joining the voluntary monitoring program, please contact us!
