ISSUES AND OTHER INFORMATION

  • Sonoma Water (formerly Sonoma County Water Agency) is the Non-Federal Sponsor (NFS).
  • A Biological Opinion (BO), issued by the National Marine Fisheries Service, mandates that SCWA and USACE perform various Reasonable and Prudent Measures to save threatened and endangered salmonid species. Implementation of this ecosystem restoration project will help comply with these BO requirements.
  • Real estate negotiations between landowners and the non-Federal Sponsors are projected to delay the Phase III portion of Dry Creek by approximately two years
