Public Education Program
Why have 4 versions of outreach materials talking about water quality?Similar land use and water quality concerns Regional media (print, tv, and radio) covers multiple watersheds MGROW =regional outreach strategySlide24
Moving forward
Volunteer and stakeholder involvementReaching agriculture audienceAdditional data collectionConsistent messageSlide25
