Onterra is currently working on over 35 systems in 10 counties throughout Wisconsin. Our projects include numerous comprehensive management plans, two town-wide lake management plans, and sixteen multi-year aquatic plant studies guiding and documenting third-party herbicide applications. Each project includes grant writing and management at no charge and important opportunities for stakeholder participation and education.
