Washington's wetlands protect water quality, reduce flooding, provide aquifer recharge for drinking water and other uses, and provide critical habitat for fish and wildlife. We work in partnership to protect, restore, and manage wetlands and their important functions. We pursue this mission by providing technical assistance to local governments and other parties, reviewing development proposals to ensure potential wetland impacts are considered, developing mitigation policies that offset unavoidable impacts to wetlands, and helping organizations obtain funding for wetland conservation projects.

Wetlands overview
