Benefits of Headwater Wetland Construction

  • Water Quality Functions
  • Filter pollutants, thus decreasing nutrients & removing/reducing sediment loads from agriculture within the contributing watershed
  • Water Quantity/Hydrologic Functions
  • Provide storage to reduce peak flows & erosion
  • Habitat/Ecological Functions
  • Increase habitat for raptors, waterfowl, wetland associated birds, & aquatic invertebrates
  • Increase native plant richness
  • Increase corridor connectivity to the Nooksack River, Slater Slough, Smugglers Slough, Lummi River, & Lummi Bay
