Endangered Species Concerns, Working Near Salmon-bearing Streams, Preventing Waterway Sedimentation

  • Critical Areas & Endangered Species: If working in known (or suspected) critical areas or with threatened or endangered fish, insects or mammals nearby, seek  guidance about timing and other actions you need to take. Staff at local resource agencies can ensure you’re following appropriate guidelines and won’t be in jeopardy of inadvertently harming critical species; they will also advise you if you need to contact the Washington Dept. of Fish & Wildlife or the U.S. Fish & Wildlife Service.
  • Contact for support/guidance
  • Preventing sedimentation in waterways: If working directly adjacent to a waterway and engaging in soil-moving or soil-disturbing activities that are sufficiently disruptive to cause migration of sediment into the stream, you need to employ temporary sediment control system, such as silt fences/hay bales.
