Watershed
The ANC watershed or drainage area, covers approximately 5,000 acres, and includes five sub-watersheds. Each of these sub watersheds drains to a separate discharge point in Lake Spenard, Lake Hood, Knik Arm or Turnagain Arm.
In 1992, the ANC Storm Water Pollution Prevention Program was formed to protect these resources through the implementation of procedures and practices that minimize the impact of storm water runoff that is generated from airport facilities and activities.
