big lake
Big Lake provides important wildlife habitat, and offers many recreational opportunities, including: swimming, fishing, boating, and shoreline-related activities. The lake has a Washington Department of Fish and Wildlife boat ramp and is heavily used by both lake residents and the public for recreation. Beneficial uses of the lake have been severely impacted from dense, prolific growth of invasive aquatic plants, including Brazilian elodea (Egeria densa), Eurasian watermilfoil (Myriophyllum spicatum), and fragrant water lily (Nymphaea odorata).

To combat noxious aquatic weeds, the lakeside residents at Big Lake began a program of mechanical harvesting to remove the plants in the early 1990's; however, this endeavor was unsuccessful due to the rapid growth rate of the plants. In 1997, the lake community voted to form a Lake Management District (LMD) for a 5-year period; upon expiration, the LMD was reformed for another 10-year period.

The stated goals of the LMD, in accordance with the Integrated Aquatic Vegetation Management Plan, are to:

  • Aggressively remove noxious weeds such as Brazilian elodea, Eurasian watermilfoil (if found), fragrant water lily, and yellow flag iris from the lake.
  • Promote better watershed management.
  • Reduce algae blooms.
  • Eliminate the need to mechanically harvest weeds.
  • Swim, water ski, and boat without touching the weeds.
