Why protect the Lake’s watershed?

  It’s our main source of drinking water!

  •  Major industries rely on the Lake’s water for day-to-day operations.                                        
  •  Conservation in the watershed increases the quality of recreational opportunities on the  Lake itself.                                                
  •  Limiting pollutants entering the Lake means less wear and tear on the Water Treatment  Plant…guarding residents against bearing the costs of repairs.​
