Phosphorus has been shown to contribute to the spread of aquatic weeds and the growth of algae, robbing water of oxygen that fish need to survive and limiting the recreational use of lakes and ponds.

Phosphorus is brought into the Upper Saranac Lake basin each year by lawn fertilizers and through wastewater treatment systems. Fertilizers applied to lawns or gardens wash into the lake with every rain storm while phosphorus from detergents, such as dish washing soaps, leach through septic systems and into our water source.

Dense Eurasian water milfoil and increased algae growth appear with regularity adjacent to fertilized lawns, gardens and waste water systems.

Here is what you can do:

  • Stop using phosphorus products; at a minimum switch to phosphorus-free lawn fertilizers.
  • Reduce lawn areas in favor of trees or natural ground cover.
  • Establish a natural plant buffer area along your lakefront. Low growing shrubs or natural, unfertilized rock gardens are good.
  • Use phosphorus-free dish washing detergents.
  • Eliminate storm water runoff towards the lake from your home, driveway, etc.

You’ll be helping to preserve the lake for our children and their children.
