Study Shows That Bonfires
Can Cause Lake Problems

If you enjoy a bonfire near the shoreline, remember to grab a shovel after the fire is out and dump the ashes inland to prevent the phosphorous in the ashes from seeping into the lake, according to University of Idaho researchers. or better yet, consider moving your fire pit inland, far away from the shore.

An average bonfire containing 22 pounds of firewood produces enough phosphorous to raise the phosphorous level 1 part per billion in 350,000 gallons of lake water - a significant amount.

Phosphorous stimulates an over growth of algae and aquatic plants, which decompose after they die and in several generations - cause a lake to fill up with muck prematurely and become a marsh.
