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.
