Waterfowl are natural part of the lake ecosystem. They eat lake plants and
excrete nutrients that support new plant growth. Feeding waterfowl increases
waterfowl populations, which encourages the lake plant growth though added
nutrients. Waterfowl excretions may contribute to the cycle of organisms
which causes swimmer's itch.
ONE DUCK EXCRETES ONE
POUND OF PHOSHORUS PER YEAR. ONE POUND OF PHOSHORUS IS ENOUGH TO GROW 750
POUNDS OF ALGAE IN THE LAKE. HIGH PHOSHORUS LEVELS INCREASE WEED AND ALGAE
GROWTH IN SPRING LAKE.
artificial feeding of waterfowl is not beneficial for the waterfowl, or for the
people who enjoy Spring Lake.
Signs like this will be posted around Spring Lake by the SL - LB to help
remind people that feeding the waterfowl may lead to an increase of algae growth
in the lake.
