Marlene Schoeneck's Environmental
Biology class partnered with the Lake
Association members Paul Anderson, Steve
DeSutter, and Gene Rose to collect data
on the lake on September 27, 2018.
focus was to determine the cause of
increased aquatic vegetation in various
areas of the lake. Data collected
included plant types, water clarity,
bottom substrate, nitrates, phosphates,
and shoreline plant cover. All these
were evaluated as possible contributors
to an increased plant growth.
PHOSPHATE - levels are steady
NUTRIENT LOAD - does not appear
to have changed significantly.
SPECIES - does not appear to
have changed significantly.
CLARITY - has increased in
recent years due to filtering by zebra
GROWTH - was greater in areas
with "mucky" bottom substrate. Appears
to be more prevalent in areas with
organic soil runoff. Shorelines
that are primarily sand had less
vegetation. There also seems to be a
relationship with bulrushes holding
organic matter in shorelines.
