Total Phosphorus (TP), a key measure of the amount of nutrients in the water, was
observed to be at generally their lowest level since sampling began. In contrast,
chlorophyll a, which measures the amount of algae in the lake water, was found to
be at its highest level. According to scientific models, low phosphorus levels
should result in lower levels in Chlorophyll a instead of the opposite relationship
observed in 2006. Since temperature, pH and other variables were normal, the
Steering Committee agreed that this discrepancy was likely caused by a change in
lab testing procedures and not a change in lake water quality.
