Read this note before interpreting the next slide:
The chlorophyll a predictions for each water supply were developed using the Southeastern Lakes model (Reckhow, 1990) except for Falls Lake for which a calibrated BATHTUB model was available.
Southeastern Lakes model predictions reflect whole lake growing season averages (May - Oct); individual observations above the predicted averages and the guideline range are likely.
The graphs for Falls Lake reflect predictions near the water supply intake and for the entire lake. Because of its size, chlorophyll a concentrations near the dam tend to be much lower than concentrations found in the upper portions of the lake.
The project consulting team recommends using the graphs only as a relative indicator of the magnitude of likely change in the growing season average chlorophyll a for each lake, assuming that management does not change from existing policies and procedures.
