Lake is a primary drinking water source for the Triangle area. The system monitors
for the presence of cyanobacteria (blue-green algae), which can cause taste-and-odor
problems in water supplies. Some cyanobacteria species also produce toxins that
can negatively impact human health. The real-time monitoring data, along with
the cyanobacteria assemblage data, will serve as an early warning system to help
water quality managers manage water supplies to protect public health in response
