Falls
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
to blooms.
