Millport Reservoir Algae 2003
Samples collected during the MSc Biology of Water Resource Management Field course, May 2003
|
Millport formerly
had 2 reservoirs to supply its water: we sampled the lower one (left in the
photograph).
Samples of the plankton were taken with a net, also of the periphyton by brushing
a stone,
and picked by finger from the spillway (see next image).
There was a heavy growth of periphytic algae in the spillway.
The species of algae found can be a useful indicator of water quality.
