LEA Water Survey of Keoka

July 26, 2019

Under the umbrella of the Maine Lake Science Center, LEA has begun acquiring new information on the chemical, biological and physical processes that occur within lake systems using multi-parameter monitoring probes called Sondes. These instruments acquire geo-referenced data simultaneously on turbidity, pH, oxygen, temperature and algal populations. One initiative is to spatially map the surface water quality of lake systems.  This project uses a boat-mounted, flow-through system to generate rapid, high intensity measurements of surface conditions all over a lake.

Interpolation of these survey data produce snapshots in time of whole lake status. This type of high-resolution, spatial assessment has been done by a few other researchers in the country, but the methodology is still fairly new.
