On Sunday, October 16th, AER visited Bantam Lake to conduct monthly water quality monitoring and biweekly cyanobacteria monitoring as part of the ongoing lake man-agement program. Water column profile data, total depth measurements, and Secchi transparency data were collected from the North Bay Site (N 41.71087° W -73.21155°), the Center Lake Site (N 41.70056° W -73.22102°), a site west of Folly Point (N 41.70773 W -73.22638), and at a site in the South Bay region of the lake (N 41.69015 W -73.22728).
Water samples were collected at the North Bay Site and Center Lake Site for algal analyses. These samples included whole water samples, which were integration of the top three meters of the water column, and a plankton net tow sample. These were pre-pared and analyzed as described in our memo of April 15th.
General Conditions
Air temperatures increased from the mid-40s °F to the upper 50s °F during our time on
the lake (https://www.wunderground.com/dashboard/pws/KCTLITCH9/graph/2022-
10-16/2022-10-16/daily). Calm wind conditions changed to light winds by 10:30am. A
light cyanobacteria surface scum was observed across much of the lake (Fig. 1).
