Winter Ice Sampling
Photos from winter sampling on Fresh Pond in March, 2014. CWD and CFD staff carefully trekked out on the ice, which ranged from 12 - 14 inches thick. After drilling holes CWD staff measured temperature and dissolved oxygen levels vertically throughout Fresh Pond to check the ecological health of the Reservoir.
