Water Quality Monitoring

Caspian Lake remains good to excellent for water clarity with a best reading of 12.5m (41ft) in mid July. Average levels for Chlorophyll-a and some increase trending in Total Phosphorus still exist. Our Lay Monitors collect 6 samples (2 in each of the months of June, July, and August) and the VT-DEC (Dept of Environmental Conservation) compiles results. Because of the increasing trend in Total Phosphorus, we are testing 5 Tributaries around the west, north, and east sides of Caspian Lake to see if we can determine any sources of higher concentrations, such as agriculture, road runoff, or areas of erosion. This data will assist in developing plans to reduce both Total and Dissolved Phosphorus from these sources.
