Temperature Dissolved Oxygen Concentration Ph Chlorophyll-a The RUSS buoy uses a fluorometer to estimate Chlorophyll-a concentrations. Chlorophyll-a is a pigment found in algae and is used as a measure of the algae in the water column. The goal established for the Lake Sammamish Management Plan set the mean summer chlorophyll-a at less than 2.8 mg/L. Look up today's Water Column data for South Lake Washington.
