WQ: Chlorophyll_a in Sheepscot Lakes 1979-2002 |
|
Caption: This chart shows mean chlorophyll_a levels in eight Sheepscot lakes for the period of 1979-2002. Mean chlorophyll_a levels range from 2.8 to 13 ppb in Sheepscot lakes and were highest in Travel Pond. The error bars show the standard error of measurements over the period. Chlorophyll_a concentrations are an indicator of the trophic state of a lake where, higher concentrations indicate a more trophic state. These data were collected as discrete samples through the Maine Volunteer Lake Monitoring Program and in some cases only one sample was collected per year and sampling often happened between July and September. See individual sub-basin topics for the annual trends in chlorophyll_a levels. See Info Links for more information.
