This information was collected in the North Bay of Raquette Lake during the month of August, 1998 and 2002. You may use this information with your students to introduce and discuss fresh water studies and graph trends of Raquette Lake. You may find it interesting to graph and discuss temperature, light, dissolved oxygen and pH trends in this lake as they correspond to the depth of the lake. Dissolved oxygen and pH were recorded at 5m intervals.
