Water Quality

These charts display the values of water quality indicators for this lake, compared to the range of values seen across all of Maine’s surveyed lakes . Color ramps represent the range of values across all lakes. Yellow diamonds display the mean values for this lake, as averaged across all sampling sites. Click on any diamond to view the data.
Note: Lakes having differences in water quality or data density among different sampling stations may have skewed mean values. In addition, a mean transparency equal to the maximum depth at a sampling station may indicate that the Secchi disk was visible when resting on the lake bottom. In these cases, other indicators (chlorophyll and phosphorus) should be used to evaluate water quality in these cases.

To further explore the statewide distribution of indicator values, click on the bar chart icon . The red lines on the histogram show data from one or more sampling stations for this lake – superimposed on the statewide distribution for the indicator.

The icon indicates that no data are available for this parameter at this lake.
