Next we needed to consider input from the 7 other lakes which drain into Long Pond.  You can see that Great Pond is the largest influence.  It contributes 77% of  the total water coming into Long Pond (POINT).  The other lakes contribute relatively minor amounts to the Inet.  These I net values were calculated using 2 methods.
Great Pond, Watson, Whittier, and Kidder Ponds where the MDEP had sufficient data on, the input was determined by multiplying the flushing rate by the lake surface area and the mean depth to determine input.  For Round, Beaver, and McIntire Ponds where less data was available, we took GIS information on the respective watershed areas and tabulated precipitation, runoff, and evaporation.
