Calculating the Net Input
�Inet = (runoff * watershed area) + (precipitation * lake area) – (evaporation * lake area)
�Inet = (0.622 * 2.316 x 107) + (1.057 * 5.160 x 106) – (0.560 * 5.160 x 106)
�Inet Long Pond North = 1.697 x 107 m3/year
This is a display of the net water input to Long Pond, from adding the amount of water running off the land, to the water directly raining on the lake, and then subtracting the evaporation off of the lake (POINT).  The second line shows the numbers for coefficients and areas from the last slide substituted in (POINT).  Our final  Inet value turned out to be about 17 million cubic meters of water per year (POINT).
