| The primary purpose of a
water budget calculation is to determine the flushing rate of a lake. This
is a measure of how often the total volume of water in a lake is replaced
per year. |
|
| This is valuable
information in projecting the future of Long Pond North with changing land
uses because the length of water retention time is a factor in the lake
vulnerability. Low flushing
rates do not change water quality, but they do make a lake more susceptible
to accumulations of nutrients and pollutants. Furthermore, Long Pond South receives water from the North
Basin. Any negative changes in
Long Pond North will adversely impact the water quality of the south basin
in relation to drainage rate. |
