Water Drawdown
�Removal of nutrient-rich water
�Modification of culvert and dam
| Assume that input to refill
lake will be less nutrient-rich so as to dilute remaining lake water |
|
| Culvert at south end of
Togus Pond under Route 105 only allows several inches of drainage, need 2.5 -
5.5 feet of drainage |
|
| Dam at south end of Lower
Togus Pond must be modified to drawdown Lower Togus Pond in order to allow
waterto drain from Togus Pond through culvert. |
|
| This technique is used
primarily for reservoirs and small ponds, like Webber Pond has for a few
years now |
|
| Cost depends on dam and
culvert modification |
