It is estimated that over four feet of muck/organic material (including bird droppings and debris that has blown in from Fayette Street) has accumulated since the Pond was last cleaned-out in the mid 1980s...
The Village has consulted with engineers and biologists, and it was determined if left alone, the algae would become prolific causing the water quality to decline and the toxicity to aquatic life to increase.
Also, leaving the accumulated muck/organic material untouched could cause the water temperature to continue to rise making the Swan Pond no longer able to sustain a viable ecological population.
Under my direction, the Swan Pond Committee also explored hydraulic dredging. But the logistics and costs made it prohibitive. Hydraulic dredging estimates came in $140,000.00 higher than conventional dredging.
As work progresses to clean out the bottom of the Pond, a layer of organic latex will be applied to the exposed areas to minimize the impact of odors.
The dredged "spoils" are being transported to the Kinsella Quarry.
As we undertake this phased, pay as we go, approach to making improvements to the Swan Pond, I am ever mindful that we are stewards of not only this beautiful and beloved landmark in the heart of our community, but the great Village of Manlius as well... The oldest and best Village in Onondaga County that happens to be on the eve of its Bicentennial Celebration.
This work on the Swan Pond will truly ensure a lasting legacy for generations to come!
Mark-Paul Serafin is the mayor of Manlius.
