The 2017 dredging season has begun!
We need at least $165,000.00+ in funds to take us into the 2017 season. Please be generous with your contribution
we are half way through this giant undertaking!!
Interesting Facts About the Dredging Process
Most of the bottom of Puslinch Lake contains extremely dense clay.
The barge, when empty, draws 3 feet of water - when fully loaded, it draws ( draft ) 5 feet of water and travels 1.8 km per hour.The container, or hopper on the barge holds five rock trucks full of material ( 175 tons). The rock truck is a six wheel drive, off-road dump truck which weights 60,000 lbs when empty. It holds approximately 30 - 40 tons of material. The rock truck takes approximately 1 hour to empty, depending on the off-loading location in the pit. There is presently in excess of 100 rock truck loads of material drying at this location.
The pit that is presently being used is reaching its maximum capacity, and is up to 8 feet in some sections. We have in excess of 1100 rock truck loads (38,500 tons) of material drying. Removal of material from the pit is one of the biggest challenges presently facing the restoration project.
Dredging on the east side of Big Island will require a new area to dispose of the material, as the barge cannot manoeuver with a full load over the shallow depths in this area.
The average cost to operate effectively per year is approximately $150,000.00
