The 2017 Dredging Season Is Over!
An average round trip takes 1 1/2 -1 3/4 hours in travel, 30 minutes to load, and 1 hour to off load. Total time per load is approximately 3 - 3 1/2 hours per load.
Close to 9000 tons has been removed this year. Hoping to hit the 20,000 ton goal, plus tonnage from future private dredging.
The dewatering pit is filling up quickly, anticipate it to be completely full at year end.
Currently just over the half way point for the PLCA dredge budget
Dredging is going well this year. As of today, approximately 6,000 tons of material has been removed, with a target of approximately 20,000 tons for the year.
The dredging location has changed somewhat due to lack of solid material in the central area. Our goal this year is to dig on the eastern side of the lake in the area that borders the O'Krafka's residence ( Eagle Point ) and the Chute's residence ( North/East shore ). During the days of high wind we are digging an area east of the big island, using the island as a wind break to prevent the barge & equipment from being blown into the eastern shores. Wind and lightning storms have certainly been a challenge for the team this year.
Baring any unforeseen problems, private dredging will start mid September through to mid November. The average cost, depending on how many loads are being removed, will be $1750.00 plus HST. Financial commitments will determine who gets dredged first and in what order. The PLCA's overall dredge plan takes precedence over private dredging. All personal requests should be accompanied by strong support of the Puslinch Lake Conservation Association. To make arrangements for private dredging, please contact Dave Taliano at 519-651-1488.
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
