I posted in another thread discussing muck removal options but thought I would give this a dedicated thread. One suggested DIY solution to remove organic muck from an old pond is to build something akin to a gold dredge with a trash pump and a venturi dredge nozzle. Does anyone have real world experience doing this? Did it work well? Any tips or lessons you learned along the way?

My thought is to build a platform to paddle/pole around the 1.75 acre pond that can be anchored in position. A 3" trash pump would ride on the platform. A pole would be attached to the nozzle (so the user can stand on the platform and suction the bottom). The mucky water would be sent to the shore where some form of dewatering would occur (dewatering bags, silt screens, etc.). Here are some visual examples:

Three homeowners share our pond and there is a guy up the road who is facing the same problem with his pond. A dredge company quoted the guy up the road $7,000 to clean half of his 0.75 acre pond. That is not affordable for any of us.

I'm looking to pitch the idea of building a platform and dredge to the other 3 parties with the idea of splitting the build cost 4 ways. Depending how nice a pump and hose we buy, I'm guessing this would be a $2000-2500 venture divided 4 ways. Then it is just a matter of chipping in time and we are not in a rush. The bigger concern is to not stir up the bottom and turn the pond toxic to the fish. Before I get serious about pricing out equipment and talking to everyone, I want to make sure this method is truly viable.

I would appreciate hearing anyone's experiences and thoughts.

Thanks!
