Following. I've been loosely researching a gold dredge setup to clean muck out of my pond. I'm considering the purchase of a reusable dewatering bag and a gold dredge nozzle, then rent a 3" trash/semi-trash pump to see how it works. The gold dredge arrangement does not have the muck/silt/etc. going through the pump housing.
A more expensive option I found along the DIY route is this:
