Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Can I dredge my pond with a trash pump?

I have no experience in this but i have been wanting to try it also. I talked to one of my bosses and he said to look into a diaphragm (not sure if spelt correctly) pump instead of a trash pump, apparently the larger solids will hurt the impeller in a trash pump. I would be no help in what equipment to use but my idea was to use a trash pump and place it 1-2' above the bottom and use a pressure cleaner to blast the bottom and stir it up and have the trash pump take a higher water to solid ratio. no idea how well it will work but i definitely have considered trying it. If you do try it would love to see a post with how it goes!
