[QUOTE="Matt80, post: 428055, member: 3461"] He's talking about using water in a tub at home that can then be thrown on the garden or lawn or whatever, not going back into the waterways so no absolutely no environment harm whatsoever. As for water turbidity causing harm to the environment, generally speaking this isn't the case. The fish already have to deal with these conditions with every flood, but check out the amount of fish that follow people using dredges overseas. Small fish feed on all the tiny creatures living in the sediment so this is generally beneficial to the system and it also washes gravel which can be good for the spawning of some species. Indeed some rivers in California became less healthy after they banned dredging because the sediments built up(in part this is likely because so much less water flows through many waterways due to irrigation so natural river flows no longer exist).
