Not all mussels live in flowing water, I.E. the Pond Mussel and can sometimes prefer the sand muck to a rockier substrate...many are/were found in lakes. The Great Lakes at one time had a nice fauna of mussels. There are several species with the name washboard in them..they are rigded laterally, like a washboard. There is published data about the amount of volume zebra and quagga mussels filter especially up here in the great lakes...quagga is a much bigger problem than the zebra now here. Asian clams though dont seem to be too much of a competition problem because they do like sandy substrates as opposed to most native mussels like a rocky gravely substrate.
