Bank deposit (4)

Ross

I believe the answer is:

silt

'bank deposit' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for silt that I've seen before include "Mud deposit in a river" , "Material deposited by a river" , "Mud deposits in a river" , "Slimy mud" , "Sediment deposited in channel or harbour" .)

I've seen this clue in the Newsday and the LA Times.
