We examine the morphology and dynamics features of the river channels within the basin of the lower reaches of the Amur river on spawning grounds. We report evidence that the spawning grounds tend to occur at definite elements of the river channel as well as data on particle-size composition of alluvial deposits in autumn chum salmon (keta) spawning stretches. Factors having a negative influence on the preservation of spawning grounds have been identified.
