Water velocity and depth preferences of spawning Atlantic salmon (Salmo salar) in four rivers in Maine were measured during October in 1975‐1977. Female Atlantic salmon constructed redds in water with a mean depth of 38 ± 0.8 cm. Mean water velocity measured 12 cm above the substrate was 53 ± 1.3 cm/sec. Management implications of water depth and velocity requirements of spawning salmonids are discussed.
