Abstract: Fifteen stream sites where Orconectes (Rhoadesius) sloanii (Bundy) and O. (Procericambarus) rusticus (Girard) were usually found together in 1975-1977 were revisited in 1989. In nine of the localities O. sloanii was absent and in three others the ratio of O. sloanii to O. rusticus had decreased. At the remaining three sites the ratio of O. sloanii to O. rusticus increased at one and O. rusticus was no longer found at the other two.
