This species is relatively restricted range (etimated area of occupancy (AOO) < 2,000 km²) and is only known from six river basins and two lakes, which are treated as separate locations on the basis of the likely threats. Formerly the species was extremely common but it has now disappeared from two rivers and has become rare in many others mostly as result of interaction with the introduced, congeneric species, Padogobius bonelli. Other causes of decline are water extraction and rising water temperatures due to lower water levels, pollution and predation by alien species.
