Is the salinity of Lake Clifton (Yalgorup National Park) increasing?

Salinity of Lake Clifton, within Yalgorup National Park, Western Australia, varies annually in step with the annual change in water level. During the 1980s, salinity in the northernmost, permanent basin of the lake was hyposaline, varying between 8-32 g L-1. In the late 1990s, however, recorded salinity values varied between 25-49 g L-1. This brief communication serves to initiate discussion on whether salinity in the lake is increasing. If the salinity is increasing, then the scientific values of this lake are threatened.
