PHCC recently acquired top-of-the range water quality monitoring equipment to aid in the monitoring of the Peel-Yalgorup Ramsar listed wetland system. This equipment can measure salinity, pH and dissolved oxygen and will initially be used to carry out regular assessments of water quality at Lake Clifton and the other wetlands of the “Yalgorup Lakes” system. The salinity probe had to be selected with care as many off-the-shelf probes can’t measure salinity at the levels found in some of these unique lakes. For example, Lake Hayward is many times the saltiness of seawater which is natural for this particular waterbody. This work is all part of a larger program that aims to characterise this system of wetlands in better detail than has been done up until now.
