During winter 1986, surface salinity was 54 ppt and three zooplankton species (D. bispinosus, O curvata and an undescribed cydippid ctenophore) had established populations in the lake. In 1986/87, high tides caused nearby Taynaya Bay to flood into the lake, and three further species (the calanoid, Paralabidocera antarctica, and two harpacticoids, Harpacticus furcatus and Idomene sp.) were found in the lake. It appears that periodic flooding after 1978 caused a salinity decrease in the lake from 66 to 54 ppt, and this enabled some invertebrate species to maintain year-round populations, whereas others require marine incursions to re-establish summer only populations.
