Lake Disappear
An intermittent lake in the limestone country near Raglan on New Zealand's North Island. After prolonged heavy rain the Pakihi Stream backs up behind its sinkhole and floods a normally dry valley floor up to about 15 m deep; then the water drains away underground again. It is the largest solution lake and polje known in the country.
