A lake inland?

Menindee is about a hour drive south form Broken Hill and i have no idea where such a amount of water can come from but its there. A small town and very friendly people. Only wish that we had a 4WD as there was plenty more places to see. Only one road in and out of the town and it started to pour so we bolted as we didnt want to get rained in. Returned back to the Caravan Park and settled in for the night, it was cold and wet so what better than to snuggle up in the back of the Hippie Camper and watch a few movies :-)
