The sanctuary is unique having both fresh water lakes, salt and freshwater marshlands. It is spread over an area of 6.05 km2. Before Indian independence, a check dam was built for storing the waters of river Ruparel just before it entered the sea. Over the years with fresh water of the rain and river on one side and salt water of the sea on the other side, a unique area was formed here. On the other side of the
