《水经注·卷三十三》
这一带土地平旷，有湖泊沼泽，生长菱芡等水生植物，还有卿鱼和大雁，与外江没有两样；这些东西都是进峡之后所看不到的。这地方有很多凶恶的蛮人，不可轻率前去。
其地平旷，有湖泽，中有菱芡鲫雁，不异外江，凡此等物，皆人峡所无，地密恶蛮，不可轻至。
The land here is flat, with lakes and marshes, with aquatic plants like water chestnuts and lotus growing in them. There are also mandarin fish and geese, not unlike the outer river. These things are not seen after entering the gorge. There are many savage barbarians here, so do not go there lightly.
