Originally, outside of the dikes there were 17 acres of protected aboriginal land. In 1976 this had been eradicated by flowing soil and rocks carried from upstream. Although the county government agreed to compensate the residents NT $ 143,800 per acre, the aborigines no longer had enough to invest in recovering the land, since "after another year it would just be washed out again!"
在堤防外原有七甲開墾為水田的山地保留地，六十五年也被上游滾滾而下的土石流（含砂帶石的水流）淹沒，縣政府雖一甲地賠償六萬元，但當地居民已無力投資整地，「隔年還是會再淹掉！」
