堰の高さはそれほど無いが，西側の広大な平原を見ると，いかに効率的にここが機能しているかを感じる。ここに来るまでに通ってきた低い丘の風景を思い起こす。素人目にはどこに何を作ればよいか，全く分からなかった。綿密な測量と計画があったのだろう。＠烏山頭水庫 Although the height of the weir is not so much, but when you look at the vast plain spreading to the west, I felt how efficiently this reservoir is. I remembered the scenery of the low hills through before I came here. I didn't know exactly where to make anything for supply, with the amateur eye...I guess there was a thorough survey and plan. @Wushantou Reservoir
