大壩決堤,水庫排空 - 恢復白鮭魚河

這是一段由攝影師安迪·梅瑟拍攝的令人驚歎的影片,記錄了上個月康迪特大壩被炸藥炸開的情景。這座125英尺高的大壩於1913年建在華盛頓州白鮭魚河上,在兩個多小時內排空了水庫中的水。

近一百年來,白鮭魚河首次將自由流動,恢復河流成為當地魚類物種的自然棲息地。來自《西雅圖時報》

大壩位於河流與哥倫比亞河交匯處三英里處,拆除大壩預計將為硬頭鱒重新開放約 33 英里的棲息地,為奇努克鮭魚重新開放約 14 英里的棲息地,具體取決於不同種群的魚類如何應對河流中的天然瀑布。

令人驚訝的是,過去一個世紀積累了如此多的淤泥,這隨著時間的推移降低了發電能力,並加速了大壩的拆除。擁有康迪特大壩的電力公司發現,拆除大壩比使其達到現代環境標準更便宜。

這段影片再次提醒我們,所有形式的能源都有權衡——即使是像水力發電這樣相對清潔的能源也是如此。
