coffer dam stretches across the Oma river in Ethipoia. The coffer dam is a smaller dam that blocks off the flow of the river during construction of the main dam, the Gibe III dam will eventually reach 778 feet high, spanning the picured canyon, and provide 1,870 megawatts of electricity to the surrounding region.

If there were an award for most-traveled Walla Wallan, Ernie Schrader would likely win it. Schrader, who competes in endurance horse-racing in his spare time, has been to more than 35 countries while working on more than 100 different dams across the globe as an engineer. Most recently, Schrader returned from an April visit to the Gibe III Dam on the Omo River in Ethiopia, for which he is a consulting engineer and principal designer. Schrader also spoke at the Africa 2013 conference in the Ethiopian capital, Addis Abbaba, a conference on hydropower and water storage.
