William Kumanichi updates us on Tateno Dam, which, at its current height of 40 meters (its final height will be 87 meters), is said to resemble a fortress. About half done now, it is scheduled to be completed in April 2023.
What I didn’t know is that the dam is to a “running water type.” This means that the three apertures, each 5m², have no covers - they remain open - such that the reservoir does not store water under normal conditions. Should heavy downpours result in a flow exceeding the rate of the apertures, the dam will hold the water and release it gradually, thus preventing flooding downstream. Neat, eh?
