Today, the “Peace Dam” — begun in 1987, abandoned halfway through as a misguided cold war scheme, then revived and completed in 2005 — stands here, a 410-foot-high, 1,970-foot-wide rock and concrete hulk. There is no reservoir; the dam’s only function is to contain a possible deluge, by accident or design, from the Imnam Dam in the North, 22 miles up the northern tributary of the Han River. —NYT
