224-625: The dam's creation. The dam is located near the main part of Ena City, and residents also opposed it on grounds that it would've disrupted the area's excellent transportation; negotiations stalled. In response, the dam was designated as subject to the Act on Special Measures for Up-stream Area Development, enacted in 1973.
