DALLAS (AP) — Rising water levels will likely delay repairs to a 160-foot-long landslide along the Lewisville Lake dam, a possible threat to the hundreds of thousands of North Texans who live downstream.
The U.S. Army Corps of Engineers said 16 inches of rain from severe thunderstorms over the Thanksgiving and Christmas holidays have caused problems with tarps they put over the landslide.
The corps, which manages the lake for the federal government, had planned to begin repairs on the landslide Monday. Lewisville Lake manager Rob Jordan said that's now highly unlikely.
More erosion of the dam, rated by the corps as the eighth most hazardous in the country, is possible.
The massive landslide appeared in late June after record rainfall hit North Texas in May, Jordan said. The landslide is adjacent to another major slide that occurred in 1995, suggesting instability within the embankment.
Back then, large rocks covering the embankment and a section of the asphalt road along the crest of the dam came tumbling down.
