UPDATE: RAPID CITY, S.D. (KEVN/KOTA TV) - After evaluating the situation, authorities reopened Highway 14, according to a Rapid City/Pennington County Emergency Management social media post.
The post stated that officials on scene believe the normal drainage, culverts and floodplain can handle the breach in the Quinn Dam, even if it grows. Furthermore, no structures are in danger.
Still, the area will continue to be monitored in case conditions change.
Highway 14 from Wall to Philip is closed due to the breach of the Quinn Dam about a north of the highway. The closure between Interstate 90 exit 112 at Wall to Highway 73 at Philip.
According to the state Department of Transportation, no water is on the road now but that could change “very quickly should the dam fully breach so the road has been closed as a precaution,” a DOT release stated.
The Quinn Dam was reportedly breached earlier Tuesday morning. The South Dakota Highway Patrol is on the scene monitoring the situation. People living in the area, including a rancher, have been notified of the danger.
The detour route is Highway 73 and I 90 for both east and westbound traffic on Highway 14.
With fears that a dam will collapse, the National Weather Service in Rapid City has issued a flash flood warning for several counties, now through 3:30 p.m.
Tuesday morning, emergency management reported a breach in the Quinn Dam. Flash flooding is expected to begin shortly, especially if the dam fails.
• Southwestern Haakon County
• Northwestern Jackson County
• East central Pennington County
Some locations that will experience flooding include Quinn and Cottonwood, and locations along Cottonwood Creek.
People in these areas need to be aware and if necessary, move to higher ground.
