Historic High WaterPosted on April 27th, 2011
Recent record rainfall has swollen area lakes and rivers and necessitated the opening of all flood gates on Table Rock Dam. Highway 165 over the dam is closed to traffic at this time due to a mudslidde on the downstream side of the earthen embankment.
This from the US Army Corps of Engineers website:
“Three geotechnical engineers from the Army Corps of Engineers Little Rock District inspected Table Rock Dam and agree the mudslides are surface “skin” slides that pose no threat to the integrity of the dam. The engineers arrived on site and conducted the inspection. There are actually two mudslides, and engineers think these two sections may connect together into one area, especially if the rains continue. To the eye, the slides appear to run all the way down the face of the earthen portion of the dam, but this is mainly topsoil that has simply slid across the surface, thereby making the situation appear much worse. The inner core of the dam is sound and undamaged. The Corps, the Missouri Department of Transportation and the Missouri State Highway Patrol closed Highway 165 across Table Rock Dam earlier today until further notice in the interest of motorist safety because the slides begin near the highway guardrail.Corps employees and local emergency management officials are hearing numerous rumors circulating about the slides. Information can be obtained from the local Corps office or at the official Little Rock District Website at www.swl.usace.army.mil. The geotechnical team believes there is no imminent threat to the safety of the dam and that Table Rock Lake can be managed in a normal fashion to help reduce flood damage during this storm event. No change in the Corps’ water management plan is warranted.”
Tours of the dam will be suspended until further notice. The Dewey Short Visitors Center remains open to the public.
