National Dam Safety Program. John Bollinger Number 1 Dam (MO 31417), Mississippi - St. Francis Basin, Madison County, Missouri. Phase I Inspection Report
John Bollinger No. 1 Dam is an earth dam constructed to impound a lake for irrigation. The normal operating pool outlet or main spillway consists of a 12-in. diameter asbestos-concrete pipe through the center of the dam. The outlet of this pipe is near the toe of the maximum section. A crude trash rack has been constructed around the inlet end. An auxiliary spillway is located at the right abutment. There are no control structures for regulating flows through this auxiliary spillway. Our inspection and evaluation indicate the dam is in generally good condition. No evidence of significant erosion, sliding, cracking or excessive settlement was noted on this dam. No animal burrows were noted. Hydraulic/hydrologic analyses indicate the 1 percent probability-of-occurrence event (100 year flood) will be passed without overtopping the dam. These analyses also indicate any storm greater than 45 percent of the PMF will overtop the embankment.
