What happened
The episode as NWS PAH wrote it up.
The Mississippi River was above flood stage at the Thebes gage for most of the month. The flooding was minor to moderate, confined to unprotected bottomlands and adjacent access roads. The first crest of 37.0 feet occurred on the 10th, with a second crest of 33.7 feet on the 28th. Flood stage is 33 feet. Between the two crests, the river was below flood stage from the 14th to the 22nd. Another effect of the high river levels was to raise tributary creeks and rivers above their banks, including the Big Muddy River.
