High waters prompted the closing of the Chain O' Lakes and Fox River on July 14 so that boat wakes wouldn't rush over sandbag walls protecting homes along the shore. After two weeks of rain that in some areas was seven times the normal amount for that period, and the river's record crest at 13.1 feet Sunday in Algonquin, the waters are finally receding. By Thursday morning, the river had dropped into moderate flood stage at Algonquin, and with dry weather forecast, it was expected to continue its descent and reach minor flood stage by Monday.
