The Fox River at the Algonquin Tailwater, the area downstream from the dam, is expected to remain near flood stage at
9½ feet for the next three days, according to the National Weather Service.
The Fox River at the McHenry dam was approaching flood stage at less than 4 feet as of Wednesday afternoon, according to the service.
Storms have been sweeping McHenry County over the past week, and the county remains under a flood warning and hazardous weather outlook. Scattered thunderstorms, some of which could be severe, are expected to continue through the rest of the week, according to the service.
With more rain expected overnight, more than an inch could accumulate by Thursday morning in some areas.
The wet weather likely is tied to a tropical storm making its way toward the Mississippi coast. Potentially heavy rain is forecast through Monday as the remnants of Tropical Storm Gordon head north, according to the service.
The Fox Waterway Agency has advised that Fox River zones A through C are under no-wake restrictions because of weather conditions. Inflows to the Chain O’ Lakes also appeared to be cresting as of Wednesday afternoon, according to a release sent Wednesday from the Illinois Department of Natural Resources.
McHenry Township Highway Commissioner James Condon said road workers are prepared to fight floods, but as of 3 p.m. Wednesday, area flooding did not pose a major threat to area residents.

Sandbags are available to residents outside McHenry Township Hall, 3703 N. Richmond Road, Johnsburg.
