The Fox River is back open to watercraft in the WSPY listening area.

The Kendall County Sheriff's Office shared a message from the Fox Waterway Agency that indicates the river is open to full boating with a debris advisory in effect.

The announcement comes after it was announced in late May that due to high water levels and a swift current the Fox River would be closed from the Stratton Lock and Dam, south to the Bridge St. bridge in Millington in Lake, McHenry, Kane and Kendall Counties.

As boaters and swimmers head out to waterways in the upcoming summer months, residents are advised to be on the lookout for blue-green algae in Illinois lakes and rivers.

Blue-green algae can produce toxins that are dangerous to people and pets.

It becomes more prevalent when the temperatures rise and can look like spilled green or blue-green paint, surface scum or greenish globs suspended in the water. This is State EPA Biologist Teri Holland.

Those exposed could suffer a rash, hives, diarrhea and vomiting.

If you do come in contact with blue-green algae, Holland recommends rinsing off with fresh, clean water as soon as possible.
