GLEN ELLYN, IL — An active algal bloom is prompting the Forest Preserve District of DuPage County to urge visitors to keep their dogs out of the water at East Branch Forest Preserve.
The algal bloom was confirmed at the off-leash area of the preserve on Monday.

Forest preserve officials say the bloom can resemble brown, blue or green paint on the water's surface.
