A dredge being assembled on Ohio’s largest inland lake will be used to remove silt on the lake floor and reduce the threat of toxic algae blooms that hurt area tourism in recent years.

The algae produce a nerve toxin that can sicken humans and kill pets and other animals.

The Lima News reports parts for the new 57-ton craft were unloaded last week at Grand Lake St. Marys State Park. The Ohio Department of Natural Resources says the crew hoped to have the boat ready to launch in a few days, but more work was needed to make the 67-foot-long craft operable.

The 12-inch suction dredge named “Brutus” will help remove silt that collects on the lake floor and is rich in phosphorus that feeds the algae blooms.
