Dredging continues at Grand Lake St. Marys in an effort to get rid of phosphorus laden sediment at the bottom of the lake.
It's all part of a plan to help reduce the level of toxic algae in the lake.
It costs about three dollars a cubic yard to remove the material.
So far crews operating the three dredges are on schedule to remove 275 thousand cubic yards of sludge.
Grand Lake St. Marys parks manager Brian Miller says recent storms slowed them down just a bit but they should be back on schedule soon.
Miller says their newest dredge, Brutus, is moving to the south eastern part of the lake near the Otterbein retirement community this week.
Money to fund the dredge operation comes from the Division of Watercraft through boater registration fees and a percentage of the gas tax.
