The Erie Canal is currently in a bicentennial period — construction on the canal broke ground in 1817 near Rome and was celebrated as complete in 1825 — but 2018 also marks the 100th year since the completion of the New York State Barge Canal. The Perinton Historical Society, on Tuesday, will host a lecture about the three eras of the Erie Canal, from "Clinton's Ditch" of the early-1800's and the enlarged canal system completed in 1862 to the current barge canal system. Speaker Bruce Schwendy, a retired manufacturing engineer who has long studied the canal and regularly travels it on a 40-foot houseboat, will discuss the canal's history and its folklore in "The Three Erie Canals."

"The Three Erie Canals: History and Folklore" will take place Tuesday, January 16, at the Fairport Public Library, 1 Fairport Village Landing. 7 p.m. Free, but reservations required. 223-9091; fairportlibrary.org.
