It's late winter as I walk through Hogback Ridge Preserve, and the only tracks on the trails besides mine are those left after the snowfall by deer and squirrels.

The Delaware County Historical Society will recognize the 100th anniversary of the 1913 Delaware flood with several programs, beginning at 10 a.m. Monday, March 25, when a commemorative plaque will be dedicated beside the pedestrian path between William and Winter streets, on the west bank of the Olentangy River.

Representatives from the city of Delaware and the Delaware County Historical Society will speak during the ceremony.

A program about the devastating flood and its grim aftermath will be held at 7 p.m. March 25, at Willis Intermediate School, 74 W. William St.

"The Great Flood of 1913: Could It Happen Again?," will feature DCHS president and local history expert Brent Carson and Ben O'Dell of the Army Corps of Engineers. Carson will show pictures of the flood and the damage it left behind and share information reported in 1913 newspapers. Carson also will show never-before-seen video clips of flood survivors describing their personal experiences.

O'Dell, the Delaware Dam's resource manager, will discuss flood control in the county, including how water levels in Delaware Lake, the Olentangy River and the Ohio River are handled.

The Willis program is free and open to the public.
