"I was 10 years old, and my mother was helping out with the U.S. Census," he said. "She had to go out to the canal to count the squatters living there, and she didn't want to go by herself."
So Mr. Robertson went along-and immediately became enchanted with the canal's aging earthworks, stone bridges and the unspoiled beauty of the nearby Savannah River shoals.
Many years later, as an engineer, he learned to appreciate the canal's intricate design and functionality as a source of drinking water and hydropower that transformed Augusta into an industrial empire.
Today, as a longtime member of the Augusta Canal Authority, he marvels at how much has been accomplished in the decade since local preservationists and the National Park Service convinced Congress and the president to create the Augusta Canal National Heritage Area.
Fans of the canal will recognize that milestone today with a celebration at the canal headgates from 1 to 5 p.m., with food, entertainment, boat rides and the dedication of a new bridge and the restored locks.
Many improvements have been made to the canal since the first master plan was devised in 1993 - three years before its Congressional designation.
Among them are the Interpretive Center and Petersburg Boat tour program based at Enterprise Mill, where more than 44,000 people have enjoyed tours and rides. Historic buildings at the headgates have been restored, and the aging wooden pavilion once again resonates with dancers' feet.
How has it all affected Augusta?
"It gives a different reason for people to visit Augusta," Mr. Robertson said. "It took a long time for the canal to even be listed among all the things to do in Augusta. Today I think it's in the forefront."
Although listed in 1975 on the National Register of Historic Places, the canal languished in neglect for many years - and portions of it were nearly lost to development, said Tom Swift, whose love affair with the waterway began when he moved here in 1973.
"As a new arrival, the thing that surprised me the most was that this riverfront community didn't have any idea where the river was or how to get to it," Dr. Swift said.
After years of fishing in the shoals and hunting quail in the quiet meadows along the towpath, Dr. Swift and his children were well acquainted with the waterway - and were disappointed to learn of a proposal in the early 1990s to create a golf course along its banks.
"When we found out a golf course was being planned for it, we thought that was the beginning of the end for the canal," he said, noting that opponents to the plan created a group known as Savannah Waterways Forum and demanded that public officials preserve the site and not sell it off.
The master plan that evolved from the input of residents led to the creation of the National Heritage Area that was formally signed into existence by President Clinton on Nov. 12, 1996.
