The available information at the time provided information on the level of freight movements on a waterway. We used that as an indication of the level of commercial activity.
The information around the recreational use was less detailed and less informative. We drew upon information the program had on where projects had been engaged in on waterways and where users had come forward to indicate that they were using the waterways.
It was information that was perhaps more precise for the freight and more precise for which waters were charted or not charted. The information around the recreational users, I would say, was of a less comprehensive nature, if that answers your question.
