Once vessels passed the lights and entered the harbor, they tied up mainly along the western edge of Round Lake down a gentle slope from Bridge Street. This is the Mason Street dock in the 1880s. As water traffic increased with continued improvement of the channel, Round Lake’s wharf and dock space, while extensive in the mid 1870s, began to come at a premium. Vessels often had to tie up one against the other until more docks went in, as did the schooner at right.
