Image showing the main dam at the St. Croix Paper Mill. The long brick building at the left of the image contains the hydro-mechcanical turbines that were used to grind the 4 foot softwood pulpwood logs into slush pulp that would be sent to the paper machines. This is called groundwood pulp and contains all of the wood fiber and lignin and is normally used to make newsprint. The main investor in the Woodland mill was the Boston Globe. Note the headgates at the top of the dam above the brick building. They control the amount of water fed to the turbines. Not seen on the other side of the brick building is a section of the dam. Seen to the right of the image is another section of the dam holding back the mill pond formed by the St Croix River. Of interest is that section of the dam is in Canada as the mill pond straddles the US/Canada border. Note water spilling over the top of the dam in the white areas. The vertical wooden structure is the powerline tower for electricity coming from Grand Falls hydro-electrical dam located several miles up river. The wooden structure nearest to the buidling is a sluice to remove floating debris from the mill pond. The wooden crib structure is believed to be the original fishway. The curved concrete sections below the brick building are the tailraces for the groundwood turbines that return the mill pond water to the St Croix River.
