Lock Houses

Lock houses and other structures still stand along the 184 ½ mile canal. The lockkeepers and their families lived in the lock houses. In recent times the National Park Service occasionally opens some of the lock houses for visits but the public. Guides in period dress provide tours and lectures on the workings of the canal.

At Seneca there are remains of the Seneca Stone Mill, which was the center of the sandstone industry in the 19th Century. The Seneca Sandstone Company used the facilities of the canal to process the sandstone. The company installed a gate in the canal west of Seneca Creek, diverting water into the plant. Mules pulled uncut sandstone boulders in gondolas out of the quarries over a narrow gauge railroad track. Water fed by the canal, ran the turbines, which furnished the power for cutting the stone.
