Twenty miles up Conemaugh creek, beyond the workingmen’s villages of South Fork and Mineral Point, was Conemaugh lake. It was a part of the old and long disused Pennsylvania Canal system. At the head of Conemaugh creek, back among the hills, three hundred feet or more above the level of Johnstown streets, was a small, natural lake. When the canal was building, the engineers took this lake to supply the western division of the canal which ran from there to Pittsburgh. The Eastern division ended at Hollidaysburgh east of the summit of the Alleghanies, where there was a similar reservoir. Between the two was the old Portage road, one of the first railroads constructed in the State. The canal was abandoned some years ago, as the Pennsylvania road destroyed its traffic. The Pennsylvania Company got a grant of the canal from the State. Some years after the canal was abandoned the Hollidaysburgh reservoir was torn down, the water gradually escaping into the Frankstown branch of the Juniata river. The people of the neighborhood objected to the existence of the reservoir after the canal was abandoned, as little attention was paid to the structure, and the farmers in the valley below feared that the dam would break and drown them. The water was all let out of that reservoir about three years ago.

The dam above Johnstown greatly increased the small natural lake there. It was a pleasant drive from Johnstown to the reservoir. Boating and fishing parties often went out there. Near the reservoir is Cresson, a summer resort owned by the Pennsylvania road. Excursion parties are made up in the summer time by the Pennsylvania Company, and special trains are run for them from various points to Cresson. A club called the South Fork Fishing and Hunting Club was organized some years ago, and got the use of the lake from the Pennsylvania Company. Most of the members of the club live in Pittsburgh, and are prominent iron and coal men. Besides them there are some of the officials of the Pennsylvania road among the members. They increased the size of the dam until it was not far from a hundred feet in height, and its entire length, from side to side at the top, was not far from nine hundred feet. This increased the size of the lake to three miles in length and a mile and a quarter in width. It was an irregular oval in shape. The volume of water in it depended on the time of the year.

Some of the people of Johnstown had thought for years that the dam might break, but they did not think that its breaking would do more than flood the flats and damage the works of the Cambria Company.

When the Hunting and Fishing Club bought the site of the old reservoir a section of 150 feet had been washed out of the middle. This was rebuilt at an expense of $17,000 and the work was thought to be very strong. At the base it was 380 feet thick and gradually tapered until at the top it was about 35 feet thick. It was considered amply secure, and such faith had the members of the club in its stability that the top of the dam was utilized as a driveway. It took two years to complete the work, men being engaged from ’79 to ’81. While it was under process of construction the residents of Johnstown expressed some fears as to the solidity of the work, and requested that it be examined by experts. An engineer of the Cambria Iron Works, secured through Mr. Morrell, of that institution, one provided by Mr. Pitcairn, of the Pennsylvania Railroad, and Nathan McDowell, chosen by the club itself, made a thorough examination. They pronounced the structure perfectly safe, but suggested some precautionary measures as to the stopping of leaks, that were faithfully carried out. The members of the club themselves discovered that the sewer that carried away the surplus or overflow from the lake was not large enough in times of storm. So five feet of solid rock were cut away in order to increase the mouth of the lake. Usually the surface of the water was 15 feet below the top of the dam, and never in recent years did it rise to more than eight feet. In 1881, when work was going on, a sudden rise occurred, and then the water threatened to do what it did on this occasion. The workmen hastened to the scene and piled débris of all sorts on the top and thus prevented a washout.

For more than a year there had been fears of a disaster. The foundations of the dam at South Fork were considered shaky early in 1888, and many increasing leakages were reported from time to time.

“We were afraid of that lake,” said a gentleman who had lived in Johnstown for years; “We were afraid of that lake seven years ago. No one could see the immense height to which that artificial dam had been built without fearing the tremendous power of the water behind it. The dam must have had a sheer height of 100 feet, thus forcing the water that high above its natural bed, and making a lake at least three miles long and a mile wide, out of what could scarcely be called a pond. I doubt if there is a man or woman in Johnstown who at some time or other had not feared and spoken of the terrible disaster that has now come.

“People wondered, and asked why the dam was not strengthened, as it certainly had become weak; but nothing was done, and by and by they talked less and less about it, as nothing happened, though now and then some would shake their heads as if conscious the fearful day would come some time when their worst fears would be transcended by the horror of the actual occurrence.”

There is not a shadow of doubt but that the citizens of Cambria County frequently complained, and that at the time the dam was constructed a vigorous effort was made to put a stop to the work. It is true that the leader in this movement was not a citizen of Johnstown, but he was and is a large mine owner in Cambria County. His mine adjoins the reservoir property. He was frequently on the spot, and his own engineer inspected the work. He says the embankment was principally of shale and clay, and that straw was used to stop the leaking of water while the work was going on. He called on the sheriff of Cambria County and told him it was his duty to apply to the court for an injunction. The sheriff promised to give the matter his attention, but, instead of going before court, went to the Cambria Company for consul tation. An employee was sent up to make an inspection, and as his report was favorable to the reservoir work the sheriff went no further. But the gentleman referred to said that he had not failed to make public his protest at the time and to renew it frequently. This recommendation for an injunction and protest were spoken of by citizens of Altoona as a hackneyed subject.

Confirmation has certainly been had at South Fork, Conemaugh, Millvale and Johnstown. The rumor of an expected break was prevalent at these places, but citizens remarked that the rumor was a familiar incident of the annual freshets. It was the old classic story of “Wolf, wolf.” They gave up the first floors to the water and retired upstairs to wait until the river should recede, as they had done often before, scouting the oft-told story of the breaking of the reservoir.
