“You see, it was this way,” went on Radovitch, settling back comfortably and smiling the pleased smile of reminiscence that sits on the face of a man who recalls events in which he has taken keen pride and enjoyment, “the most open approach to our mountain country was by the gorge up which ran the cart-road. There was a good-sized area of watershed draining out this way, so that the little river running through the gorge was a pretty powerful stream even in low water--a good bit bigger than the old Firehole in Yellowstone Park. This river flowed out of the main mass of the mountains into a fine bowl of an uplands valley, and then on out of that, through a rough range of foothills, in another gorge. At the head of this last gorge is a natural site to store water, and there--as a project of an old Government reclamation scheme that had been held up halfway for lack of money to go on with--a high dam had been built which backed up a deep, narrow lake four or five miles long. “The Austrians had a small force in the little village in the valley of the lake, and patrolled four or five miles of the cart-road into the mountains, but the main lot of them were camped below the second gorge in an open, triangle-shaped valley that ran up from the plain to the foothills. It was a good, safe, healthy, well-drained camp, well above the top marks of spring high-water. The only threat to it was the lake behind the dam in the valley above, but, unluckily for them, they didn’t know all the facts about that dam. “The truth was that this dam was built to hold up a lake half again as deep as the one then there, but poor engineering and scamp contracting combined to make it too weak to stand the pressure up to the level intended. The English engineer who came to inspect it put a mark about two-thirds of the way up, and warned that it wouldn’t be safe to ever let the water rise above that height. As a precaution, it had been the custom every February or March, before the spring thaw came, to drain off the water of the lake during the month or two before the run-off was the greatest, so that there was plenty of margin against the floods shoving up the level above the danger-point. The Austrians were good enough engineers to know that it was a rotten dam, but they didn’t seem to have the sense to start lowering the water level before the spring freshets set in.
