At the Lewistown Reservoir, which covers 6,000 acres, about a quarter of a mile of the west embankment was overflowed continuously for a day and a half. Waves dashed over the top of the south bank for several days. Both banks were almost despaired of, and a large force of men, including cottagers and citizens from neighboring towns, worked hard, placing logs and sand bags, to save them. In this they were successful, but a large area south of the reservoir was overflowed. The Loramie Reservoir of 1,830 acres was already filled to above the spillway level when the rain started, and the water reached a maximum elevation of about four feet above the 200 foot spillway. Two small crevasses about twenty and twenty-five feet wide respectively and five or six feet deep, were washed out at a low portion of the embankment. The Grand Reservoir is one of the largest artificial bodies of water in the world and covers about 13,400 acres. The water rose to about two feet above the ninety-five foot spillway. The water did not come near overtopping the banks, but heavy waves were driven against and over them, eroding them seriously at some points, and softening and furrowing their backs at others. A large force of volunteers worked with the laborers, filling and placing bags of sand, while a company of state militia patrolled the banks. No breaks occurred at any point, but the situation was critical for two or three days. [Illustration: REPAIRED BREAK IN LORAMIE RESERVOIR EMBANKMENT. When the break occurred the water was about four feet over the spillway. ] * * * * * These situations teach a lesson that ought never to need repetition. Reservoir failures did not contribute measurably to the flood damage in Ohio. The trouble was caused by excessive and extensive rains.
