Pittsburgh, alone, suffered $6,500,000 damage during three floods from March 15, 1907, to March 20, 1908, and SI 7,000,000 during the twenty years ending in 1907, and during that year the damage in the Ohio Valley was estimated at $100,000,000.

Variation of Flow--In spite of all these enormous quantities of water going to waste and leaving death and destruction in their wake, one finds these same streams a few months away with insufficient water for any useful purpose. The comparative high and low water flows of certain streams in Pennsylvania are shown in Table I: TABLE I Comparative High And Low Flow Records Of Certain Streams In Pennsylvania Effects of Low Water--Navigation--The troubles due to these low stages are nearly as serious and costly, though not so spectacular, as those clue to floods. The low water flow of the Monongahela River (160 cubic feet per second) is only about two-thirds of the quantity necessary to operate the present locks at their full capacity, even without making any allowance for losses by evaporation and leakage.
