The Kiskiminetas Drainage. As has been stated above, the Kiskiminetas River, at its point of union with the Allegheny, is in a fearful condition, the pollution consisting chiefly of mine water from the extensive coal regions of Westmoreland, Indiana, Cambria and Somerset Counties. In fact, we may say, that in almost all of the drainage basin of the Kiskiminetas fresh-water life is extinct. For the main stream, the Kiskiminetas-Conemaugh, this is true for its whole length, from above Johnstown in Cambria County downward. The Loyalhanna River from Latrobe downward is even worse than the Conemaugh. Black Lick Creek and its tributaries, Two Lick and Yellow Creeks, in Indiana County, are also polluted, and so is Stony Creek in Somerset County. There are, in the whole Kiskiminetas drainage, only very few streams possessing clear water and a tolerably well preserved fauna. In Westmoreland County we have a small stream, Beaver Run, which is good, and the Loyalhanna River above Latrobe contains a rich fauna. In Indiana County Blacklegs Run and the upper parts of Two Lick and Yellow Creeks are in good condition; in the lower part of Yellow Creek the fauna was destroyed during 1908. A mine had been opened in 1907 above Homer City, and the mine water discharged into the creek did its deadly work in the summer 1908, when the stage of the water for the first time after the opening of the mine became so low that the concentration of the pollution was great enough to kill the fauna. On July 23, 1908, the writer personally witnessed the actual destruction of the fauna, and the number of dead and dying fishes seen in Yellow Creek at Homer City was perfectly appalling.
