Some of the water may also be coming from an unmapped deep mine entry. This site is also known as the “big weir discharge” because of the large size of the flow-measuring device that is in place. Average flow was 210 gpm, and the average pH was 3.7. This discharge is net acid. On average, this discharge contributed 179 lbs/day of acid, 10 lbs/day of iron, 52 lbs/day of manganese, and 13 lbs/day of aluminum to the unnamed tributary (Killer Trib) to Montgomery Creek."
