Spies Run
Spies Run is a tributary of Catawissa Creek in Schuylkill County, Pennsylvania, in the United States. It is approximately long and flows through East Union Township. The stream has a pH that is fairly close to neutral. The stream is in the United States Geological Survey quadrangle of Conyngham. Trout naturally reproduce in it.
Course
Spies Run begins on a mountain in East [Union Township, Schuylkill County, Pennsylvania|East Union Township], a few hundred feet from the border between East Union Township and Kline Township. It flows northwest in a narrow valley for several tenths of a mile. The stream then receives an unnamed tributary and turns north-northwest, entering a much broader valley. After a few tenths of a mile, it turns northwest and crosses a road. Within several hundred feet, the stream reaches its confluence with Catawissa Creek.Spies Run arrives at its confluence with Catawissa Creek upstream of the mouth of the creek.
Hydrology
Spies Run is described as a "clean stream" in the January 2013 Progress Report for the Eastern Pennsylvania Coalition for Abandoned Mine Reclamation. An extremely low pH was once observed in the stream using two water chemistry units. However, laboratory analysis of water samples for the stream determined that its pH was significantly closer to neutral. The pH measurements observed in the field are considered to erroneous, while the pH measurements observed in the laboratory are considered to be correct.Geography
The elevation near the mouth of Spies Run is above sea level. The elevation of the stream's source is between and.Spies Run is in the United States Geological Survey quadrangle of Conyngham. The community of McAdoo is near the stream.
There is a mountain in the watershed of Spies Run. A spoon-like geographical feature a mile from Buck Mountain is present at the headwaters of the stream. This geographical feature contains a rock formation known as Formation No. XII.
