East Branch Rausch Creek is a tributary of Rausch Creek in Schuylkill County, Pennsylvania, in the United States. It is approximately 2.3miles long and flows through Porter Township and Hegins Township. The watershed of the creek has an area of 4.21sqmi. The creek is impacted by metals, pH, and siltation due to abandoned mine drainage and resource extraction. It drains an area between two mountains: Good Springs Mountain and Big Lick Mountain. There are also two mine pools in the watershed.
The main land use in the watershed of East Branch Rausch Creek is deciduous forest. However, disturbed land is the second-largest land use and accounts for the significant majority of the sediment loading in the creek. As of 2001, there are seven active mining permits in its watershed.
East Branch Rausch Creek begins in a valley on a mountain in Porter Township. It flows north for a few tenths of a mile before turning westreceiving an unnamed tributary from the rightand then northwest, soon crossing a road and entering Hegins Township. Here, the creek begins flowing in a roughly westerly or west-northwesterly direction through a larger valley for several tenths of a mile before heading in a southwesterly direction. After a short distance, it crosses a road and turns west for a short distance before turning west-northwest. Several tenths of a mile further downstream, the creek joins West Branch Rausch Creek to form Rausch Creek.
Reaches of East Branch Rausch Creek are designated as impaired waterbodies. The causes of impairment in these reaches include siltation, metals, and pH, while the sources include abandoned mine drainage and resource extraction.
The average discharge of East Branch Rausch Creek near its mouth was measured to be 1500000gal per day. The pH of the creek near its mouth ranged from 4.5 to 6.8, with an average of 5.75. The concentration of alkalinity ranged from 0to, with an average of 8.81mg/L.
The iron concentration in East Branch Rausch Creek near its mouth was found to range from 0.33to, with an average of 4.4mg/L. The manganese concentration ranged from 1.84to. The concentration of aluminum ranged between 0.23and, and averaged 3.15mg/L. The aluminum load requires a 95 percent reduction to meet the creek's total maximum daily load requirements, while the iron load requires a 94 percent reduction and the manganese load requires a 78 percent reduction. The acidity load requires an 84 percent reduction to meet its total maximum daily load requirements.
The annual load of sediment in East Branch Rausch Creek is 17628454.6lb. By far the largest contributor is disturbed land, which accounts for 16795923.8lb per year. Other contributors include deciduous forest (486781.7lb per year), cropland (333228.2lb per year), high-intensity urban land (9571.8lb per year), mixed forest (2342.3lb annually), coniferous forest (493.4lb per year), and hay/pastures (113.4lb per year).
The elevation near the mouth of East Branch Rausch Creek is 869feet above sea level. The elevation near the creek's source is 1303feet above sea level.
The watershed of East Branch Rausch Creek is situated between Good Springs Mountain and Big Lick Mountain. The headwaters of the creek are in a large abandoned strip mine.
There are two mine pools in the watershed of East Branch Rausch Creek: the Good Spring No. 1 Pool and the Good Spring No. 3 Pool. The former discharges into the creek via the Orchard Airway at an elevation of 1104feet above sea level and has discharges ranging from 180000gal2700000gal per day, with an average of 320000gal per day. The latter mine pool does not discharge into the watershed of East Branch Rausch Creek, but instead discharges via the Tracy Airway into the watershed of Good Spring Creek, a tributary of Swatara Creek.
The watershed of East Branch Rausch Creek has an area of 4.21sqmi. East Branch Rausch Creek is entirely within the United States Geological Survey quadrangle of Tower City. There are approximately 2.52miles of streams in the watershed. The headwaters of the creek are about two miles (three kilometers) from the village of Good Spring, via State Route 4011.
The dominant land use in the watershed of East Branch Rausch Creek is forested land. Of the 2458.6acres of land in the creek's watershed, 1949.6acres is occupied by deciduous forest. Disturbed land is the second-largest land use, accounting for 306.4acres. Cropland occupies 93.9acres, mixed forest occupies 64.2acres, and deciduous forest occupies 24.7acres. A total of 17.3acres in the watershed is high-intensity urban development, and 2.5acres are hay/pastures.
The drainage basin of East Branch Rausch Creek is designated as a Coldwater Fishery.
East Branch Rausch Creek was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1173763.
As of 2001, there are seven permitted mining operations in the watershed of East Branch Rausch Creek. Only two of them have an NPDES permit, and only one of those two has an active discharge.
