Zerbe Run (also known as Zerbe Creek ) is a tributary of Mahanoy Creek in Northumberland County , Pennsylvania . The 13.4 km long river flows through Coal Township , Zerbe Township and Little Mahanoy Township . The catchment area of the river has a size of 34 km². In the lower reaches of the river is polluted by earlier mining , but the upper reaches is unpolluted. Several mines drain the river or its tributaries; the Zerbe Run is near the Western Middle Anthracite Field .

Zerbe Run is one of the larger tributaries of Mahanoy Creek, and its catchment area contributes 8.1 percent to the catchment area of ​​the receiving water . Numerous bridges cross the river.

Run

Zerbe Run in Trevorton

Zerbe Run has its source in a valley between two long mountain ranges ( Big Mountain and Little Mountain ) in the Coal Township. The stream initially flows a few hundred meters in a west-southwest direction into the Zerbe Township towards Trevorton . The body of water then flows through Zerbe Township and Trevorton for a few kilometers, flows through a pool and passes under Pennsylvania Route 890 . Then the Zerbe Run turns for a few hundred meters to the west-northwest, receives an unnamed tributary from the left and then resumes the west-southwest direction of flow. The river then passes under Pennsylvania Route 225 , which then follows the course of the river for several kilometers. A few hundred meters further, the Zerbe Run receives another tributary from the left and a few hundred meters further leaves the Zerbe Township and reaches the Little Mahanoy Township. Here the river turns to the southwest and follows this direction for almost two kilometers, with two more unnamed tributaries flowing from the left before the Zerbe Run reaches its confluence with Mahanoy Creek, 17.28 km above its own confluence with the Susquehanna River.

Hydrology

Some sections of the catchment area of ​​the Zerbe Run are considered to be polluted by wastewater from abandoned mining. The abandoned North Franklin Mine is being drained at four locations in the catchment area. Wetlands can be suitable for treating this pit water passively. At Trevorton there are large accumulations of silts along the stream . The impact of mine water on the water quality depends on how much unpolluted water flows in from the upper reaches.

In 2001, analyzes found that the Zerbe Run is acidic when the water is low, and the conditions are almost neutral when the water flow is higher. In March and August 2001, the average discharge on the upper reaches was 0.226 and 0.018 m³ / s and 7.4 km downstream to 0.855 and 0.123 m³ / s. In March and August 2001, the alkalinity of Trevorton was 11 and 49 mg / L and downstream were -3 and -20 mg / L, respectively. In March and August 2001 the pH of the watercourse at Trevorton was 7.0 and 7.2, and at the lower reaches 4.3 and 6.0, respectively.

In March 2001 the concentration of aluminum in the Zerbe Run at Trevorton was 0.04 mg / l, while in August of that year it was 0.02 mg / l. Downstream it reached 0.10 mg / L in March 2001 and 2.3 mg / L in August 2001. The manganese concentration at Trevorton was 0.06 and 0.02 mg / l, and 7.4 km downwards it was 0.93 and 2.7 mg / l, respectively, in March and August 2001. The concentration of the Dissolved oxygen in the watercourse was found to be 11.6 and 9.5 mg / l at Trevorton, while downstream in March and August 2001 it reached 11.5 and 8.8 mg / l, respectively.

The concentration of nitrates in the Zerbe Run was 0.5 mg / l at Trevorton in March and 0.72 mg / l in August 2001, while it reached 0.50 and 0.60 mg / l 7.4 km downstream. In the case of phosphorus , the content was 0.01 mg / l at both points in time for trevorton, and at the lower reaches 0.04 mg / l in March 2001 and 0.02 mg / l in August 2001. Sulphates were in March 2001 10 mg / l measured at Treverton and 99 mg / l downstream. In August 2001 values ​​of 8 mg / l were recorded for Trevorton and 264 mg / l downstream.

geography

Mouth of the Zerbe Run

The Zerbe Run flows out at a height of about 155 m above sea level. The source height is about 262 m.

The valley of the Zerbe Run lies between Big Mountain in the north and Little Mountain in the south and is about one and a half kilometers wide. The village of Trevorton lies in this valley. The Zerbe Run has no named tributaries. Of the four unnamed tributaries, the most upstream is by far the longest.

At the beginning of the 20th century, the Zerbe Run was 30 m wide and 1 m deep at its mouth, and the flow velocity was around 5 km / h. The headwaters of the river are formed by several springs east of Trevorton. Pit water from the south of Trevorton is discharged into the brook and is caused by the fact that it is polluted between Trevorton and the mouth.

The sediments have at Trevorton according to the Munsell color system , a dark brown color. Downstream the sediments are deep brown.

Catchment area

The catchment area of the Zerbe Run has a size of 34 km 2 . The mouth of the water is not far from Hunter in grid reference Sunbury of the United States Geological Survey and the source in grid reference Sunbury. On its course, the Zerbe Run crosses the Trevorton grid square.

The Zerbe Run is one of the more important watercourses in the Mahanoy Creek catchment area. It contributes 8.3% to the catchment area of ​​the receiving water . Most of the abandoned mining area is on the orographic left. In the catchment area there are several wetlands and ponds as well as a water reservoir.

The banks of the Zerbe Run can be significantly affected by floods . Groundwater is taken from two places in the catchment area .

Naming and bridges

The Zerbe Run is listed in the Geographic Names Information System under the number 1191948 and is also known as Zerbe Creek. In fact, it was a 1965 USGS map that incorrectly referred to the river as "Zerbe Creek". In 1969 civil engineer Stephen P. Pousardien pointed out that all other references related to the term "Zerbe Run" and that it was also used by locals. Once the river was also known as Little Mahanoy Creek; however, there is another tributary of Mahanoy Creek called Little Mahanoy Creek .

In 1904 a steel girder bridge was built in Trevorton, which leads 8th Street over the Zerbe Run. The structure was repaired in 1997 and is 8.2 m long. A 11.6 m long concrete T-girder bridge was built in Trevorton for the Pennsylvania Route 225 in 1934 . A steel girder bridge has been running across the river on Raker State Route 3004 since 1950. The 18.3 m long structure was repaired in 2010. In 1996, a 7.3 m wide concrete culvert was built southwest of Trevorton .

Part of the Pennsylvania State Game Lands Number 165 lie in the northeast corner of the catchment area of ​​the Zerbe Run.

fauna and Flora

The catchment area of ​​the Zerbe Run is designated as Coldwater Fishery and Migratory Fishery. In 2001, invertebrates were observed in Trevorton and Dornsife , but no fish. Trout were used in a pond in the Zerbe Run catchment area, the Zerbe Run Rod And Gun Club Pond .

In 2001, Hydropsychidae and Philopotamidae were common (25–100 specimens) in the Trevorton count, and Leuctridae , Perlidae , Elmidae, and Crydalidae were common (10–24 specimens). Cambaridae , mosquitoes and dragonflies were present (3–9 specimens). Tipulidae , Simuliidae and Baetidae were rare with 1 or 2 specimens. At the other place where the Zerbe Run was examined in 2001, in addition to the aforementioned taxa, there were also gnats , Hydropsychidae , mudflies, and mermaids , and all of them were rare.

Juncus biflorus , Bartonia paniculata and Lactuca hirsuta and another endangered species are native to Zerbe Run in Zerbe Township and Coal Township. Canadian hemlock , red maple , yellow birch , cinnamon fern , royal fern , Carex laxiflora , trifoliate golden thread, and Maianthemum canadensis are also native to the area.

A portion of the run near its headwaters is listed in the Northumberland County Natural Areas Inventory.
