Шаблон:Short description Шаблон:Infobox river Coal Run is a tributary of Shamokin Creek in Northumberland County, Pennsylvania, in the United States. It is approximately Шаблон:Convert long and flows through Mount Carmel Township, Coal Township, and Shamokin.[1] The watershed of the stream has an area of Шаблон:Convert. The stream is designated as an impaired waterbody due to metals from abandoned mine drainage. It is an ephemeral stream. Virtually all of the watershed is in coal mining regions.

Various sawmills and coal mines have historically been constructed on Coal Run. A number of bridges have also been built across the stream. Its drainage basin is designated as a Coldwater Fishery and a Migratory Fishery and was historically inhabited by trout.

Course

Coal Run begins in a lake in Mount Carmel Township. It flows east-southeast through a valley for several tenths of a mile before entering Coal Township. The stream continues flowing east-southeast for more than a mile before turning south for a short distance. It then turns southwest for a few tenths of a mile before turning south for a few tenths of a mile. After this, the stream crosses Pennsylvania Route 61 and passes near the census-designated place of Ranshaw. The stream then flows in a west-northwesterly direction for several tenths of a mile, passing through the census-designated place of Marshalton before entering Shamokin. The stream then flows west for a few tenths of a mile until it reaches its confluence with Shamokin Creek.[1]

Coal Run joins Shamokin Creek Шаблон:Convert upstream of its mouth.[2]

Hydrology

The entire length of Coal Run is designated as an impaired waterbody. The cause of the impairment is metals and the source of the impairment is abandoned mine drainage.[3] The stream is one of several in the watershed of Shamokin Creek to be impacted by abandoned mine drainage, although it is not seriously impacted. However, it is fairly consistently neutral or alkaline, with an average pH of 6.5, though its pH can be as low as 4.8.[4][5] The stream's water comes from mine discharges such as the Greenough Mine discharge, the Nielson Mine discharge, and the Luke Fidler Mine discharge.[4] The stream is also impacted by raw sewage discharges.[5] In the early 1900s, mine water from the Richards No. 4 Colliery entered the stream. Numerous other streams of black waste water from other collieries discharged into the stream as well.[6]

Coal Run is an ephemeral stream.[4] In 1999 and 2000, its discharge ranged from Шаблон:Convert. The temperature of the stream ranged from Шаблон:Convert and the specific conductance ranged between 613 and 627 micro-siemens per centimeter at Шаблон:Convert. The concentration of water hardness ranged from Шаблон:Convert in the two times it was measured. The concentration of total suspended solids was Шаблон:Convert in 2000, while the concentration of total dissolved solids was Шаблон:Convert. The turbidity of the stream ranged from 0.0 to 4.0 Nephelometric Turbidity Units.[7]

In 2000, the concentrations of recoverable sodium and potassium in Coal Run were Шаблон:Convert. The concentrations of recoverable magnesium and calcium were Шаблон:Convert. The concentrations of recoverable manganese and iron were Шаблон:Convert, while the concentration of recoverable aluminum was less than Шаблон:Convert.[7]

In 1999 and 2000, the concentration of dissolved oxygen in Coal Run ranged from Шаблон:Convert, while the carbon dioxide concentration was Шаблон:Convert both times it was measured. In 2000, the nitrogen concentration was Шаблон:Convert. The phosphorus concentration was Шаблон:Convert. The silica concentration in the stream's filtered water was Шаблон:Convert, the sulfate concentration ranged from Шаблон:Convert and the chloride concentration ranged from Шаблон:Convert. The concentration of nitrite was less than Шаблон:Convert, while the ammonia concentration in unfiltered water was Шаблон:Convert.[7]

Geography and geology

The elevation near the mouth of Coal Run is Шаблон:Convert above sea level.[8] The elevation of the stream's source is between Шаблон:Convert above sea level.[1]

Coal deposits occur in the watershed of Coal Run.[9] There are also underground mine complexes in the vicinity of the stream. Almost all of the watershed is in the Coal Region.[4]

In the early 1900s, fine culm was carried into Coal Run via waste water streams from collieries. However, there were no large culm deposits on the stream below the Hickory Ridge Colliery. Trash and sewage entered the stream at Shamokin.[6]

Watershed

The watershed of Coal Run has an area of Шаблон:Convert.[2] The mouth of the stream is in the United States Geological Survey quadrangle of Shamokin. However, its source is in the quadrangle of Mount Carmel.[8]

The designated uses of Coal Run are coal water and migratory fishes.[10]

History

Coal Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1172073.[8] The stream is also known as Coal Run Creek.[11]

John C. Boyd constructed a sawmill on Coal Run in the early 1800s.[12] Coal mining was being occasionally done in the vicinity of the stream by 1825. In 1828, Daniel Derk opened a mine on Coal Run near a public road that crossed the stream. Derk was injured while working in this mine, making him the first miner to be injured in Northumberland County.[13]

A railroad bridge historically crossed Coal Run.[9] In the early 1900s, J.H. & C.K. Eagle, Inc. requested permission to construct a coal dredging plant on the bank of the stream.[11]

In the early 1900s, there were several collieries and washeries in the watershed of Coal Run. These included the Hickory Ridge Colliery, the Luke Fiddler Colliery, the Hickory Swamp Washery, the Natalie Colliery, and the Colbert Colliery. The first three were owned by the Susquehanna Coal Company, the fourth was owned by the Colonial Collieries Company, and the fifth was owned by the Shipman Coal Company.[6]

A concrete slab bridge carrying State Route 2026 over Coal Run was built in 1938. It is Шаблон:Convert long and is located in the village of Coal Run. A concrete channel beam bridge carrying State Route 2017 was built over the stream in 1952 and repaired in 2007. This bridge is Шаблон:Convert long and is located in the village of Springfield. A concrete culvert bridge was built over the stream Шаблон:Convert south of Paxinos in 1970. This bridge is Шаблон:Convert long and carries State Route 8001.[14]

Biology

The drainage basin of Coal Run is designated as a Coldwater Fishery and a Migratory Fishery.[15] Historically, in around 1840, the stream was "filled with trout".[12]
