It is 3.8 miles (6.1 km) long.[2] The stream flows through Mount Pleasant Township and Orange Township. The annual load of sediment in it is 8,522,400.0 pounds (3,865,695.6 kg). The stream's watershed has an area of 6.1 square miles, most of which is agricultural land. There are also large areas of forested land in the watershed.

Course

Deerlick Run starts in northern Mount Pleasant Township, near the community of Welliversville. It flows southeast for a number of miles in a fairly shallow valley to the eastern part of Mount Pleasant Township. Here, the stream turns eastward and exits Mount Pleasant Township. Upon exiting the township, it enters Orange Township. The stream then exits its valley and enters a plain. Shortly afterwards, it reaches its confluence with Fishing Creek. The confluence is slightly north of Pennsylvania Route 487 and slightly south of a gauging station.[3]

Deerlick Run has no named tributaries.[3]

Hydrology and climate

The daily load of sediment in Deerlick Run is 23,349.0 pounds (10,590.9 kg), which equates to an annual load of 8,522,400.0 pounds (3,865,695.6 kg). The total maximum daily load for sediment in the stream is 14,599.0 pounds (6,622.0 kg) per day, or 5,328,648.0 pounds (2,417,034.1 kg) per year. 7,898,600 pounds (3,582,700 kg) of sediment per year comes from croplands and 451,600 pounds (204,800 kg) comes from pastures or hay. 90,000 pounds (41,000 kg) comes from stream banks, 40,800 pounds (18,500 kg) comes from land classified as "transition" by the Pennsylvania Department of Environmental Protection, 23,200 pounds (10,500 kg) comes from forests, and 18,200 pounds (8,300 kg) comes from land classified as "low-intensity development" by the Pennsylvania Department of Environmental Protection.[4]

Deerlick Run experiences significant levels of siltation and stream bank erosion. The erosion coefficient of Deerlick Run ranges from 0.12 between September and March to 0.3 during the rest of the year.[4]

The average annual precipitation in the Deerlick Run watershed is 37.7 inches (96 cm). The average runoff rate in the watershed is 1.8 inches (4.6 cm) per year.[4]

Deerlick Run has little riparian buffering. No part of the stream or any of its tributaries attains the water quality standards of the Pennsylvania Department of Environmental Protection.[4]

History

In 1853, Deerlick Run was part of the border between Columbia County and Montour County.[5] However, in the 21st century, it is near the center of Columbia County.[2]

In the past, the valley of Deerlick Run was home to many industries, although little is known about them. The remains of a dam can be seen on the stream and there was once a gin mill, a sawmill, and a woolen mill.[1] A mill known as the Behm Mill was built on the stream in 1801.[6] An ice house also was once built near the stream.[1]

Biology

Deerlick Run is designated as a coldwater fishery because it can support fish species of the family Salmonidae. It is also designated as a migratory fishery because it is in the Susquehanna River watershed.[4]
