- Source: Deep Creek (Mahantango Creek tributary)
Deep creek" target="_blank">Creek is a tributary of Mahantango creek" target="_blank">Creek in Dauphin County, Pennsylvania, in the United States. It is approximately 5.9 miles (9.5 km) long and flows through Lykens Township and Pillow. The watershed of the creek" target="_blank">creek has an area of 10.6 square miles (27 km2). It is not designated as an impaired waterbody, but is nevertheless observed to have high nitrate concentrations. Major land uses in the creek" target="_blank">creek's watershed include agricultural land and forested land. The creek" target="_blank">creek's watershed is classified as a Warmwater Fishery.
Course
Deep creek" target="_blank">Creek begins in a pond in Lykens Township. It flows north for several tenths of a mile, passing through three more ponds, before turning west-northwest. After several tenths of a mile, the creek" target="_blank">creek turns west-southwest for several tenths of a mile before receiving an unnamed tributary from the right and heading in a westerly direction for several tenths of a mile. In this reach, it receives one unnamed tributary from the right and one from the left. It then meanders west-northwest for several tenths of a mile before turning west-southwest for more than a mile. In this reach, the creek" target="_blank">creek receives one unnamed tributary from the right and one from the left. It eventually makes several meanders in a northwesterly direction, receiving three unnamed tributaries from the left and one from the right. The creek" target="_blank">creek then flows north-northwest through a water gap in Mahantango Mountain for a few tenths of a mile, entering Pillow. Here, an unnamed distributary of the creek" target="_blank">creek splits off from the left bank to the north and the creek" target="_blank">creek itself turns north-northeast. A few tenths of a mile further downstream, it reaches its confluence with Mahantango creek" target="_blank">Creek.
Deep creek" target="_blank">Creek joins Mahantango creek" target="_blank">Creek 10.30 miles (16.58 km) upstream of its mouth.
Hydrology
Deep creek" target="_blank">Creek is not designated as an impaired waterbody as of 2004. However, the Dauphin County conservation District has observed that nitrate concentrations in the creek" target="_blank">creek are among the highest in Dauphin County. It is also likely that sediment loads are relatively high.
Geography and geology
The elevation near the mouth of Deep creek" target="_blank">Creek is 482 feet (147 m) above sea level. The elevation near the creek" target="_blank">creek's source is 741 feet (226 m) above sea level.

The creek" target="_blank">creek also passes through the quadrangle of Klingerstown. Its mouth is located at Pillow.
The main land use in the upper reaches of the watershed of Deep creek" target="_blank">Creek is agricultural land. However, there are blocks of various other land uses in this area as well. In the lower reaches, forested land dominates, except for an area in the vicinity of the creek" target="_blank">creek's mouth.

A cotton mill and a saw mill historically existed on Deep creek" target="_blank">Creek.
A concrete frame bridge carrying State Route 1009/N. Cross Road over Deep creek" target="_blank">Creek was constructed 1 mile (1.6 km) south of Pillow in 1985 and is 24.0 feet (7.3 m) long. In 2013, it was proposed that the $610,432 Growing Greener County Environmental Initiative Program be redesignated to several projects, including the protection and repair of stream banks along the creek" target="_blank">creek. In 2015, a permit was issued to discharge stormwater into Deep creek" target="_blank">Creek during construction operations.
Biology
The drainage basin of Deep creek" target="_blank">Creek is classified as a Warmwater Fishery. Macroinvertebrate samples from the creek" target="_blank">creek encountered eleven types per sample, but only four that were pollution-sensitive.
Deep creek" target="_blank">Creek generally lacks adequate riparian buffers, although the main stem of Mahantango creek" target="_blank">Creek has greater buffering. In 2008, a site on the creek" target="_blank">creek near Luxembourg Road was classified as being in "poor" health. Hilsenhoff Biotic Index values indicated that organic pollution in the watershed was likely.
