Arnold Creek (Huntington Creek tributary)

Arnold Creek begins in a deep valley in Ross Township, only a few thousand feet from the edge of the watershed of Bowman Creek. It flows south-southwest for a few tenths of a mile before turning south-southeast for several tenths of a mile. The creek then receives an unnamed tributary from the left and flows south for more than a mile and its valley deepens. In this stretch, it receives two more unnamed tributaries: one from the left and one from the right. The creek's valley then becomes much shallower as it turns south-southwest and then south, crossing Pennsylvania Route 118 near the community of Kyttle. South of Pennsylvania Route 118, the creek turns south-southwest and flows around a bend before turning south-southeast for approximately a mile and a half. Its valley deepens again until the creek leaves the valley and reaches its confluence with Huntington Creek. Tributaries Arnold Creek has no named tributaries. However, it does have three unnamed tributaries. ==Hydrology and geography==

Upstream of Pennsylvania Route 118, the concentration of alkalinity in Arnold Creek is 4 milligrams per liter. Downstream of Pennsylvania Route 118, the alkalinity concentration in the creek increases to 5 milligrams per liter. The elevation near the mouth of Arnold Creek is above sea level. The elevation of the creek's source is approximately above sea level. ==Watershed==

The watershed of Huntington Creek has an area of . Upstream of Pennsylvania Route 118, 63 percent of the creek's length is open to the public. The remaining 37 percent is private land that is closed to the public. Downstream of Pennsylvania Route 118, only 59 percent of its length is open to the public. The remaining 41 percent is on private land that is closed to the public. A portion of Arnold Creek is in Pennsylvania State Game Lands Number 206. ==History==

Arnold Creek was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1168410. Additionally, there is a bridge carrying Pennsylvania Route 118 over the creek west of State Route 4028. Plans were made in 1996 to rehabilitate the bridge for an estimated cost of $3,000. The entire length of the creek were designated as Class A Wild Trout Waters in 1999. ==Biology==

Two sections of Arnold Creek are considered by the Pennsylvania Fish and Boat Commission to be Class A Wild Trout Waters. One section is approximately long and runs from the creek's headwaters to Pennsylvania Route 118. The other section is approximately long and runs from Pennsylvania Route 118 to the creek's mouth. Both sections are Class A Wild Trout Waters for brook trout. The others are Mitchler Run, Shingle Run, Lick Branch, Phillips Creek, and part of Kitchen Creek. There is a young stand of beech trees growing on Arnold Creek. ==See also==
