|Located in Cumberland County, Big Spring
Creek can be characterized as a fertile limestone spring. Big Spring Creek offers anglers the opportunity
to fish for wild trout in the Catch and Release Fly-Fishing
Only section or fish for stocked trout
in the section open to angling under Statewide Regulations. Anglers
are fortunate that the Pennsylvania Fish and Boat Commission (PFBC) owns a corridor along a significant portion of
the upper end of Big Spring Creek, which offers protection as well as access to this popular stream.
Biologists and technicians from the PFBC Fisheries Management Division continue their annual monitoring of the trout populations in Big Spring Creek following the closure of the Big Spring State Fish Culture Station in November 2001. This survey will provide insight for future fisheries management plans.
Big Spring Creek is stocked with adult and fingerling hatchery reared brook trout. The fingerling brook trout are stocked from Thomas Dam (Old Fish Barrier) downstream to the Laughlin Mill Dam in Newville. Adult brook trout are stocked from Nealy Road downstream to the Laughlin Mill Dam in Newville. A distinguishing fin clip given to all of the hatchery reared brook trout stocked into Big Spring Creek allow biologists and technicians to determine the origin (hatchery or wild) of brook trout collected during the annual surveys of Big Spring Creek. Fingerling brook trout have their left pelvic fin clipped while adult brook trout have the adipose fin clipped. The specific number of adult and fingerling hatchery reared trout that were stocked into Big Spring Creek and the number that were subsequently collected during sampling are reflected in the table below. Hatchery reared fingerling brook trout survival has been poor, with less than 3% of the fingerlings being collected during sampling the following year regardless of whether they were stocked in the fall or spring. Adult hatchery reared brook trout survival rates were not determined as these fish were planted into areas where immediate harvest is allowed and with the expectation that recreational anglers will harvest a majority of these fish.
* Increased number of fingerlings stocked in 2006 was due to hatchery production changes that produced a smaller sized fingerling therefore numbers were increased to compensate.
A total of 235 wild brook trout were collected during the 2006 electrofishing survey conducted in the 150 meter “ditch” station. Wild brook trout were between 2 and 12 inches in total length. Wild rainbow trout collected from the “ditch” ranged from 4 to 15 inches in total length and numbered 28. Brown trout collected from the “ditch” ranged from 17 to 21 inches in total length and numbered 3.
A total of 162 wild brook trout were collected during the 2006 electrofishing survey conducted in the station located 300 meters downstream of the ditch and were 2 to 16 inches in total length. Wild rainbow trout in this station ranged from 4 to 14 inches in total length and numbered 135. Brown trout in this station ranged from 4 to 24 inches in total length and numbered 6. Habitat restoration work was completed in June of 2004 in the lower portion of this sampling site.
A total of 13 wild brook trout were collected by electrofishing from the station located 300 meters downstream of the Fish Barrier during the 2006 survey. These fish were between 3 to 11 inches in total length. Wild rainbow trout in this station ranged from 4 to 22 inches in total length and numbered 164. Brown trout in this station ranged from 4 to 20 inches in total length and numbered 3.
As was found in previous surveys low numbers of hatchery trout were collected in 2006 at the 100 meter (328 feet) stone arch bridge sampling station as well as the 100 meter (328 feet) sampling station below Laughlin Mill Dam in Newville. In 2006 two additional 300 meter (984 feet) stations were sampled in the vicinity of Nealy road. Low numbers of hatchery and wild trout were collected at both of these stations.
Other species found during the survey included white sucker, longnose dace, blacknose dace, pearl dace, tessellated darter, fourspine stickleback and sculpin.
