Mehoopany Creek and Little Mehoopany Creek. Biology Wild trout naturally reproduce in Farr Hollow from its headwaters downstream to its mouth. The stream is classified as a Coldwater Fishery. However, in 2001, these wild brook trout populations were noted to be sparse. In the 2001 study by the Pennsylvania Fish and Boat Commission, a total of 11 fish species were observed by electrofishing in the lower reaches of Farr Hollow. Three wild brook trout were observed, with lengths ranging from , along with one hatchery brook trout stocked by local landowners. The low trout populations were primarily due to difficulty for fish to physically access the stream. Other fish species observed in Farr Hollow in the 2001 study include central stonerollers, common shiners and golden shiners, blacknose dace and longnose dace, creek chub, white sucker, brown bullhead, pumpkinseed, and sculpins.
