Jahns Valley Creek is an eight-mile creek that flows the length of the Jahns Valley
Subwatershed; one of the smaller subwatersheds in the Waumandee Creek Watershed.
Downstream sections of the creek have been widened and channelized. Pasture borders the
majority of the stream with livestock permitted access to the creek, resulting in trampled stream
banks in the downstream portion of Jahns Valley Creek. Grazed woodlot and pasture contribute
the majority of sediment to the creek. Sand and silt creek bottom, poor shading, and elevated
water temperatures yield a poor fish habitat1. Jahns Valley Creek supports a warm water forage
fishery, with potential to support a Class III trout fishery. A fish survey conducted in 2001 found
7 brown trout out of 25 fish total. Speculation is that the brown trout found in the creek were
