Chapter 3. Water Resources
Cold Water Fishery (HQ-CWF). The tributaries that join Allegheny Portage Creek are CWF, except for
Brown Hollow and Fair Run, which are HQ-CWF.
Potato Creek
Potato Creek starts in southern McKean County in
Norwich Township, and flows in a northern direction
through Smethport to Coryville, where it joins the
Allegheny River. The mainstem of Potato Creek is a TSF
from its source to Cole Creek. From Cole Creek to the
mouth, it is designated as a Warm Water Fishery (WWF).
The tributaries that join Potato Creek vary between CWF
and HQ-CWF except for the South Branch of Cole Creek,
which is designated as an Exceptional Value (EV)
waterway. Table 3-1 identifies the HQ-CWF streams within
the Potato Creek subwatershed.
Oswayo Creek
Oswayo Creek starts in Genesee Township, and flows
in a western direction through Oswayo Borough and
Shinglehouse Borough, and joins the Allegheny River south
of Portville, New York. Oswayo Creek is designated as a
CWF, except for the segment from Brizzee Hollow to Clara
Creek, which is designated as a HQ-CWF. The tributaries that join Oswayo Creek vary between CWF and
HQ-CWF, except for South Branch Oswayo Creek, which is designated as an EV waterway. There are
seven waterways within the Oswayo Creek subwatershed that have been designated as HQ-CWF; they
include Brizzee Hollow, Bradley Run, Elevenmile Creek, Cow Run, Butter Creek, Janders Run, and
Taylor Brook.
Tunungwant Creek
Tunungwant Creek begins in Bradford, where the east and west branches join to form the mainstem,
which flows in a northern direction and joins the Allegheny River near Riverside Junction, New York.
The mainstem is designated as a WWF, as is the Kendall Creek tributary. The tributaries that join
Tunungwant Creek vary between CWF and HQ-CWF, except for Railroad Run and Minard Run, which
are designated as EV waterways. The HQ-CWF waterways that flow into Tunungwant Creek include East
Branch Tunungwant Creek—from source to
State Route 4002 bridge, West Branch

Water Attributes
Water—in the form of precipitation,
groundwater, and surface water—moves
freely between the atmosphere, land, and
underground by changing states of matter;
from liquid to solid or gas. This movement
is described as the hydrologic cycle.
In the hydrologic cycle, energy from
the sun evaporates water from plants, soils,
