Sixmile Run, Pennsylvania

50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.

The nearest live reading

The nearest gauge is 15.3 miles away, at Wb Susquehanna River At Karthaus, Pa — not a reading of this water, but of what the region is doing today.

Thermal classification

PA DEP's classification of this water, reach by reach. A class, not a temperature — no July mean, because none was measured here.

Reach Typed miles Band PA DEP type
RM 7.5–0.0 11.8 cold —

PA DEP has classified 11.8 of the 11.8 miles NHD carries for this stream — 100% of it. Every typed reach carries the same class, cold. The untyped reaches are not warm water — they are water PA DEP's inventory does not reach, and the mile ranges above span only the reaches it does.

PA DEP classification

PA DEP classifies this water as Cold Water Fishes. The management tier on those reaches is Cold Water Fishes. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.

Public land on the river

2 units of public or open-access land touch this river, 188,687 acres in total. Acreage is the whole unit, not the part beside the water.

Species

Tributaries and watershed

1 named stream meets this one. Confluence miles are above the mouth; the longest twelve are listed.

Sixmile Run sits in HUC 8 02050201, the Upper West Branch Susquehanna basin, and drains 17 square miles, Strahler order 3 at the mouth. 26 NHD reaches carry the name for 11.8 miles in total — more than the 7.5 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
