2,991 miles of mapped stream across 1,912 square miles of drainage in Berks, Montgomery, Schuylkill, Chester, Bucks, Lehigh, Lebanon, Philadelphia counties, in 205 named streams. Pennsylvania designates 992 of those miles as trout water, on 155 streams. The 11 mainstem gauges with a July record read between 66.7 and 81.3°F in July.
Open in BirdTrout50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands the app paints. On this map the colour is PA DEP's own classification of the stream, not a measurement, except at the gauge dots, which read live. Grey is water PA DEP has not typed.
HUC8 02040203 in the USGS Watershed Boundary Dataset. Every figure below adds up the river pages in this basin — same records, one basin at a time.
Pennsylvania publishes no thermal class. What PA DEP publishes is a Chapter 93 designated use — Cold Water Fishes, Trout Stocking, Warm Water Fishes and the rest — which names the fishery a stream is protected for. It is the closest any agency here comes to a temperature without being one, and docs/pa-thermal-fit.md is where the distinction is measured rather than asserted. It covers 90% of this basin's stream miles (2707.2 of 2,991); the rest is untyped and is drawn grey on the map above.
1009.3 of the 2707.2 typed miles in this basin — 37% — are cold or cold-transitional water. The dominant class is cool.
All 205 of them, longest first. 23 have a page of their own and are linked; the rest are in the app. The class column is PA DEP's designation of that stream. "Now" is the live USGS reading where a gauge stands in that stream.
