Lower Susquehanna River Watershed, Pennsylvania

4,191 miles of mapped stream across 2,486 square miles of drainage in Lancaster, York, Adams, Chester, Lebanon, Berks counties, in 257 named streams. Pennsylvania designates 724 of those miles as trout water, on 118 streams. The 11 mainstem gauges with a July record read between 63.2 and 82.5°F in July.

Water temperature — the colour of every stream in the basin

50°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.

Cold, cool and warm water

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 91% of this basin's stream miles (3803.0 of 4,191); the rest is untyped and is drawn grey on the map above.

773.0 of the 3803.0 typed miles in this basin — 20% — are cold or cold-transitional water. The dominant class is warm.

Every named stream in the basin

All 257 of them, longest first. 14 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.
