BirdTrout
Birch Run, Pennsylvania
4.1 mapped river miles, draining 5 square miles, in the Brandywine Christina basin watershed. A USGS gauge stands in it, but its record is too short for a measured July mean, so what this page knows about its temperature is today's reading and PA DEP's classification of the water itself.
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 management tier on those reaches is Cold Water Fishes, Trout Stocking. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.
