Pennsylvania Wild Trout Maps

Available as an advanced Web Map.  Many of the underlying datasets may also be downloaded as KMZs via the PA Downloads Link in the Resources Menu!

Pennsylvania has some of the best documented wild trout streams in the NE US.  The Pennsylvania Fish and Boating Commission ("PAFBC") publishes comprehensive lists of wild trout streams and a number of useful mapping databases that we've made available on our state-of-the-art web map.

Each of these datasets is described in the pages you can find in the PA Resources Menu in the sidebar.  They include:

  • Trout Natural Reproduction - the master list of where the PAFBC has found wild trout in fish surveys. 
  • Class A Streams - the streams with the most trout per hectare in the state (30-40kg, depending on species). 
  • Class B Streams - this list isn't officially published, but we've extracted a dataset based on careful analysis of a map published in 2010.  These streams support a minimum of 20kg/hectare, though many fish quite well.
  • Wilderness Streams - these are almost all Brook Trout streams found in wilderness settings.  Streams can be rated Class A, B, or C. 
  • Class B-D Overlay (KMZ only) - this is based a map published in the PAFBCs 2010-14 strategic plan.  In January, 2014 we re-issued this popular overlay with an improved version that's much more accurate and easier to interpret.

In addition to these datasets, the TU CSI basin habitat data (shown in the image) is available for the state, and the PA DEP publishes water quality data.  All can be downloaded through this site.

You also have a choice about how you want to interact with the data.  You can deal with it the "old fashioned way" by using the lists (though the search feature of a PDF makes even that less painful than it used to be).  Highly recommended is that you set up your own "Wild Trout Workstation" using the "National Map" (a web viewer) and "Google Earth"  (a free application you download on the Internet).  Finally, as sort of a middle ground, you can use the slick, new PAFBC Interactive County Guides via your web browser.  However, it only gives you information about Class A streams. provides the most extensive collection of information about where and how to locate wild trout streams. All for free.
