For years, the PA Fish and Boat Commission (“PAFBC”) has published a list called “Trout Natural Reproduction”. This is the master list of streams where the PAFBC has surveyed naturally reproducing trout. Note that the actual universe of wild trout streams in the state is much larger than this, but since resources to survey new streams are limited, the list grows slowly.
In recent years, the PAFBC has helpfully published shapefiles and KMLs of this data so it can be mapped on Google Earth, the National Map, and other computerized mapping software.
As WildTroutStreams’ tools have improved, we’ve tried to add value to the basic PAFBC offerings. Here we’ve merged the complete 2013 PAFBC list (which provides no quality information of any kind) with water quality classifications from the PA Department of Environmental Protection’s (“PADEP’s”) CH93 list.
This designations are visually-coded in the KMZ as follows: EV (exceptional Value – light pink, thick lines ), HQ (high quality cold water – medium pink, medium lines), CWF (cold water fishes – dark pink, thin lines), TSF (trout stocking water, i.e. “coolwater” – mauve, thin lines ), and WWF (warmwater – purple, thin lines).
These PADEP categories relate to the PAFBC’s in that, by rule, all Class A trout streams are designated either EV or HQ, and Wilderness Streams are designated EV. The rules don’t work in the other direction (all EV and HQ streams are NOT necessarily Class A or Wilderness) though one would expect that the EV and HQ streams to contain better habitat than the CWF and lower classified streams. So having this information available is invaluable in trying to sort out streams which aren’t otherwise designated.
Use this layer in combination with the other datasets you can download from this site: Class A, Class B, and the TU CSI basin data. In combination they provide an extraordinary level of detail about Wild Trout streams in PA that is matched in few other states.
