WildTroutStreams.com provides online mapping data, useful documents, and other resources for finding wild trout streams in the lower-48 states. State-specific data is found under this “Streams” tab, while “Native Trout” data, which is species-specific and tends to be regional, is described under the “Natives” tab. We started by focusing on the Eastern US back in 2006, added western coverage (with an emphasis on native trout) in 2011, and in late 2013, have now expanded to the midwest.
At this point all CONUS states that support a significant wild trout resource (and a few that have minimal resources) are covered.
All data is from public-domain sources (though some is pretty obscure). We add value by converting data about trout streams to user-friendly formats (such as KML for use in Google Earth and the National Map) from professional formats such as GIS and relational databases. We also pluck useful, public-domain documents about wild trout streams from the bowels of obscure websites and make them readily accessible here. A red dot on the map indicates we provide data for trout streams in that state. In most states we have both state-level datasets and “native” datasets that describe species that live in those states (brook trout in the east, and a variety of species out west – see the “Natives” tab).
