All 129 conservation populations and their occupied streams — filter, sort, and map the data on a live topographic basemap. Bakevich, Paggen & Felt (2019).

📍 How the markers & stream traces are placed
Markers are geocoded to the named stream via OpenStreetMap and the USGS GNIS gazetteer — each solid dot sits on (or at the mouth of) its actual creek. A minority of small tributaries aren't in either gazetteer; those show as faded/dashed dots placed beside a mapped neighbour in the same drainage. Points mark the stream, not the exact occupied reach. Colour = population density (highest fish/mi among its streams). Two independent stream overlays in the layer switcher (top-right): the blue RGCT stream traces = each population's creeks — the full USGS NHD centreline for every named creek (click for its name; the population occupies part of it — see the reach's Km), plus the small forks and tributaries that are unnamed in the national hydrography data, traced from the RGCT Conservation Portfolio (Trout Unlimited) and shown the same way (their popup names the population's reach). Red NM Special Trout Waters = NMDGF designated reaches. Toggle either; click a stream for details.
📚 Sources & data notes
Compiled from the appendices of Range-Wide Status of Rio Grande Cutthroat Trout (Oncorhynchus clarkii virginalis): 2016 — Bakevich, Paggen & Felt, 2019, NM Dept. of Game & Fish and Colorado Parks & Wildlife. Persistence from the Zeigler et al. Bayesian network (Appendix B). Named stream courses from USGS NHD; occupied-habitat reaches (incl. unnamed forks) from the RGCT Conservation Portfolio (Trout Unlimited). Basemaps: Mapbox, OpenTopoMap (CC-BY-SA) & Esri. Non-native codes: BRK = brook trout, BRN = brown trout, RBT = rainbow trout, WS = white sucker.
