Local tips

Every boat needs a Grand Teton boat permit and an aquatic invasive species inspection before launching.
The lake is drawn down for irrigation, so late-season levels can close ramps; check NPS status first.
Water stays below 60 F even in summer and afternoon winds build fast; wear a life jacket.
