Hey andrew,welcome to MntBuzz - Nevada.
Pm when you get out here. Not much to run during the low flow summer, except parts of the truckee. The american is close and boatable all year ( 2+ hr drive), the Carson runs in the spring (1+ hr drive). Northern CAli and Sothern Or are all about 6-8 hrs away and there are goods up there. A bit further to Central CAli, (Tuolemne), and to SoCal (Kern) etc.... I'm sure there's more.
Great skiing however when it snows!
more snow = more water
