I had a little too much time in my class the other day (the history of Lebanon doesn't do much for me). I was trying to think of all the existing water tanks on the narrow gauge circle. I am not sure of the accuracy, but I will list what I could think of off the top of my head, and the rest of you guys can fill in the blanks.
Silverton Branch---Needleton & Hermosa
Farmington Branch---Bondad
Dgo to Chama---Navajo, Gato,La Boca (@ Sundown and Southern), Chama
Chama to Antonito---Cresco, Los Pinos, Osier, Lava (Antonito's tank)
Chili Line---Embudo
Salida to Montrose---Mears Jct. (@ Gunnison)
R.G.S. Trout Lake, Rico, East Mancos
These were what I could think of off the top of my head, next time I'll try counting depots.
