what could be more typical for logging steam locos, as taking water from streams or ponds. Many logging locos were equipped with syphons to lift water from natural sources into the tender tank.
For my 5″-gauge Shay, I had such feature on my wishlist for a very long time. I spend two attempts in building one, but without sucess. Finally, I found a ready-to-use syphon at Shapeways. This one works great.
