Surprisingly, I expected the Corp of Engineers to ban it on their lakes (like the flying tube), but they say "(g) Water skis, parasails, ski-kites and similar devices are permitted in nonrestricted areas except that
they may not be used in a careless, negligent, or reckless manner so as to endanger any person, property or environmental feature."
Rivers around here are too narrow, but some lakes would be ok, just have to pay attention to the wind.
