Not sure what you consider a 'reasonable distance,' but, Loch Low-Minn quarry, in south Tennessee just stocked up with Paddlefish about a year ago...
We 'ran' into one at about 60 feet, in the middle of the quarry (less than a meter long, but they'll get there).
There's a good Powerpoint on the Loch Low-Minn site, that shows and talks about the Paddlefish "launch": LOCHLOWMINN MAIN PAGE
