Or... The camera is focused at infinity. The bug is within a few 10's of cms of the camera. The "light reflected off of the water" is actually an out-of-focus bug. > I think the streak is about 2 meters across and 160 meters long; he > thinks > 205 meters long, and so forth.

In any case, assuming that the object is distant and fast requires that the object move at hypersonic speed, producing shock waves and a considerable sonic boom (and perhaps a lot more light than we see here). A bug, close to the camera, moving at bug-speed, is still the simplest and most likely answer. I'll still vouch for the "It's just another bug hunt" answer.
