1. A skimmer for selective removal of objects floating on a surface of a stream, said skimmer comprising a float skimming line installed across the stream at an angle with respect to a flowing direction of the stream, said float skimming line having an upstream end and a downstream end and further comprising at least one elongated member extending in the flowing direction of the stream and downwardly from the surface of the stream to a bottom thereof, said elongated member having: an upper end being attached to said float skimming line at a location between the upstream and downstream ends of said float skimming line; and a lower end removably anchored to the bottom of the stream so that the upper end, and hence said float skimming line, can be pole-vaulted off the surface of the stream when an object of predetermined size and weight traveling downstream hits said float skimming line.
