No, this is not a waterfall of CW signals, but..
On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0 × 10−21.

Very nice and clean results just as is predicted by theories and simulations.
Go forward to 31m:11s.
