This year I am considering a motion sensing light directed at my pond.
Anybody ever try this or know the conventional wisdom on its
effectiveness as a raccoon defense? I don't want to tackle the project
without at least some hope of success.

Lights won't frighten away a raccoon. I would opt for a motion activated
sprinkler (Scarecrow)

Agree with Joe. Motion light did nothing to stop the raccoon here in 2000,
but the motion activated sprinkler hasn't see them come back since I set it
up and I know they're around, they've been sighted. ~ jan
