Last year a client had rip-rap added to his pond edges. It was placed from about water level down to about 3' water depth. The dump truck backed up close to the pond, and the excavator scooped it out of the dump bed. It was pretty easy to place in the pond, just shake the bucket a bit until it was a 2 rock thick layer and keep moving along the edge of the pond.
If using concrete, try and cut off all the wire mesh and rebar that is sticking out. Too many points to get impaled on, and the metal seems to attract lures.
Good point Scott - I will only accept rebar/mesh free concrete from my guys. So far they haven't broken the rule. I would not have the time or gumption to sledgehammer that rebar and would never add it to the pond for fear of someone slipping and impaling themselves. In hindsight, a little wouldn't be bad to catch some illegal treble hooks some guys insist on throwing, however.
