Hi,
Id love to setup a scarecrow sprinkler to keep Herons, cats and my dog
away from my pond. I dont want to have garden hose running acrosss
the yard, the pond is quite a ways away. Any easy way to use my
exisitng pump, that is feeding my waterfall, to push water to the
scarecrow? Any thoughts?

If the pump is powerful enough, sure. City water supplies generally pump an
minimum of 70psi, iirc. A well system 20-40, but most pond pumps will
produce nothing close. I suspect you'll just get a little trickle out of
the Scarecrow if you just tee off the waterfall line (noting that the path
of least resistance is still going to be the open outlet to the waterfall).
