When I built my big pond I did this - put down 300' of weed control fabric 4' wide - where it's centered on full pool - and then had 12 dump truck loads of riprap brought in and dumped in a pile. I then used a skid loader to move it where I wanted it - dumped some and placed a good bit by hand.

That was 10 years ago. Rocks are still there and still doing what I wanted - primary goal was erosion control, with a secondary 'hope' of keeping the muskrats off the pond dam. 100% successful with the erosion control and as far as I'm aware also with the muskrat control - I do indeed HAVE muskrats but so far they haven't built on the dam. Not sure how much of that is due to the rocks....but I'll take it.
