I'm not sure if you have to rip rap everthing
Dave. I you want to be conservative you could only rip rap the sides of the pond that get the most wind, and the levee side that is at most risk by rodent damage.

It can definitely get expensive. In my area limestone is fairly cheap, but I don't care for the way it looks. I prefer landscaping stone but it is salty in price to buy and haul.

I recently found a massive pile of field stone just down the road from a waterline project, but unfortunately totalled my van pulling a load of it. Apparently I overloaded the trailer and it started fish tailing on me and fliped my van on its side. The dog and I had to climb out of the windshield to get out. So respect those trailers and don't overload them!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
