Please do. Would be glad to show you around to see if you could glean any ideas.
Here is an old thread on rock and gravel that might have some worthwhile information. rock lining
One other feature somewhat unique to my pond that I like is permanent boat moorings. We have an aluminum paddle boat for pleasure riding around the pond. We also fish from it sometimes. One disadvantage to such a boat is it sits high in the water which is very comfortable to fish from but as you are likely aware Kansas gets some wind sometimes.
Well the boat really sucks in wind as it gets blown around badly. My solution was to put in permanent moorings we simply hook up to. Some of my structure/cover involved concrete foundation chunks stacked up lincoln log style with a cedar tree in the middle. I tied a rope with small float to these in a number of locations around the pond. They serve two purposes. Boat mooring and a reminder where the structure is located. By having a number of these permanent moorings around the pond we simply hook up to one upwind to where we want to fish and let out rope to where we want to be. There are a couple areas I would like moorings but with no heavy structure to attach to. I have purchased some earth anchors to install moorings in a couple of these areas, but the installation would have been much more simple had I thouht of it before the pond filled.
If you want some moorings it would be simple to auger in some earth augers with ropes and floats attached in a dry pond bed. Then when the water filled they would be exactly where you want them. Many people would not see a benefit to this. But for some, depending on their BOW and the type of fishing and boat they plan to use, it might be worth considering.
Edit: Prior to the permanent moorings being installed I tried two different kinds of boat anchors. The first was not heavy or agressive enough and the boat just drug it around on the mud bottom. It is still on the bottom of the pond where it attached itself to some of my structure and could not be retrieved. I almost lost the second one the same way. That is when the idea of permanent moorings was hatched.
