A stocking regime based sole on put and take is IMO the most realistic. Consider stocking the largest CC you can obtain. Generally you can find 12" fish rather easily and not that expensive. You could stock a hundred or so every spring or when most readily available. In the fall, probably early to mid Oct, you can stock trout. If you feed you can expect good growth rates on your CC. Fishing for the trout should be good through the winter. If the pond dries up and causes fish kill, you haven't lost a long term fishery as mentioned. I would say HSB could be an excellent option as well however they are illegal to stock in VA.
