I'm glad you are not the pilot on my air trips. When at the lake get some actual depth measurements. Go to this link and measure the size of the pond. We need to know the acres.
http://www.acme.com/planimeter/Buy some minnow traps and bait them with bread and or cat/dog food. Find out what the small "minnows" are. "There are yellow perch and white suckers currently with small minnow sized fish that sit on on the bottom in shallow water around the banks."
Suckers do not spawn in a pond; they are stream spawners. Are there small suckers and is the creek connected to the pond???. Use the minnow traps to check what fish are in the adjacent creek. Your uncle's may know of other local creeks or beaver ponds to trap to collect your own minnow broodstock as forage fish. You just need to know which ones to keep and restock that will spawn in the pond. We can help with that info.
IMO don't focus on trying to get trout to spawn. Consider them put and take. Stocker trout are pretty cheap and you would only need to add $50-$110 (6"-10") periodically to keep a good trout fishery going in that pond. Crashing your RC plane probably cost more than $50 for fixes. A few predators in that pond will make it into a very good fishery with the clear water situation especially if you install an automatic feed and use trout food. Imlay City fish farm should have pellet trained perch and maybe a few other species. A few walleye (4-8/ac initially) would help thin out the smaller perch. Walleye will not spawn which is good so you don't get too many predators that stunt to be slow growing. With winter kill you may need to periodically add more walleye & trout. SMB will reproduce to possibly overeat the forage fish (YP&minnows). You don't want that to happen. Adding fish is always easier than getting too many of them out.
