Check the depths of the ponds that you want to rejuvenate. Use a boat and a weighted rope or, if shallow enough, a pole of some type. Or just go swiming and bobbing up and down...if your into swimming in ponds. A shallow pond will ussually have vegitation troubles which can lead to constant upkeep to maintain it to your liking. Once you know the depths across the ponds, you may find that it is time to have them dug out or the dam heightened, or both.

If this kind of approach is not in your budget, you could apply hebicides on a yearly basis to some areas of the pond/s to keep some fishing holes open for the youngster. Lily pads are a favorite weed of mine to fish through with weedless top water frogs and weedless rubber worms.

With a set-up like that, I would consider making the middle pond a FHM, Scud, PK shrimp, & crawdad forage pond and concentrate on improving the lower pond first. This might mean killing the fish in the top two ponds first before stocking forage, but it could create one great pond at the bottom of the hill. The first pond would just be a settling pond to continue reducing the silting in of the others while the middle pond grew forage that would wash down to the "fishing pond" (or you could trap and siene forage and transfer to the fishing pond). That would be one cool set-up!
