Hi guys: I have a 3/4 a. new, muddy pond with zero structure except for a large rock ledge slmack in the mniddle of the pond. Basin is about 12-14 with most of the depth at about 7-8 feet. I am beginning to add structure this weekend. I am putting 6-8 10 ft. cedar trees in cemented buckets,wired together and standing upright. I have 3-5 20 foot cedars to lay on their sides with cinder blocks to keep them down. In the shallow end I have spread 15 tons of creek gravel, and plan to put wood pallets weighted down with large boulders, in that area. I also have about 75-80 basketball (or larger sized rocks from the property to dump (hopefully strategically) into the pond for addl structure. Question: Should I drop a large oak into the pond or will the tannin acid be too much for it to handle? Any other suggestions will be greatly appreiated. I plan to begin stocking this fall, but will put some baitfish in shortly. I am shooting for a bg, red ear, lmb pond.
