If you're wrong than that makes two of us. We cleared a creek bottom for our pond and the largest stumps were "saved" to line the creek channel for habitat purposes. I believe the natural wood structure is best and it will last a long tome submerged with no oxygen to aid in its decomposition. Some of the best lakes are flooded timber remaining for 40+ yrs on L.Hartwell and L. Russell on the Ga/Sc border. Aside from tannin releases, it just feels better fishing over natural structure (including rock piles) than pvc and waste material. With a creek fed pond with constant water flow I'm doubtful the tannins will negatively impact the fishery. IMHO.
