Thanks in advance for all the advice and recommendations that are posted on this forum. I recently subscribed to PB magazine and can't wait for the next issue to arrive. I bought some land a couple of years back that had a 1-2 acre pond already in place. I believe the pond is around 30 years old and it's about 25 feet at the deep end. During the rainy season the pond is full. After that and by end of summer / fall, the level will drop about 6-8 feet, afterwhich it seems to stabilize. Numerous trees, brush, etc. had been allowed to grow on the levee before I became owner of the pond. Based on previous advice I received from this forum, I removed anything growing on the levee that was smaller than 6" dia. at 4' trunk height (or was it 4" dia. at 6' height?!?!) and left the rest which includes some pretty good size pines and hickory (24-30" dia.)on the back side of the levee. I'm pretty sure (based on limb lengths) that drip lines & roots from the pines have already reached the water side of the levee. Based on previous posts, it seems that removing these larger trees is not an option. I'm currently considering / pricing the various sealing options including bentonite, liners, ees-13, etc. My main concerns: If I leave the trees in place, what affect will they have on the various treatments / sealers. Also, is it possible or feasible to just drill a well a few hundred feet back from the inlet side of the pond and utilize it during the drier periods to maintain water levels ? Thanks again to everyone. I enjoy reading the posts and learn from every one of them. Best Regards. Jim
