Yeah I know what you mean, it feels like I'm on a lake in MN with all the trees, really pretty.
This is over 40 years old because my wife's grandma remembered fishing there before so I can't imagine how much stuff is down there. I wondered about draining it and getting some of that crap out. The thought of draining all the water makes me cringe though. Especially since I don't even know how the water gets there.
If you don't mind me asking, how much did that cost you?
The price is not that simple to explain. In addition to cutting the dam, draining, and pumping it down twice (rain storm intervened once), I had the creek re-routed around the pond and deepened, pond mucked out and expanded to 3 times the original size...12' on the deep end tapering up to 4' on the shallow end. Had to hire a dump truck to move soil to other parts of our property. The D4 dozer was $85/hr, the excavator (hoe) was $75/ hr, the dump truck was $55/hr. The whole project probably took 70-80 hrs, but not all 3 pieces of equipment were utilized simultaneously. When mucking, the dozer and the hoe were used. Because of the rain and re pumping empty, mucking and pushing that stuff out of the way took the better part of 2 days. Not a straight up answer, but neither was my project...I hope this helps.
