CTPRES:
We are in the excavating business, among other things, - - - - - hire someone who builds ponds and knows what he is doing!!!!!!! Don't try it on your own!!!!!!! Even without knowing much about your situation, there are many things to consider, design of primary spillway, secondary spillway, compaction, regulatory requirements, safety (moving that much material with that type of equipment takes time, time results in fatigue, fatigue may lead to mistakes), etc., etc.
Our farm is in Ohio, and it has to be easier to build a pond in Texas than in the hill country of Ohio. However, I find it amazing that people talk about building a pond for a few thousand dollars and in a few days. That is probably possible in the ideal location, but it isn't the case in instances. In fact, I often wonder if those people have ever built a pond. Or, did the build a mud hole?
For example, last year I built a pond on my farm with OUR employees and OUR equipment (750 JD dozer, 850 JD dozer, 160 JD excavator and a BOMAG for compaction). We had to construct a deep pond due to the lay of the land (ended up 17-18 feet deep) and it wasn't a dug pond like you would probably have. It was an impoundment with a dam. Quality fishing was important to us so we built structure and did a few extras. In the end, the pond was a little over an acre in size, we moved the 750 dozer and the excavator in on August 9. We took the 850 over two weeks later after the grub work and key were well under way. I pulled the equipment out the first week of November with a total cost of $65,000 - - - - and keep in mind that we owned the equipment and paid the employees thier regular hourly rate. In the end, we had approximately $ 30,000 in diesel fuel - - - the 850 alone burns 100 gallons of fuel a day.
I would think two or three times before I started to build any pond with a compact tractor. Just my two cents.
