Ponderosa Pines Pond

I am interested in constructing a pond, but have a few questions. My ideal location is in the midst of ponderosa pines. I'm wondering if the pine needles and acidic soil will impact the maintenance of a natural pond. Are there special needs / precautions to take? I am priviledged to have a number of wildlife move through the property (deer, elk, pronghorn, porcupine, racoon, fox, turkeys, hawks, and owls). I am concerned about the presence of standing water and the potential for leptospirosis to be introduced to the water by the wildlife. I have a significant investment in Gordon Setter hunting / show dogs. Are there precautions that can be taken to prevent this (extensive fencing is not an option). Also, I'm concerned about the extent to which a body of water could attract migratory birds that could carry avian flu. How do I deal with / prevent that? I have a significant investment in chicken and duck flock.

What qualities  do you want from a pond?
Attracting wildlife seems to be a negative for you,and  you are concerned with the influence of the surrounding trees.
Maybe a cistern would serve you better?
As for the idea of pine needles contributing to the acidification of the soil (and bu extension water)this idea  has been contested via lab testing which found no such influance.

I'm not opposed to attracting wildlife, I'm just concerned about the potention for leptospirosis contamination and wondering if there is a way to mitigate / remediate.
I'd be interested in swimming in and relaxing around the water.

The idea that pine needles are acidic is a myth. On the tree they are slightly acidic. Once they fall off, they are no longer acidic and will not change the pH of your pond.
