Hi all, and thanks in advance for any advice you can give to this pond newbie with zero experience.\n\nFirst off, I'm hoping I can get some advice even though I'm not trying for a koi or goldfish pond. I don't even care about anything decorative; I'm looking for something practical that I can stock with trout or catfish for meat as well as provide a habitat for some egg-laying ducks for my homestead.\n\nWe live in the mountains of northern New Mexico at around 7,000 feet. Temperatures are fairly moderate year round (usually ranges from about 20 to 80 degrees), but the climate here is very dry, and we don't get much rain (maybe around 10-12 inches total precipitation on an average year, but some years are droughts). We rely only on rainwater catchment for our home, and thus are very limited in the amount of water we can waste.\n\nWould a pond be viable for our situation? Not sure what size I want, maybe enough for 100 pounds of fish a year plus a dozen ducks max. I'm worried about the amount of water we might lose to evaporation, and I'm also wondering if there's any way to filter the dirty water so that we won't have to replace it (and save ourselves some water that way). I know filtering ponds is the norm, but I'm hoping I can go above and beyond the average filter to remove most if not all nitrates and ammonia from the water and just recirculate for the most part. I could potentially dig a well, but that's a last resort for me. Thanks so much for any advice!
