Thanks to all for your wisdom and replies. I have to agree that water is going to be a huge concern in future.

Not sure if this helps the discussion, hard to get a sense of the topography from this, I know. A hurdle to overcome is getting permits from the rural municipality for outbuildings like barns, let alone ponds. I can certainly relate to Holzer!
We are Zone 3, 3640 ft altitude. The climate is greatly influenced by the elevation and proximity to the Rocky Mountains. Our winters can be uncomfortably cold; but warm, dry Chinook winds routinely blow into the city from over the mountains during the winter months, and can raise the winter temperature by up to 27 °F in just a few hours, and may last several days. It's a place of extremes, and temperatures can range anywhere from a record low of −49.0 °F in 1893 to a record high of 97.0 °F in 1919. Temperatures fall below −22 °F on about five days per year, though extreme cold spells usually do not last very long. Average daytime high temperatures in range from 75 °F in late July to 27 °F in mid-January.
Due to high elevation and aridity, summer evenings can be very cool. The average summer minimum temperature drops to 46 °F but summer daytime temperatures exceed 84 °F anytime in June, July and August, and occasionally as late as September or as early as May. With an average relative humidity of 55% in the winter and 45% in the summer we have a dry climate and humidity is rarely a factor during summer.
We are among the sunniest cities in Canada, with 2,405 hours of annual sunshine, with an average rainfall of 16.24 in of precipitation annually, with 12.62 in of that occurring in the form of rain, and 49.9 in as snow. Most of the precipitation occurs from May to August, with June averaging the most monthly rainfall. Droughts are not uncommon and may occur at any time of the year, lasting sometimes for months or even several years. We've been looking a long time for a location that provides land, water, buildings/barn. No one around us is much concerned about water (at this point!) and think we are crazy for insisting on this.
