Yes, I know, I live a mile away from this big, beautiful lake.
How could I have a water problem?

First: Heron Lake is a man made lake. It's proper name is Heron Reservoir - so named after an engineer from the early 1900s, Kenneth A. Heron, who was said to have realized that water could be 'tanked' and held from the wetter areas of the north, to help the arid regions of the south. Heron Dam, finished about 1971, is what creates this beautiful, 5,900 acre lake. The key word in the sentence above is "arid". Heron Reservoir / Lake is located in the High Mountain (arid) Desert of New Mexico. This lake is primarily filled by snow melt from the north. Our lake / reservoir feeds into several others many miles to the south. Ranchers and Farmers buy allotments of water, from these reservoirs, so they don't deplete the ground water tables.
Second: On our property we have a well. The water is nasty, smelling strongly of sulfur, and is filled with iron. The water is filtered to the house and one stop is a water softener that uses water softener salts. From the water softener is connected the outdoor hose. Beyond that is a reverse osmosis system to provide drinking water. So - what happens to plants when you water them with salt water?
The water, directly from the well, needs to out gas before it's used. At first I had wild ideas that involved buying storage tanks to out gas - and rain water catchment systems. Both ideas were very costly and not practical, just to build a Mountain Garden.
Then a little while ago I had an idea. Instead of trying to build something 'new' why not use something 'old' that already works (duh)? Around this area Rangers and Farmers build great systems of water holding that they call 'tanks'. Many of these connected by little streams to move the water where they want it. They look like beautiful little ponds to me. These are filled with their allotment of water, rain and snow water, and in some cases well water.
I need to build something like this - on a MUCH smaller scale. A series of little (but deep), connected ponds would not only out gas the well water, but catch rain and snow. Planting around the ponds and little connecting streams would allow me to water the garden by putting a hose in an upper pond - using the natural grade of the land (which until this idea I cursed - now I realize my blessing) to move the water through the entire garden area - without a pump!
Another advantage is that the dirt that comes out of a pond area - to make it - can be moved to an area I want to level out. So now all I have to figure out is how one 54 year old woman, a wheelbarrow, and a shovel are going to get this done, ha ha.
