Yes, I realize that folks in different circumstances have different points of view, and therefore different philosophies. Myself I'm a realist, after passing my 50th birthday I realized that I'd best have a realistic outlook towards what I'd be capable of in the future, and also of what my needs would be. Even now I have no use for about 90 % of what crops I produce, so what I can't use I try to give away, not always easy. Also being bent on gardening I'd not choose a spot where water was a major problem, or I'd cut way down on how much gardening, or I'd simply find different endeavers for investing my time and energies that don't rely on water, perhaps take up sculpting and knitting. But it's been rare that I needed to carry water because of dry spell, and only because I put in some new saplings too far for dragging a hose. Where I live as a rule there is too much water, there are periods when it is too wet to mow without the tractor making tire ruts, so I don't mow the wet areas until the ground drys out.
During dry spells that stream can shrink down to a damp spot although it mostly runs, but during heavy rains and from snow melt it can easily become a raging torrent overflowing its banks and then erosion becomes a problem... last year I had to have an excavator come in to reshape and riprap that stream. There is such a thing as too much water.
The little trickle running alongside my garden is spring fed so it runs all year, in fact it continues out around my barn, crosses through woods and fields, and fills my pond. During dry perids there is no visable water flow but it's always damp and were I to dig down a few inches with a shovel the hole would fill right up, the deer and other critters scrape small depressions and get water that way.
