A neighbor just told me last night his gelding is "still hanging on". Asked how old he is, and he said, "Oh, I know he's over 30!" Holy cow, I know ponies can get that old, but this is a horse. Glad your Pappy made it through that horrendous winter. It's really hard on all animals, especially the old ones.
Colleen, if there was a spring, I could not use it since the land is totally flat around here. There are springs in the ground ... well I guess that's true everywhere. The ground water in my area is very near the surface, and there is lots of it, so that's why my wells come back so quickly. Also, it's a bad thing, because part of my barn had been dug down about 2' (before I bought the place) and that area has standing water in it unless a drought. I need to fill it back in with dirt, just one of those projects have not gotten to yet. It's like someone ran a hose in there all the time, but no water runs in there, it's just what soaks into the ground nearby, comes out in the barn area. Other area right next to it doesn't have that happen, because it is backfilled. Stupid people before me went in and dug out huge areas really deep, never finished, and never filled it back in.
Where I lived when I was married, we had a great spring, though. It was in the hillside, and probably 30' wide. That whole area stayed wet year round. There was an old trough at the bottom, and a pipe into the hill. Used it to water cattle many years ago. We built our pond and that area is now filled with water. Always wondered if that spring still ran, and if it would help fish spawn, with running water. Probably the pressure from the pond water pushed at the spring and stopped it's flow, though. Not sure how that would work.
