I'll have to give that hatchery a call, they aren't much further a drive than where we currently get our trout from.

The spring is mostly under ground. Only during the spring and heavy rain falls does it actually surface. A few years ago, we took a back hoe and dug out a small hole in the ground where the spring runs. Water seeps out almost year round in that spot keeping the water in the hole fairly fresh. We did that to give the deer a place to get water as the next closest water source is over a 1/3 of a mile away.

I would say maybe 30 gallons per hour? The flow is pretty light. In the spring it is much stronger. Never measured the actual temperature, DO or pH of the water that comes out though. I have drank it with no ill affect and the taste is spectacular!

I may try to take pictures of the area I would like to put a pond in this spring and post them on here and get ideas if its a good spot to work with...
