Cold-weather springs and well

I've spotted a few points on my property that seem to leak water (pretty low flow springs) but only during the colder half of the year. The whole thing is wooded, so it's hard to be sure, but I think these are the key points of shallow valleys. I hope to increase and extend the flow as I apply permaculture principles to the land.

In the meantime, the county has a requirement for a well to build there. I'm wondering if near one of those cold-weather springs would make a good well? Is this a bad assumption?

Time it right so the inspection is in the wet season...

Does the County tell you where the well has to be installed?
That sounds strange to me.

I was told verbally that the requirements to build were -

Well, Septic, no mobile homes, 1000 sqft minimum*, meet IBC 2016 building codes.

*followup on the 1000 sqft - that is measured from above, continuous roof - it could be 400 sqft heated, 400 sqft carport, 200 sqft porch - as long as it's all one roof. My current draft is ~600 sqft heated, with the north wall bermed, on a mild south facing slope, outdoor cooking area to the west, and outdoor shower, natural swimming pool and hot tub to the east, south to be a large pond. Well would be just to the west of the pond at the key point, with a pump to supplement rainwater capture from various roofs when there's a drought. (In other words I want a well to meet the letter and spirit, but necessarily for a primary water source.)

I'll have to look up the wording of the regulations...

Find the water well database for your state and look at the well logs for neighboring properties.  These logs will also have minimal geological descriptions of the lithologies penetrated and the results of a short term yield test from the well.  You could also talk to a local well driller and see if they have any knowledge of your area, but remember the driller is in the business of drilling and current costs in my are $30/vertical foot, plus mobilization, pump installation and connection.  

Low yield springs that you described that appear only in the cold months are often the result of the drop in evapotranspiration from the forest as the vegetation goes dormant.  This allows some shallow water table rise and discharge along slopes or in nearby drainage features.  This is not a source you would want to use for drinking.  Most states have a minimum well depth requirement of 25 feet below ground surface and minimum setbacks from surface water features and septic system components.

A UV filter can do a lot... around me, the deep well water is always fairly gnarly; treatable but without expensive treatment undrinkable or nearly so; salts and metals.

The lucky houses have a good shallow well; my neighbours well is 10-12ft deep. Mine is about 18; I could dig no deeper as I hit a layer of wet gravel that really liked to slump and threatened to undermine and collapse the heavy clay above it...

These days most folks on the shallow wells have a UV setup, but many of the wells predate that option..
