Best way to increase GPM from existing deep well | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

I have a 2.5 gpm deep (400’) well that I’d like to draw more from. It’s consistently delivered 2.5 for decades at 104’ (nearby river depth)
The two options I’m considering are some sort of fracing or an additional well. Concerned fracing might compromise existing well since it’s so low flow..

tnx
