Sounds good, but keep it simple. Put a shallow, wide trough over the spring, line it with some clean stone or a sturdy tarp so the water doesn’t just wash away. Add a few gravel layers at the bottom to keep debris out. Then channel it through a small pipe or hose into a storage barrel that’s buried just enough to stay cool. Use a basic flap valve to control flow, and keep everything hand‑tight. No fancy gadgets—just solid wood or metal, a tight seal, and a good eye on the slope. That’ll hold up when the weather gets rough.
