My memory was jogged by another thread, to a day on a clear river - I can't remember which - when I saw a patch of gravel slightly coarse than the rest, and a few of the stones were dancing! Not trundling off downstream, just lifting a bit and settling back down. The only cause I've ever been able to think of for this is the presence of a tiny underwater spring.
This begs several questions!
- Are they common?
- Do they bring oxygenated or deoxygenated water ? And if it depends on which kind of aquifer, how so?
- Cave temperature=beer cellar temp=about 12 celcius; I assume most springs will run at this , but are any warmer ones known? (Bath springs to mind as a likely place...)
- How does one find them?
-Do hydrologists have this info mapped annd squirrelled away somewhere? If so, how do we, the public, get to see?
-I imagine they'd be worth seeking out in the winter, but does anyone know of a spring exerting an influence on fishing in the summer?
