Thanks for that info, Bernie. I guess there's not much point in
trying to record that for others to listen to; perhaps a hydro AM
receiver would be more appropriate?

There is also the problem of fishing, as seen here:

or

Education of local fishermen may be an answer to that part of the
problem, but it probably won't happen fast enough to save the
remaining dolphins in Nepal, at least.
The run-off problem is interesting. While the polar caps are losing
surface area due to global warming/climate change, some parts of the
Himalaya are experiencing the coldest winters in 50 years or more,
resulting in less icemelt which, in turn, affects all life downstream
in one way or another...
