Answer:

The mountain stream will be (i) colder, and (ii) faster moving and more turbulent than Old Man River. Both factors should maximize oxygen solubility.

Explanation:

Gas concentration in solution increases with decrease in temperature. In addition, a faster moving stream should reach equilibrium with gaseous oxygen more quickly.
