outflow
Not my area of expertise, but I think this is the outflow river, as opposed to the tributaries ('affluents'): the rivers flowing in and out of the lake.

Note from asker:
| Thank you Anne-Marie Laliberte. This is very interesting, but I think it refers to stagnant water: https://en.wikipedia.org/wiki/Emissary_(hydraulics), or it may be archaic. Erring on the side of caution, therefore, I've decided that, here (for a river flowing out of a lake), 'outlet' is better. |
Discussion
You appear to have misses a bracket (before [river}) that is very important.
