Rather than try to fiddle with elevations on Google Earth (and not having a hard copy topographic map covering the Lagoon with Many Names - hereafter LMN)  I went looking for an online topographic map.  The best I could come up with was this one from Geoscience Australia.  Astonishingly it uses the 'alternate name of Tarago Lagoon!  Even more astonishingly the contours are in feet, rather than metres - unless there has been some astonishing orogeny in recent days!

​  

​2500m is 76​2 m and 2250 feet is 685m.  From looking at the contours, the country to the ENE of LMN is closer to 762 m and thus there is unlikely to be be flow from the lagoon that way.  Possibilities are going NW towards a string of lagoons South of Breadalbane - but I think there is a low ridge to the North of the Highway  - or, my bet,  SW towards Lake George.
