In the Hobbit by J.R.R Tolkien, what would be a short but descriptive summary of the Men of the Lake.

The Lake-men are mostly descendents of the people of Dale,
the land next to the Lonely Mountain.  When Smaug first took over the mountain, the
people fled and many, like Bard who is a descendant of Girion of Dale, established
themselves at Lake-town.  The Lake-men have an established, prosperous trade system with
the elves of Mirkwood. They use the river to transport and receive goods in barrels to
and from the Elven-king.

When the dwarves first arrive at
Lake-town, most of the Lake-men are excited about the possibility of restoring the
dwarven King under the Mountain.  They celebrate Thorin's return and sing many of the
old songs as well as create some new ones.  Many of the Lake-men feel that Thorin's
return will bring prosperity and wealth back to the valley and
town.
