Question

Bans Lake and Lake Roosevelt, what determines whether the word lake comes before or after the name?

Answer 1

Nothing, really. Although, generally, larger lakes have "lake" before the name (such as Lake Michigan). This isn't always the case, as some small lakes have "lake" at the front, and some large lakes have "lake" at the end (such as the Great Salt Lake).
