I found the flag on Wikipedia, but I cannot find any reliable sources verifying that it is actually used or officially adopted by somebody. So take it with a pinch of salt.
Anyway, there is an official flag of the Evenk Autonomous Okrug looking like this:

But I like the flag in the main image better, so that's why its the main image. And even if it might not be true, it is still a nice flag.
FOTW also lists this possible flag, that I'm not as impressed by:
