Mammoth Lakes campgrounds?

[Mase]

The reservation sites say they close in mid September, except for Twin Lakes. Are those solid close dates or will the campgrounds be open until the first snow?

I want to go up there one more time this season but I may not make it up there until the end of this month or beginning of October.

Does fishing season close up in mammoth? Dose that have anything to do with the campgrounds closing? I know at the owens river Fish and Game have signs up that tell you the dates the fishing season starts and ends. Is it the same for the surrounding lakes?
