Exclusive 0610_erin_brockovich-ellis_mug_shotErin Brockovich”s new mug shot is pretty rough and pretty shocking … but that”s what you get when you operate a boat wasted … allegedly.

our sources broke the story  … Brockovich was popped over the weekend for operating a boat under the influence.

A Nevada game warden spotted Brockovich struggling to dock her vessel at Lake Mead … her BAC was nearly double the .08 legal limit.

Brockovich apologized this morning … insisting she didn”t endanger anyone because she wasn”t boating in open waters — just moving the boat “within its own slip.”

“That being said, I take drunk driving very seriously, this was clearly a big mistake, I know better and I am very sorry,” she added.  

We”re told Brockovich is free on bail after briefly docking at the Clark County Detention Center.
