This is taken from the user Mookiebone’s YouTube description:

I shot this video (with cellphone) of SOMETHING in the lake at Oakledge Park on Sunday (05/31/09) early am (0530 or so). I don’t know what the eff it is but it’s definitely not normal…Was anyone else out and about around Oakledge on Sunday just after sunrise?

No one is stating that this is the so-called “Champ” creature from lake Champlain, but the camera man states that the creature swimming is not something he would consider a “normal” animal to the location.

Many people assume this is a moose or deer swimming across the lake, others say it’s just an otter caught on video.
Cryptomundo has a post which compares the video in question with a myriad of other videos of animals swimming.

What is this swimming animal that was captured on lake Champlain?
