Half Life 2's first real puzzle (Spoilers)

As I begin my first official trek through this classic series, I stumbled upon what seems like HL2's first real puzzle.
 
The puzzle occurred during the Route Kanal section and consisted of wandering around two large rooms until you found a semi-hidden valve (get it?).  Once the valve was released and the rooms were flooded you had to figure out how to access the final corridor.  The problem was, the water level wasn't quite high enough to reach the corridor by swimming.  Or was it?  After being stumped for maybe five minutes I swam straight down in that final room and saw this: 
 

 
Once I destroyed the cross bars with my trusty crowbar a few chunks of round wood (can't think of what they're called) floated to the surface.  I hopped onto the floating wood and jumped onto the ledge leading to the exit.  This was a simple, logical puzzle which showcased the advanced physics engine in Source.  I'm definitely excited by what's to come :) 
 
This is a short entry in a series of posts covering my experiences while playing through the Half Life series (starting with Half Life 2).

I got stuck on the same exact part! Half Life 2 is great though, welcome to GB!

Ya, I have no idea why the spoiler thing isn't working.  I just highlighted the text and selected the spoiler icon.  Weird.

I think chunks of round wood are called logs.
