Conversations with concrete

Just because you lead a donkey to water …

Doesn’t mean you can make it drink.

This above hydrograph displays the actual flow rates at the S-333, as measured by the US Army Corps of Engineers (via their Daily Report).  The structure has not been flowing since the beginning of the month, despite water levels at G-3273 being at suitable levels for doing so.  Side note: The photo of flowing water at the S-333 was taken in November 2010.  Can you see on the hydrograph above that the flow rate was around 200-300 cfs? 

The same applies with the hydrograph that governs flows at the S-333 water control structure. The G-3273 hydrograph suggest that the gates should be open, but word from the field is that it isn’t flowing a drop.

Or, at least, that’s what the Corps of Engineer’s Daily Report reads.

Hydrographs, you see, are not dictatorial …

Rather, they provide general guidance.

Hydrographs add meaning
to what would otherwise
be concrete and steel.

That being said, I didn’t go out and check the flow rate in the field, at least not recently. To do that for every structure would of course be impossible, too. Of course, on any given day when I’m out at any given structure I try to remember to bring my hydrographs along. It’s really the only way to see what’s going on.

Otherwise you’re just looking at concrete.
