Theme Day -- "numbers"

It's the first of the month again, and that means theme day on the one hundred and...... well a bunch of City Daily Photo sites. This month's theme for April 1 (April Fools' Day) is "numbers." The photo above, taken at the Bonnet Carre' Spillway shows the height of the Mississippi River.

The river has been slowly going down (in fact this photo was from last week -- the height is probably a few inches lower today. The spillway let about 10 percent of the river water take a short cut to the Gulf and go around New Orleans -- not so much to lower the level as to slow the flow through New Orleans and keep levees from being washed away.

By the time the river gets to New Orleans, it has fallen about 4 feet o 16.5 or something like that (changes daily).

One little known fact about the Mississippi River is that the last natural tributary to the Mississippi is Thompson Creek just north of Baton Rouge. The river from there to the Gulf (about 150 miles) is basically a flowing lake.

You get extra points if you name the only other natural tributary to the Mississippi in Louisiana -- hint, it is upstream from Thompson Creek and is a bayou.

Enough of all that -- here are some of the other City Daily Photo blogs that are celebrating theme day today. Browse around. You'll find some really creative stuff here.
