“New and improved” Lake Chart

How big is Lake Okeechobee?

Answer: Too big to see all at once.

And I’m not talking about its water, but rather its data. Inflows, rainfall, outflows, stage levels and budget. It’s just too much information to fit into one graph …

Or is it?

At the top of the page is a new and improved hydrograph that sort of tries, with one big caveat –

It only goes back 3 years (to 2008).


To go back deeper (years and even decades) is where I recommend using a hydrographic calendar instead.

The one below shows Lake stage from 1940 to August 2010 presented in the same style in which you read the words on the page of a book: years run from top to bottom and months from left to right.

Granted, it’s not Shakespeare,

But that’s a lot of data crammed on one page.

Similar style graphs are available for Lake inflows via the Kissimmee River and estuary outflows down the Caloosahatchee and St Lucie Rivers.

Final question:

Where do I go to week after week to stay up to date with the Lake as it unfolds?

Answer: Just click on the “Lake” tab at the top of the journal. I usually update the graphs there once a week.


Special thanks to the U.S. Army Corps of Engineers (Jacksonville) and South Florida Water Management District for making all this data available! (BTW, the animation is representative of 2009, not 2010)
