Kissimmee rises again!

How high is the Kissimmee River?

Answer: High enough to touch the ceiling.

The Kissimmee River has discharged
a little over a half million acre feet
into Lake O this year to date.

That should increase in the weeks ahead.

Of course I mean “ceiling” in the statistical sense.

The above graph shows the current flow rate of the Kissimmee River relative to its 25-year historical stats. The dotted white line in the middle is the 25-year median, the dark green band colors in the area between 25th to 75th percentile, i.e. normal conditions, and extreme flow events, both high and low, are shown by the light green color coding.

The current year is shown as the blue line.

As you can see, it’s on its way to charting new high-water territory on the historic hydrograph.

This calendar highlights
the Kissimmee River’s variation in flow
over the past few decades.

Not that we haven’t had some chart toppers in the past.

The most recent one before this was Fay in 2008 and a three-year consecutive streak summers of a swollen waters in 2003, 2004 and 2005. And don’t forget the spring El Niños. South Florida’s waters usually ebb in spring … unless there’s an El Niño, as happened in 2010 to a degree. But it was 1983 and 1998 that were the big ones.

Then there are times when the Kissimmee falls flat.

Can you see the extended no flow spells in 1981, 2001 and 2007?
