Is this hydrograph too busy?

Peak water is riding high ...

But for how much longer?

The hydrograph above shows a multi-parameter overview of hydrologic conditions in Big Cypress National Preserve, Dec 2010 to present.  While there is merit to putting lots of data all in one spot to see, there is also a risk of making a graph that is too busy to reasonably view.  From top to the bottom, the monthly rainfall, average preserve-wide swamp stage, a regional water table comparison, and sheetflow under the Tamiami Trail area shown.  Trends worth noting?  Waters are currently peaking but it's been a relatively short stint of water in the higher terrain, i.e. pines, this year.  Some areas, such as OK Slough and East Hinson Marsh (as indicated by BCA2 in the second graph from the bottom) barely got wet at all.  Projecting into the future, the dotted white lines (i.e. long-term median) shows water to also be on the verge of a slow and steady decline.

September is the last core month of the summer rainy season.

The peninsular afternoon rain shower machine shuts down in early October, right around Columbus Day. After that, we're left looking toward the tropics for a possible last hurrah from the wet season.


Last year, you may remember, October did not disappoint.

Hi Bob;

I find your graphics very informative. Laypersons may find the graphics too busy, but I think your audience is primarily hydrologists, engineers and scientists. So most of the professionals should find the wealth of information very informative.

You certainly have designed some creative ways of displaying data. In addition to the information, I go to gohydrology.org to get ideas for creative displays of hydro-related data.

Thanks for making a difference Bob!

I agree with Cal! I think your graphics are excellent... I look at them all the time. It's not very often that you see the hydrology and the ecology so closely linked in the presentation of hydrologic data. Thanks so much for the great work displayed at this web site.
