Color-Coded Maps – Help Us to Understand the Flow of Lake O

MAP 1.

New maps denoting volumes in 1000 acre feet as presented by John Mitnick P.E., SFWMD – please note for readability, slides have been enlarged into two images.

Today, I wanted to share new map images, “Selected Release Volumes, November 1st, 2018, to May 7, 2019,” being presented at the South Florida Water Management District by Chief District Engineer, John Mitnik P.E. Thank you to Mr Mitnik and his staff for these great images. I really like them and I think you will too as they specifically break down the movement of water from north to south, using color-coding and arrows, making it easier to see and understand the water flows of the complicated Lake O system.

Looking above, notice that the map starts at the top with Orlando’s free-flowing creeks, the often forgotten headwaters of Lake Okeechobee and Kissimmee Chain of Lakes: Their names? “Reedy,” “Shingle” and “Boggy.” Sounds like names from an Everglades’ Seven Dwarves, don’t they?

As you study the map images, above, and below, you’ll catch on quickly with the color-coded arrows and numbers in acre feet. If you wish to compute, use my brother, Todd Thurlow’s easy conversion chart for acre feet: (http://eyeonlakeo.com/DischargeDataandTools/EyeOnLakeOAcreFeetConverter.html)

I’m not going to review each line, just some highlights…but please read through it all!

If you live in Martin or St Luice County, you may find of particular interest RED, RELEASES TO THE INDIAN RIVER LAGOON, (C-25 at Taylor Creek); and BROWNISH-RED, UPPER EAST COAST, DISCHARGES TO THE ST LUCIE ESTUARY, (C-23 and C-24);  for all of us BLUE, TOTAL RELEASES SOUTH, is always important! 550.6 thousand acre feet is really a lot of Lake water “going south.” The original Everglades Forever Act proposed 250,000 acre feet, but it has not always worked out that way.  Some years have been basically null. We should be very happy about 550.6!

 

Map 2

On the southern map you’ll see some of the same colors and number and new ones like OLIVE GREEN, LAKE RELEASES EAST AND WEST; and many more. Most interesting to me right now as the estuaries are not getting bombed is LIGHT GREEN, WATER CONSERVATION AREA 3 RELEASES TO EVERGLADES NATIONAL PARK linked to the L-29 Canal along the Tamiami Trail. It is not just how much water is going south, but how much is getting to the right part of Florida Bay as it is hyper-saline, in parts, leading to massive seagrass die-off. This problem was the first to inspire change and it is still messed up….

In any case, I hope you enjoy these images as much as I do! And following such will certainly help us attain our goals!
