This year, the Army Corp of Engineers– with input from the South Florida Water Management District, and other stakeholders— has been discharging from Lake Okeechobee into the St Lucie River and southern Indian River Lagoon since January 29th, 2016. Today will review an April update.
We as citizens must pay attention and know what is happening to the river so that we can intelligently fight for its future.
Dr Goforth’s chart above gives a good visual comparison of 2016’s discharges, thus far, compared to those of 1997/98, another El Nino year with fish lesions, fish kills, and toxic algae reports. This chart also compares 2013, our recent “Lost Summer,” when toxic algae blooms filled the river, on and off, for about three out of five dumping months. (–Running May through October, 2013.)
One can see, that Lake Okeechobee’s 2016 discharge amounts are quickly approaching the total numbers released in 2013— although well below those of 1997/98.
Although discharges have been lessened lately, with the Army Corp of Engineers reporting a possible La Nina indications for the 2016 Hurricane season, (4-26-16 ACOE Periodic Scientist Call) considerably more rain could be on the way.
With the lake sitting at 14.29 today, —a high level going into “wet season,” starting June 1st—we should all be watching the situation very closely. Hopefully 2016’s total Lake O release numbers will be nowhere close to 1997/98.
We must continue to advocate hard for a third outlet, and land purchase south of the Lake Okeechobee, as this is the only way to spare our rivers’ repeated total destruction.
Thank you to Dr Goforth for his contribution today.
