not form dismantling flood control
from 2016
n recent decades, Lake Okeechobee has been been loaded with excessive amounts of nitrogen and phosphorus from a variety of sources, including fertilization runoff from farms and urbanization, according to John Campbell, spokesman for the U.S. Army Corp of Engineers Jacksonville District.
Such nutrients, along with other environmental factors (such as warmer temperatures), promote the growth of blue-green algae, also known as cyanobacteria.

I agree algae blooms happen and nutrient laden runoff can fuel algae blooms.
What I meant was why has it been only recently that we hear of large volumes of water being pumped into the Caloosahatchee and St. Lucie Rivers?
It isn't for lack of area south of the lake that water could be pumped to let it be filtered naturally. All that has been happening in that region for the past +30 years have been attempts to undo the old flood control system(s), buy farmers out and close/redirect drainage canals.
Why is it only in the past decade that we hear of the present issue?
