Fishing Orlando Grande Vista

[Masshole]

I've been coming here for years, but this is the first time I have seen a single fish. I fish for bass, but I usually see multiple fish species along the shoreline nesting or swimming. Today the only thing I've seen is some carcasses in advanced stages of decomposition and not a single bite which is super unusual. I looked for local stories and found a couple fish kills & algae blooms, but nothing in the area I'm at. 
 

Any insight would be appreciated as this is way out of the norm here, and staff here don't seem to know anything (or admitting).

but this is the first time I haven't seen a single fish 🤦‍♂️

We have had relentless cold fronts. Water temps have dropped to below average for this time of the year.  Shouldn't be enough to cause a fish kill though. I never see fish cruising the bank like I do up north so I cant' explain that. Are you from MA ? Totally different game down here.

Definitely NOT a fish kill.  However, if you found a few dead fish, that's a signal the oxygen levels aren't good in the shallows, and fish will abandon those areas for better water quality.

 

Why is the oxygen level low? As @Don51 said, water temps have dropped below average.  The lake likely has abundant aquatic vegetation, which can start to die off as temps drop.  Dying plants consume oxygen rather than produce it.  Plants die off first in the shallows.  Hence, low DO (dissolved oxygen) levels in the shallows.

It was a tilapia die off, water temps in alot of ponds dipped below 55 and even 50 degrees, all the non natives went belly up. All the bass, bluegill crappie, gar, bowfine are fine. 

 

Also a lot of ponds whether it be paid maintenance or FWC on bigger lakes kill weeds, they die make muck and then when it gets super cold it releases a lot of the nitrogen and other gases from the decomposition. This in turn causes algae bloom when it gets warm, there was some of that too but not enough to choke out any fish.
