the drought has lowered water levels everywhere, see Oct's photo ... that has decreased their living space a great deal.
I've lived in Florida 40 of my 47 years, been around water a much of that time and have never felt threatened by a gator, though a 12ft'er swooshing off a hydrilla bed 20ft in front of your 10ft canoe in the Hillsborough River will wake you up

One of those reported this weekend isn't even a confirmed gator attack, they just found the gator munching on her dead body - she may have had a heart attack before hand - but that ain't news..
I guess if it ain't sharks eatin the inbreeds in FL, it's gators lol
