Gully, Kevin, the rain water likely has a very high salinity as hurricanes often have water blown up out of the ocean instead of clouds formed from evaporated, re-condensing moisture.
Thanks, Rex. That certainly seems like a plausible explanation for a pond which is near the coast; however, as a crow flies my pond is more than 150 miles from the coast.
A couple of other times over the past 6 years the pond's water has cleared after a heavy rain shower which was not even associated with a tropical event, only to be muddied again by runoff from the next heavy shower.
Maybe it has something to do with water temperatures, air temperatures, DO levels, and what-not and everything. lol
