The August 1978 flood washed a lot of boats, buildings, docks, RVs, and cars were washed down stream in the Medina River. Forty-eight inches of rain in three days from Tropical Storm Amelia.
LOL that stuff HAS been there for many many years. It's been there since I can remember as a kid. When the lake has more water in it, you can actually catch fish off of all that stuff. It's not "washing ashore", it's being uncovered by falling water. I have no idea why people are saying it hasn't been there 🤦♂️
