I grew up between Highway 6 and Eldridge on West Little York. Those two reservoirs flooded both of those roads more times than I can count between I-10 and Clay Rd and Highway 6 south of I-10. I don't know how anyone who has lived in Houston for more than a few years does not know that by now.
That said, through the worst of floods, my childhood home never flooded. Harvey flooded it.
