Percentage Of Land Covered In Flood Water And Flood Water Volume Estimates By States (USA)

I’m trying to find some data on flooding frequency and averages for land covered by flood water annually by state. I can’t seem to find any information other than specific address searches. Is there a data set available that would give me any of the information below? – % of land affected by floods annually by state OR – amount of land covered in flood water annually by state – Water volume estimates for floods I searched everywhere and I can’t seem to find anything that fits the criteria.
