•Flood sampling errors can arise from factors beyond small sample sizes.•Even relatively long flood records can be subject to large at-site FFA sampling errors.•Regionally rare and extreme flood events introduce uncertainty to at-site FFA.•Regional and at-site FFA together give better understanding...
