It can be defined as minimum 7 day flow with a return period of 20 years. I am not clear about the 7 day thing here, i believe it has to be a moving average on daily flow data values.

Call the USGS District office in your State and speak with the District Surface Water Specialist. He can provide you with the value and the error associated with that value.
