Here, we have three photos of a section of the Winooski River in Colchester, VT. Between 1927 and 2004, there is a clear change in the floodplain of the river. The riparian zone around the river has increased, however there is more urban development beyond that. The river itself appears to be wider in 1927, likely due to the severe flooding that occurred that year that eroded away at the banks. In addition, there is a small island right before the bend in the river in the 1927 photo that is no longer present in 2004 or 2020. Between 2004 and 2020, there doesn't appear to be much change, which could be due to Hurricane Irene (or any other flood event) not having a severe impact on this part of the state like we saw in 1927.

The Peak Discharge data displayed much greater variability than the Annual Discharge data. This is likely due to the extreme 1927 flood that has the lowest recurrence interval that "stretched" the deviation away from the mean.
The average values for Peak and Annual Discharge are understandably very different from each other; the data shows that on average the peak flow is ~12x greater than the annual flow. This discrepancy can help to determine the behavior of the Winooski during flood events and how much change, on average, we can see to the shape of the channel and the characteristics of the floodplain.
