"... I portage the dam by putting in below the bridge. The water is not too pushy today, as only one inch of rain had fallen the previous night. However, after a hard rain – two inches or more in a short period of time – the volume of the flow becomes immense. It is not unusual to see a solid sheet of water four feet tall surging violently over the top of the dam. A large hydraulic (recirculating current) forms at the bottom, trapping anything that floats. Being swept over the dam in this type of flow would surely mean death."
