Debris line of river peak at USGS station ID 010642505

Detailed Description

A debris line was left on the ground where the river reached its peak at USGS station ID 010642505 Saco River at Bartlett, New Hampshire. This is a type of High-Water Mark that was flagged for an indirect measurement of discharge. Direct measurements using a flow meter cannot be used during this type of flood event. In this case, it was a slope-area measurement that resulted in 29,100 cubic feet per second of flow, or approximately 2,182,250 gallons of water per second flowing down the channel and well over bank.
