The dam was downstream of an automatic streamflow datalogger. The beavers weren't there when we installed the measurement device. Every week we tore down their dam to restore natural stream flow, which we were trying to measure. Some weeks the water level was rising and the stream stagnant by the time we finished our five-hour drive back home. We knew that, because we sampled flow velocity every 15 minutes.
