A clear surge and recovery of stream water levels from rain fall

After deploying our latest sensor version to a small local river, we were able to collect some usable stage data during a pretty big rainstorm.

Within about an hour of the rainstorm starting, the stage began to climb at a pretty staggering rate. During its rise, we were concerned that our sensor would become submerged at some point, but the water level eventually peaked about 25 cm from the bottom of our sensor. Needless to say, we would mount the sensor a bit higher next time around.

We noticed that while our sensor data was very consistent before the rain, it became erratic on its way down. After inspecting the sensor, this again turned out to be debris buildup on the sensing pole. We have begun looking into ways to mitigate this buildup or prevent it from affecting our readings.
