Rainfall increases stream flow and dilutes in-stream conductivity (inverse relationship).

Sensor Fouling Data Patterns

Chart of live storm data showing the turbidity rise in response to increased flow.
Chart showing how turbidity readings increase with algae and leaf accumulation on a sensor.
Charts showing the change in conductivity and turbidity readings when a sensor is cleaned.
Charts showing changes in turbidity readings when debris attaches and detaches from a sensor.
Chart showing how algal growth on a sensor can make it nearly impossible to determine actual turbidity.
Charts showing how high sharp turbidity drop-offs can indicate debris detaching and reattaching..
If depth decreases after a storm but sensor turbidity is still high, confirm turbidity level using a handheld meter.
TurbLow and TurbHigh are essentially the same readings when NTU is less than 250.
