The data shows the latest river conditions provided for flood warning purposes; including river heights, flood classifications and tendency.
The river data shown in these products include real-time operational data from automated telemetry systems and have not been quality controlled. Some of the data are the result of interpolation of observations reported at irregular time intervals.
River height tendency (rising, falling, steady) is calculated by comparing only the latest observation with the previous observation. During times when the water level is fluctuating, such as during a flood peak, the tendency calculated can sometimes be inaccurate. Looking at the plot of the hydrograph is recommended in this situation.
