The graph shows wide variation over the years, and is negative for a significant portion of the time. Clearly in the 1960s RN 5801 was affected by pumping from RN 2680 and RN 2643, and more recenly by pumping from RN 15904. The hydraulic gradient cannot be used to quantify inflow to the Town Basin. Figure H-6 shows the difference between RN 5802 and RN 5803. Predictably the gradient is steepest immediately after river flows. The gradient has been negative at times showing that RN 5802 has been affected by pumping
