The river's levels and flows are measured at several points along its course, at a number of gauging stations. At Stoke-on-Trent in the upper reaches, the average flow is only 0.6 cubic metres per second (21 cu ft/s), which increases considerably to 4.4 cubic metres per second (160 cu ft/s), at Great Haywood, as it includes the flow of the upper tributaries draining the Potteries conurbation. At Yoxall, the flow increases to 12.8 cubic metres per second (450 cu ft/s) due to the input of larger tributaries including the Sow and Blithe. At Drakelow upstream of Burton the flow increases nearly three-fold to 36.1 cubic metres per second (1,270 cu ft/s), due to the additional inflow from the largest tributary the Tame. At Colwick near Nottingham, the average flow rises to 83.8 cubic metres per second (2,960 cu ft/s), due to the combined inputs of the other major tributaries namely the Dove, Derwent and Soar. The last point of measurement is North Muskham here the average flow is 88.4 cubic metres per second (3,120 cu ft/s), a relatively small increase due to the input of the Devon, and other smaller Nottinghamshire tributaries
