The first routine measurements of river flow in England began on the Thames and Lea in the 1880s, [2] and in Scotland on the River Garry in 1913. [3] The national gauging station network was established in its current form by the early 1970s and consists of approximately 1500 flow measurement stations supplemented by a variable number of temporary monitoring sites.

In hydrology, a rating curve is a graph of discharge versus stage for a given point on a stream, usually at gauging stations, where the stream discharge is measured across the stream channel with a flow meter. [1] Numerous measurements of stream discharge are made over a range of stream stages.
Measure a length of stream, and mark the start and finish points. The longest length without changing stream conditions is desired to obtain the most accurate measurement. Place an orange at the starting point and measure the time for it to reach the finish point with a stopwatch. Repeat this at least three times and average the measurement times.
As the Stations of the Cross are prayed during the season of Lent in Catholic churches, each station is traditionally followed by a verse of the Stabat Mater, composed in the 13th century by Franciscan Jacopone da Todi. James Matthew Wilson's poetic sequence, The Stations of the Cross, is written in the same meter as da Todi's poem. [37]
A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure.

At a gaging station south of Naper in Boyd County, the river's mean discharge was 138.6 cubic feet per second (3.92 m 3 /s). The maximum mean annual discharge was 389.4 cubic feet per second (11.03 m 3 /s), recorded in 1962; the minimum mean annual discharge was 44.5 cubic feet per second (1.26 m 3 /s), recorded in 1976.
