Water Flow Estimate Over a Weir
 *cfs = cubic feet per second *gpm = gallons per minute Use the above table to estimate the water flow over damboards or similar devices. In a stream without such a device, a wooden board (1 inch x 6 inches or 1 inch x 8 inches) can be placed on edge in the stream from bank to bank so that the water flows over the board. Once the average depth and the width of the water over the weir is measured with a ruler (Figure 1), use the table to estimate the flow. For example: water depth = 1.5 inches weir width = 3 feet flow estimate = 3 x 66 or 198 gallons per minute from: King's "Handbook of Hydraulics", Fourth Edition, Table 36.
