The Water Measurement Program (WMP) for Truckee-Carson Irrigation District (TCID) began in 1997, when the Irrigation Training and Research Center (ITRC) of Cal Poly State University was asked to develop a volumetric measurement plan for TCID, funded by the U.S. Bureau of Reclamation, Mid-Pacific Region. This program was intended to develop and install reasonably accurate turnout delivery measurement techniques in the district. As part of the WMP, TCID was required to install a number of new open-channel measurement devices. TCID opted for the Replogle flume as its primary flow measurement device using the newly developed WinFlume computer program.

A few key problems prevented TCID from using the typical Replogle flume design that is used in most irrigation districts. For example, the majority of flow measurement sites were to be installed in earthen channels. In addition, the head loss available at each of the sites was relatively small for this type of structure. This required a new design where the cross section and the ramp portion of the flume had to be incorporated in the same construction package. The process used in the design and the unique aspects of construction used on these projects are documented in this paper.
