The Irrigation Training and Research Center (ITRC) has been working with TCID and USBR as part of the Newlands Project in the Truckee and Carson River basins of California and Nevada. In 1997, ITRC developed a volumetric measurement program to provide documented and reasonably accurate turnout delivery measurements in TCID. This program has involved a series of steps for implementing a volumetric water measurement program, including elements for categorizing, prioritizing, designing, and installing flow measurement devices at turnouts that account for 75% of deliveries (by volume). Since that time, TCID has incorporated ITRC recommendations and has greatly exceeded expectations. As a result of this Water Measurement Program, TCID and USBR have jointly advanced the water measurement program to a point where an accuracy of +/-10% has been achieved on many of the district turnouts.


Presented at SCADA and related technologies for irrigation district modernization: a USCID water management conference on October 26-29, 2005 in Vancouver, Washington.
