WCFSP include a diversion structure replacement at the Silt Water Conservancy District, Silt, and installation of a long - throated (ramp) flow -mea- surement flume at the Florida Water Conservancy District, Durango.

Technical Assistance and Information Reclamation provides technical assistance through both Regional and Area Offices, and from Reclamation's Technical Service Center (TSC) lo- cated in Denver. Reclamation's Western Colora- do Area Office (WCAO) is part of Reclamation's Upper Colorado Region and is located in Grand Junction. The WCAO has recently been an active partner in providing technical assistance for the Grand Valley Irrigation Company's moderniza- tion project on the Government Highline Canal. The Eastern Colorado Area Office (ECAO), located near Loveland, is part of Reclamation's Great Plains Region. The ECAO is currently a partner in efforts by the Northern Colorado Water Conservancy District to establish demonstration sites for canal monitoring and data telemetry technologies. Reclamation's Water Resources Research Labora- tory (WRRL) which is part of the TSC in Den- ver is closely involved in providing technical assistance and information in support of canal modernization projects. The WRRL annually offers training opportunities such as the five - day "Modern Methods in Canal Operation and Control" and the three -day "Basic Principles and Developments in Flow Measurement" workshops utilizing a model canal - simulation facility. Both courses integrate classroom instructional sessions with "hands -on" experience with the laboratory's canal model. Information on these classes can be accessed at: http://www.usbr.gov/pmts/hydrau- lics—lab/workshops/ Information sources related to canal moderniza- tion available from the WRRL include: • Water Measurement Manual, Third Edition. This 1997 update was produced by the WRRL staff in cooperation with both the Agricultural Research Service and the Natural Resources Conservation Service of the USDA. It is avail- able from the US Government Printing Office, or may be downloaded in .pdf format at: http: // www.usbr.gov/pmts/hydraulics_lab/Pubs/manu- als/WMM-3rd-2001.pdf • WinFlume, a Windows -based software for de- signing long - throated flumes and for calibration of "as built" long throated flumes. WinFlume may be downloaded at: http: / /www.usbr.gov/ pmts/hydraulics_lab /winflume /. • USBRWeirxls, an Excel spreadsheet -based program for creating ratings tables and simplified weir equations for common sharp- crested weirs. The simplified weir equations are more easily incorporated into canal automation programming than previously available weir relationships. USBRWeir.xls is currently available for beta test- ing. It can be downloaded at: http: / /www.usbr. gov/ pmts / hydraulics _lab /usbrweir /index.html. Members of the WRRL staff, working through agreements with Reclamation Area Offices are conducting on -site assessments and providing technical assistance to canals seeking improved flow measurement capability and/or automated control in the Belle Fourche and Angostura dis- tricts in South Dakota, the Pioneer district which spans the Colorado/Nebraska border, the Carls- bad district in New Mexico, the Truckee- Carson district in Nevada, the Yuma Mesa district in Arizona, and the Moon Lake Water Users Asso- ciation in Utah. RD3 of Appropriate /Affordable Technologies WRRL staff members are active in numerous areas of canal operating technology development and demonstration, supported both by Reclama- tion's Science and Technology (S &T) Program, and in partnership with Reclamation Area Of- fices. A key focus has been identifying and developing technologies that are affordable for 15
