<br />. <br /> <br />. <br /> <br />. <br /> <br />Status of Projects <br /> <br />The total authorized amount for this project was $175,000. To date, approximately $139,000 has been <br />either disbursed or encumbered. The following table provides a quick summary of the selected projects <br />under the CWCB's gaging program and the status of the work. <br /> <br />Pro i ect <br />Coutract with the USGS for the development of <br />methodologies to measure late-season and winter stream <br />flows particularly in streams that are frequently affected <br />by ice. The USGS will be determining the usefulness <br />and accuracy of ice-affected streamflow records using a <br />sodium chloride tracer. The tracer will be injected at <br />two different gaging stations. Multiple-parameter. <br />sensors at the two sites will monitor background and <br />peak-tracer concentrations and relative conductance. <br />These data will then be used to determine streamflow at <br />each site and the tracer-discharge measurements will be <br />compared to discbarge determined from standard gaging <br />station operations. The data collected will ultimately be <br />published in a USGS Open-file Report and a <br />presentation will be given to CWCB staff. It is hoped <br />that this new technology will lead to more accurate flow <br />data during the late irrigation season and winter months. <br />Floodplain high flow warning system and ISF low flow <br />warning system utilizing existiug satellite gages. This <br />project will involve coordination with both the DWR <br />and USGS, as well as IT programming that will <br />automatically alert CWCB staff when low flow <br />conditions exist. <br /> <br />Flood Hardening and Rating Curve exteusions at gages <br />throughout the state. Flood Hardening involves the <br />evaluation of gages that are critical to the state and then <br />implementing measures to safeguard those gages during <br />high flow events. Rating Curve extensions involve an <br />extension of a gage's rating curve so that it can <br /> <br />Page 23 of31 <br /> <br />Status <br />This project was completed under budget. <br />The USGS is currently evaluating the data. <br />It is expected that the results will be <br />available later this summer with a complete <br />presentation to staff. A more complete <br />report to the Board on the study results <br />should be available at the September 2002 <br />Board Meeting. <br /> <br />Funds allocated to the CWCB gaging <br />program for FY 2002/2003 will be used to <br />continue the development of alternative <br />gaging methodologies. The next anticipated <br />study will evaluate dye-dilution gaging <br />methodologies. <br /> <br />This project was delayed as DWR evaluated <br />their ability to implement the project through <br />a contract with an outside professional firm to <br />develop the software and technology to <br />implement the project. However, on June 18, <br />2002, everyone accepted a proposal by SM <br />Technical Consultants. The consultant will <br />be able to do the initial work under budget, at <br />a cost of approximately $5,000 and should <br />complete the work within approximately <br />three months. <br /> <br />Additional funds were budgeted for the <br />continuation of this project into 2002/2003. <br />As the project progresses, staff will evaluate <br />the need for additional capabilities and <br />refinement of the system. For example, one <br />proposal would involve the integration of the <br />system into the statewide DSS. <br /> <br />The funding allocated to this project for FY <br />2001/2002 has been disbursed and the <br />project has been completed. However, <br />Additional funds were requested and <br />approved to continue flood hardening <br />efforts into 2002/2003. The CWCB, DWR, <br />
