Methodology for estimating <br />tributary flow frequency, rate <br />and volume. <br /> <br />x <br />....' <br /><: <br /> <br />II. Near term possibilities of high <br />releases because of current near <br />full reservoir conditions. <br /> <br />III. procedures to combine mainstream <br />releases with tributary flows to <br />establish one-in-one hundred <br />year river flow. <br /> <br />IV. Determination of the duration of <br />one-in-one hundred year river <br />flow event and resulting river <br />water surface elevations upstream <br />and downstream of a tributary. <br /> <br />v. Define Floodway boundaries. <br /> <br />Recommendations <br /> <br />I. The Bureau of Reclamation should use the Task <br />Force adopted techniques and processes as <br />defined in the Methodology for Determining <br />the Floodway Flows and Boundaries on the <br />ColoradO River (Appendix F) in estimating <br />tributary flow frequency, rate, and volume. <br /> <br />II. The difference in release rates for the <br />short term versus the long term was <br />approximately only five percent. The <br />referenced Methodology report is <br />appropriate for determining reservoir <br />release rates and no special consideration <br />is needed due to the current near full <br />reservoir conditions. <br /> <br />III. The procedures described in <br />Methodology report should be used. <br /> <br />IV. The processes defined in Methodology <br />report should be used. <br /> <br />V. The complete process outlined in <br />Methodology report should be used to <br />( det lne the Floodway boundar ies. <br />
