<br />Cl <br />C <br />1-:) <br />.,':';;, <br />0"./ <br />00 <br /> <br />Water Development and Flow Recommendations <br /> <br />The recommended operating rules and flow conditions can be met for levels of development <br />through the baseline depletion levels as defined in Table xx. Development beyond this amount <br />will depend on the specific project proposed and its effect on the hydrograph. To measure the <br />effect of a given project the nature of the project diversion and depletion must be known and <br />projections of the demands in would have placed on the river system for the period of 1929- <br />1993, including points of diversion and return flow, proposed storage reservoirs and proposed <br />operating criteria. The project would then be added to the baseline configuration of the <br />Riverware model of the San Juan Basin, and the model operated for the period 1929-1993 <br />utilizing the specified operating rules. If the hydrographic conditions specified in criteria A - G <br />above can be met, then the project depletion would fit within the specified recommendation. <br /> <br />In some cases, a project may be able to meet these conditions only by taking shortages in critical <br />years. Any proposals for shortage sharing among projects to accomplish the flow <br />recommendations must conform to existing water rights in the Basin and legislation governing <br />the operation of Navajo Dam. Implementation of any proposed shortage sharing must be <br />verified with Riverware to demonstrate that the proposed benefit will be realized and that the <br />conditions proposed are achievable. <br /> <br />Sho in Operation <br /> <br /> <br />In actual operation, dition may exist outside the historical range of variabili water <br />supply and maintenance 0 nditions listed may not be possible. I. ommended that a <br />process for shortage sharing be deve to prevent base flo om being dangerously low or <br />to provide a Navajo Dam release when the n clfied have been exceeded. In such <br />cases, it is recommended that the base fis e a ed to be shorted up to 25% in <br />conjunction with shortages in a upon projects to proVI lcient water to make a release. <br />This will not guaran at all the flow statistics will be met, but a r able, drought period <br />condition e maintained that would prevent a serious setback in the r of the fish. <br />, <br /> <br /> <br /> <br />/ <br />
