N. Platte R. at Lewellen <br /> <br />* <br />Flow input - USBR. Estimated <br />Near Fut~re Flows. <br /> <br />2. Net Reservoir Evap. <br /> <br />Reservoir area times the q~antity <br />(monthly gross lake evaporation minus <br />precipitation on reservoir). <br /> <br />3. Reservoir Seepage <br /> <br />Is the base reservoir seepage plus or <br />minus computed bank storage. <br /> <br />4. Demand on Reservoir <br /> <br />Irrigation Diversions below McConaughy <br />to North Platte plus the difference in <br />Sutherland Losses and Korty Diversions <br />if positive plus the difference in Total <br />Demands at North Platte and Sectional <br />Inflow from McConaughy to North Platte <br />if positive. <br /> <br />5. Reservoir Release <br /> <br />Equals the demands unless Reservoir <br />is empty. <br /> <br />6. Reservoir Spills <br /> <br />Equals the present End of Month Content <br />minus Maximum Content if reservoir is <br />full. <br /> <br />7. Shortage <br /> <br />Is the Demands minus the Releases. <br /> <br />8. End of Month Content <br /> <br />Last End of Month plus, Inflow 1 minus <br />Evaporation 2 minus Seepage 3 minus <br />Demands 4 and Spills 6. <br /> <br />9. Flow at Keystone (Bypass) <br /> <br />Reservoir Release plus Reservoir Spills <br />minus Diversions to the Sutherland <br />System. <br /> <br />10. <br /> <br />Irrigation Diversions <br /> <br />Input <br />North <br /> <br />* <br />data. <br />Platte. <br /> <br />Seven canals above <br /> <br />12. Net Sectional Gain <br /> <br />* <br />Input data. Historic inflow. <br /> <br />* <br />Input data. <br /> <br />11. Inflow from Birdwood 'Cr. <br /> <br />13. Flow at North Platte <br /> <br />Flow at Keystone plus Inflow from <br />Birdwood plus Sectional Gain minus <br />Irrigation Diversions. <br />
