| Note: Gains in excess of losses on the reservoir will be considered Rio Grande that will be released when feasible. | ||||
| (1)This column is computed using the data on Table 3, the Net Evaporation on Table 2(2) and the Computed Inflow (Col. 5 on Table 1). To compute unaccounted Rio Grande inflow to Heron. (Current EOM content, 3(8)-[Previous EOM content, 3(8)+3(2)+1(5)-3(3)-3(4)-2(2)])=Unmeasured Rio Grande inflow to Heron Reservoir. | ||||
| (2)Computed Net Evaporation from weather data. | ||||
| (3)2(1)-2(2). Set to zero if 2(1)-2(2) is less than zero. | ||||
| (4)Computed reservoir seepage. | ||||
| Data Current as of November 5, 2009. | ||||
| NA=Data currently unavailable. | ||||
