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.
