calculated for STA 3/4 from the arithmetic mean of the annual HRT presented in Table
4-15. This value is 33 percent higher than if directly calculated from the long term
average flow and depth. An HRT of 29 days was used for all subsequent long-term STA
3/4 analysis.
The SC STA Scenario's long-term water balance for the 36-year average of the
area, inflows, and outflows were calculated (Figure 4-4). The total average inflow to the
EAASR was 2,705 ac-ft/day. Of this total, 2,201 ac-ft/day was released to STA 3/4. The
average depth of the EAASR was 5.9 feet. Thus, the mean HRT was 67.5 days, slightly
more than two months. STA 3/4 results were equal to the single compartment base
scenario.
