Design depth was the next key sizing decision. Four design depths were considered with nominal design depths of 6, 10, 12, and 14 feet. These alternatives were named AltlR, Alt2R, Alt3R, and Alt4R, respectively (USACE and SFWMD, electronic correspondence, April 8, 2005). The compartments in all Alt_R configurations were termed Cl and C2, as in previous configurations. The depth and area used to achieve this total volume were varied in each alternative; however C2's area remained fixed at 17,920 acres. The associated areas of Cl were developed to yield a capacity of 360,000 acre- feet. The area, depth, and volume of the Alt_R configurations and the original Alt 3 simulation are presented in Table 3-1. Table 3-1.

Configurations to assess the effect of compartmentalization and the source of inflows were then developed. The configurations are presented in detail next. Compartmentalization Configurations Unlike previous configurations, the compartmentalization of the reservoir affects the inflow sources to STA 3/4. Therefore, details on both the EAASR and STA 3/4 are included for each configuration. The EAASR was modeled as 12 SFWMM cells incorporating 30,720 acres of area and STA 3/4 was modeled as 7 SFWMM cells incorporating 17,920 acres of area (USACE and SFWMD, electronic correspondence,
