Springs SSSPGI and SSSPG2 are perennial flowing springs that flow directly to Pond 004. The average flow
rate fo rthe springs is 0.7 cfs (0.35 ac-ft/day). The permanent pool elevation in the model was set at 6,948.52
feet (for the 10-year, 24-hour event demonstration) to account for the perennial inflow in the modeling results.
The permanent pool elevation for the 25-year, 24-hour event demonstration was set at 6,950.5 feet.
