SENECA II MINE
Pond 004
HYDROLOGIC INPUT PARAMETERS
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.
