Primary spillway on Last Chance Pond is user defined base off of
manufacturer data for 1,0' H Flume (Tracom),
Note; Structure #1 (Dewatering Pond #3), SWS #4 was added to
simulate the volume of 200 gpm (0,45 cfs) coming from
dewatering discharge during the peak storm event. Acreage of
this SWS was adjusted to match the increase in flow,
Dewatering Ponds #1 and #2 were not modeled to allow for a
conservative approach and operational flexibility to divert flow
around these ponds for maintenance,
