Lake Wingra Schematic

ΔS = VLocal + VP ± VGround − VOut − VEv

Variables and definitions (units in model are acre-feet):

  • ΔS = Change in Lake Storage Volume
  • VLocal = Local Surface Storm Sewer Inflow Volume
  • VP = Direct Atmospheric Precipitation Volume on Lake Surface
  • VGround = Net Groundwater and Unmeasured Lateral Flux Volume
  • VOut = Wingra Creek Outflow Volume (to Lake Monona)
  • VEv = Aerodynamic Mass-Transfer Evaporative Loss Volume
Inflow - Storm Sewer Inflow
