Lake Monona Schematic

ΔS = VIn + VStark + VWingra + VP ± VGround − VOut − VEv

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

  • ΔS = Change in Lake Storage Volume
  • VIn = Yahara River Inflow Volume (from Lake Mendota)
  • VStark = Starkweather Creek Inflow Volume
  • VWingra = Lake Wingra Inflow Volume
  • VP = Direct Atmospheric Precipitation Volume on Lake Surface
  • VGround = Net Groundwater and Unmeasured Lateral Flux Volume
  • VOut = Yahara River Outflow Volume (to Lake Waubesa)
  • VEv = Aerodynamic Mass-Transfer Evaporative Loss Volume
