Lake Waubesa Hydrologic Nowcast Modeling

Lake Waubesa Water Budget Schematic and Equation
Lake Monona Schematic

ΔS = VInflow + VPenitto + VNine + VSwan + VP ± VGround − VOut − VEv

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

  • ΔS = Change in Lake Storage Volume
  • VInflow = Yahara River Inflow Volume (from Lake Monona outflow)
  • VPenitto = Penitto Creek Inflow Volume
  • VNine = Nine Springs Creek Inflow Volume
  • VSwan = Swan and Murphys Creek 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 Kegonsa)
  • VEv = Aerodynamic Mass-Transfer Evaporative Loss Volume
