One-dimensional vertical models \nof GW flow (MODFLOW-2005) and solute transport (MT3D-USGS) were calibrated \n(UCODE) to 2014 observed dissolved silica (Si, 0.2-micron filtered) porewater \nconcentrations in the upper 0.1 m of lakebed sediment to estimate GW flow and \nSi exchange across the lakebed interface. The Si-based calibrated GW flow rates \nwere then used in conjunction with observed dissolved phosphate-phosphorus (PP) \nporewater concentrations in the upper 0.1 m of lakebed sediment to estimate the \namount of PP reacted during upward flow through the lakebed sediment and the \nPP discharge to the lake. One-dimensional, vertical GW flow and heat transport \nmodels (VS2DH) were calibrated (UCODE) to 2015 and 2017 observed lakebed \ntemperatures to provide estimates of GW-inflow rates at multiple UKL locations. \nCalibrated GW inflows were greatest in the spring and decreased through the \nsummer. The magnitude and timing of the GW-lake water exchange estimates \nobtained from these methods were compared to rates obtained from a generalized \ncross-sectional GW flow model (MODFLOW-NWT) with time-varying recharge. \nThe cross-sectional GW flow model demonstrated that snow-melt GW recharge \ncould be transported rapidly to the lake due to the relatively high permeability and \nlow specific storage of the surrounding volcanic rocks explaining the greater GW \ndischarge to the lake in the spring.
