The BATHTUB model was used to generate updated loading capacities for each lake segment that would result in the achievement of water quality standards. This model establishes the relationship between phosphorus inputs to the lake and the effects these loads have on phosphorous concentrations in each lake segment. This report describes how the Lake Champlain BATHTUB model was updated and calibrated using long-term lake and tributary monitoring data. (TetraTech, 2015a)
