A steady state mathematical model for the total coliform distribution in Grand Traverse Bay has been developed using continuity equations and experimental data describing die-away kinetics. Advective and dispersive transport phenomena were approximated using square-law assumptions and field dye tracer techniques. The predictive capability of the model was verified by comparing model calculations with observations during quasi-steady periods in 1963, 1964 and 1971. The utility of the model was demonstrated with two examples showing coliform distributions resulting from alternate waste disposal schemes.
