A two‐box lake model is presented with the subsystems epilimnion (E) and hypolimnion (H) and phosphorus as the limiting nutrient factor. The mean O 2 consumption in H as a function of P loading is calculated and critical P‐loading figures above which the lake turns toward eutrophy are given for varying lake mean depth z and hydraulic loading factor q s . The results agree with an empirical relation between z and P loading given by Vollenweider. In addition, P retention factors are calculated using the model and compared to measured values.
