Four expressions from the literature are used to estimate expected retention coefficients for phosphorus, and are compared with measured values, the ranges being 0.50 - 0.66 for the literature-based estimates and 0.47 - 0.68 for the measurements. Estimates are made of the effect that changes in sewage load will have on the annual mean phosphorus and chlorophyll concentration in the lake.
