[en] In this report we give the documentation for LAKONT, a multi-trophic level model for energy flow and population dynamics in the neighborhood of the Nine Mile Point and Fitzpatrick nuclear power stations. The model contains equations from models reviewed from the literature and is designed to compare the behavior of models put together with different combinations of the reviewed equations. Here we give the equation forms and rationale, a description of the biotic and spatial structure of the models, a list of notation and parameter values and reference to the sources of data used to estimate parameter values and run the model
