In this work, we address the parameter estimation problem for in a lake eutrophication model. It is a dynamic parameter estimation problem, which is solved with a simultaneous approach with an nonlinear programming solver. Gradients of state variables are considered along the column height, rendering a partial differential equation problem which is transformed into a differential algebraic (DAE) one by spatial discretization. Main biochemical and chemical parameters have been obtained, which allow a close representation of the lake dynamics.  Keywords: ecological model, eutrophication, dynamic parameter estimation
