Resumen
El presente estudio diagnosticó la situación ambiental y limnologica, biológico-pesquera y socioeconómica de la "Laguna de Zapotlan" Municipios de Gomez Farías y Zapotlan el Grande, Jalisco y propone programas y estrategias en forma de un Plan de Manejo derivado de los resultados obtenidos. 

Los parámetros fisicoquímicos encontrados muestran los siguientes rangos de valores: temperatura de 16.0 a 26.07 con un promedio de 21.99 oC; oxigeno disuelto de 0.43 a 14.49, con un promedio de 6.63 mg/L, pH de 8.02 a 9.71 con un promedio de 9.33; salinidad de 0.43 a 0.53 con un promedio de 0.49 ppt; sólidos totales disueltos de 0.56 a 0.7 con un promedio de 0.64 g/L y potencial de oxidación reducción de -163.83 a 113.89 con un promedio de -26.242 mV. El oxigeno presenta rangos amplios, tipico de un cuerpo de agua eutrofico. Existe abundante entrada de materia organica como producto de la descarga de aguas residuales urbanas de dos municipios, la cual se acumula en zonas someras en el fondo de la laguna y ocasiona condiciones anóxicas a traves de procesos oxidativos. Los contenidos de nitrógeno, fósforo y clorofila a resultaron altos por lo que el cuerpo de agua se puede clasificar como eutrófico.
