    In the present work we studied the relationship between anthropogenic sources and eutrophication in the reservoirs of the Agoyán and Pisayambo hydroelectric plants and their influence on biomass biodegradation and nitrogen and phosphorus fluxes. For this purpose, field sampling and laboratory analysis were carried out to establish the geographic, geophysical and biochemical aspects of the reservoirs, with the objective of establishing the nitrogen and phosphorus fluxes in order to estimate the influence of anthropogenic sources in the Agoyán and Pisayambo reservoirs. The zones where both reservoirs are located were evaluated to determine possible anthropogenic sources that influence the eutrophication process. Samples were taken in the littoral zone and in the deepest zone of the reservoirs to characterize the main parameters that influence biodegradation in the reservoirs within the water-sediment zone (NO3-, PO43-, chlorophyll, % of organic matter, pH, temperature, conductivity). The results found in this study indicate that the phosphate flows in the reservoirs reported values of 0.4838 mg/L in the Pisayambo reservoir and 0.4988 mg/L in the Agoyán reservoir, these values are outside the permissible limits. The nitrogen content in the Agoyán and Pisayambo reservoirs is not preponderant and has average values of 0.238 mg/L and 0.200 mg/L, respectively. The statistical analysis using Levene's test showed that there is a significant relationship between phytoplankton production and the fluxes of nitrogen, phosphorus and organic matter in the Agoyán and Pisayambo Hydroelectric plants. Finally, the influence of anthropogenic sources on the degree of eutrophication in the zones of influence of the Agoyán and Pisayambo hydroelectric plants was established.
