Nutrient levels in water reservoirs have been increasing over the years worldwide and fish farming is one of the activities with the potential to cause negative impacts on these environments. Thus, the sedimentation of the main nutrients was evaluated in a reservoir as well as the contribution of aquaculture in raising these rates. The results indicated a significant difference for all nutrients, with higher concentrations in areas near the fish farming, and lower levels in more distant regions. Therefore, assessments that focus only on the water column do not reflect the true impact of this activity.
