| Sumario: | The Paso Bonito reservoir is a source of supply for the city of Cienfuegos and part of the city of Santa Clara. Concentrations of nitrogen and phosphorous in the reservoir and their relationships with the watershed and reservoir management were analyzed on seven dates between September 2006 and November 2007. The reservoir's management was evaluated with respect to water influxes and discharges and the water residence time. In the water column near the reservoir discharge intake the ratio of dissolved inorganic nitrogen to phosphorus indicated that phytoplankton growth was most commonly co-limited by nitrogen and phosphorus or by phosphorus alone. Fifty-two percent of the phosphorous measurements classified the reservoir as eutrophic. Only N-NH4 and PT concentrations changed significantly with depth. Eighty seven percent of the N-NO3 values, as well as N-NH4 during the month of October, indicated water contamination according to the Cuban Regulation used. These results were expected due to watershed and reservoir management. Finally, some issues related to reservoir management are discussed. |
