    Modification de l'hydrologie: Aquatic weeds such as the L. peruviana, which has been previously recorded in Burnt Bridge Creek, are known to restrict the flow of water in creeks. This may be why flow before the dam (where the most amount of weeds were recorded) was less than that downstream (Sadler and Dempsey, 2002).
