This study was conducted to monitor, and to assess the water quality of the dam ?Yaacoub Al Mansour? recently filled. The monitoring program concerned the evolution of physico-chemical parameters, bacteria indicating fecal contamination, trophic status and cyanobacteria biomass with their associated toxins. This reservoir is located at 65 km southeast of the city of Marrakech and was filled in May 2008. The main role of the dam is to supply Marrakech city with drinking water. The early occurrence of Microcystis aeruginosa bloom and the hight microcystin concentrations measured just only two years after the set up of the reservoir Yaacoub Al Mansour show the importance to consider the control of microcystins concentrations in the surveillance. So, the bacteriological control cannot be the only indicator of water quality of reservoirs which are intended for the supply of drinking water and it is necessary to consider others parameters. Indeed, management programs of drinking water should take into account the toxicity of cyanobacterial blooms from the setup of the reservoirs to protect effectively the health of humans and animals.
