This study is a contribution to the biological assessment and monitoring of Beht’s River quality in Morocco during 2014- 2015 using the standard Global Biological Index of Control and Surveillance Networks (GBI-CSN). Twelve to fourteen sampling stations were chosen to determine impacts of human activities such as agriculture and urban waste management on the biological quality of hydro-systems in the studied area. The results obtained by calculation of the biological index in different stations sampled show the degradation of the quality from the upstream water bodies (Index of Ras Al Ma station: 17/20) to downstream (Index of Dar Elgueddari station: 3/20) of Beht watershed. This deterioration in the quality of the water bodies can be explained by the increase in anthropogenic activity such as the extraction of alluvial materials, intensive arboriculture, and the presence of an uncontrolled public dump downstream of the province of Ifrane as well as the installation of hydroelectric dams that perturb the flow regime of rivers
