In this study, algae and microcystins (MC-LR and MC-RR) were studied in 6 reservoirs in the northeastern part of Haihe River Basin. The results indicate that the eutrophication degree of most reservoirs has been obviously improved, but Yuqiao reservoir and Yanghe reservoir are still in the state of eutrophication. The MC-LR and MC-RR were also detected in Yuqiao reservoir and Yanghe reservoir. In addition, cyanobacteria were dominant spices in the eutrophic reservoirs, and the concentration of microcystins was positively correlated with algae density. Although the concentration of MC-LR is lower than the concentration limits of sanitary standard for drinking water. It is suggested that it should be monitored during the outbreak of cyanobacteria, especially in the later stage of outbreak considering a risk for the health of the water supply population.
