Short summary

Based on large, long-term and high-quality data sets, this study describes the mitigation of eutrophication in the Loire River basin since 1980. Reducing direct phosphate inputs in the early 1990s has led to a significant decrease in algal biomass although Corbicula spp. clams invaded the river during this period and have probably played a significant role in phytoplankton decline. A powerful trend and seasonality analysis showed that these changes considerably affected river biogeochemistry.
