Understanding variations of aquatic community assembly under water diversions and other concurrent stressors is critical for ecological environmental conservation, but hampered by limited research. Mechanisms macroinvertebrate maintaining were determined across five lakes along China’s South-to-North Water Diversion Project, an over 900-km transfer system connecting four major Chinese river basins. We assessed patterns assemblages from 59 sites in relation to attributes describing quality, climate, spatial, hydrologic factors based on multiple-analysis. Macroinvertebrate density, biomass, species richness increased upriver downriver lakes, higher during the period than those non-water period. Non-native species, such as Nephtys sp., Paranthura japonica , Potamillacf acuminata Capitekkidae spp. Novaculina chinensis found entire study system, some which have become dominant lakes. High turnover beta diversity occurred Gaoyou Hongze Hydrology quality are shaping these facilitating non-native dispersal. This has implications lake management conservation stressors.
