“…Rivers as sources of freshwater are crucial to the sustenance and prosperity of civilization. Riverine ecosystems are regarded as the most dynamic ecosystems (Choudhury et al, 2022). Rivers provide critical habitats for a wide range of animals, plants, and microorganisms.…”

The Mundeswari River is the western distributary of the Damodar River system in eastern India. The water of this river is extensively used for domestic purposes and agricultural irrigation. This study aimed to evaluate the spatial and temporal water quality variation of the Mundeswari River and assess the water quality status of this river using the Canadian Council of Ministers of the Environment Water Quality Index (CCME-WQI). Water quality was monitored monthly at four selected sampling stations (M1, M2, M3, and M4) during 2020-2022, considering twelve selected water quality indicators. The obtained water quality data were analysed using different statistical techniques. Water quality at different monitoring stations was appraised through the use of CCME-WQI. The results revealed that the overall water quality of most of the monitoring stations based on CCME-WQI values was “marginal.” The highest WQI value (82.01) was observed at M1, and the lowest WQI (41.24) was recorded at M3. One-way ANOVA indicated a statistically significant difference in WQI values between sampling sites (P <0.05). The water quality of the M3 sampling station was found to be in degraded condition throughout the study period. Cluster analysis from the perspective of WQI values revealed two distinct clusters of the sampling stations. Substantial seasonal variation in water quality was also observed. This river had putrid water quality during the pre-monsoon period, and relatively better water quality was evident after the monsoon. This study revealed that the water of the Mundeswari River is utterly unsafe for human consumption and it requires significant treatments before it can be safely used for domestic purposes like cooking, washing etc.

The connectivity of the river–floodplain system during floods plays a decisive role in organisms/matter contribution to the ecosystems of large lowland rivers. We hypothesized that the direction of water-level trends during flood was crucial for zooplankton release from the floodplain into the river channel. The seven-year study of zooplankton in the large plain Ob river suggest that at the inundated floodplain even a slight water level fall brings to plankton release from the floodplain into the river thus causing its abundance boom in the main channel. At water-level stabilization or rise, zooplankton communities of floodplain become isolated from the channel that ceases the recruits’ inflow from the floodplain and brings to a sharp drop in number of river zooplankton. Therefore, it is necessary to take into account dynamics trends (i.e., fall or rise) in river water level when assessing zooplankton density in large lowland rivers. The analysis of such trends should become the basis for predicting of river zooplankton abundance and assessing changes in feeding conditions of fish during the growing season.
