Abstract

The aim of this study was to evaluate the quality of surface water in Dahod Reservoir, located in Raisen, Madhya Pradesh, India. Water samples were collected from four different locations during winter and summer seasons in 2021. The samples were tested for various physicochemical parameters, including pH, electrical conductivity, total dissolved solids, total alkalinity, chloride, total hardness, calcium hardness, magnesium hardness, dissolved oxygen, nitrate, and orthophosphate. The analysis was performed based on the standard procedures outlined by APHA (2012) and the Workbook of Limnology. The results were compared with the values or ranges recommended by standard organizations such as WHO and BIS to assess water quality. The findings indicated that some parameters exceeded the acceptable limits, such as total alkalinity, total hardness, calcium hardness, and magnesium hardness. To determine the water quality status of Dahod Reservoir, a water quality index was used. The water quality index was 24.4 for the winter season and 31.3 for the summer season. It was found that the water quality was excellent during the winter season and good during the summer season. The water quality index in both seasons was less than 50, indicating that the water is suitable for drinking, irrigation, and industrial purposes. These results are essential for the future management of water in Dahod Reservoir.

Conclusion

The findings from the study were compared to WHO and BIS criteria, and it was found that the majority of parameters in the Dahod reservoir were within acceptable limits during the winter and summer seasons. The water quality of Dahod reservoir was also examined according weighted arithmetic index using 11 physicochemical parameters. The WQI classified the reservoir water as good for aquatic life and fair for drinking and irrigation with overall WQI values of 24.4–31.3 on a scale of 100. The study's findings may be useful in reservoir management for water quality, fisheries, and restoration purposes
