Rainfall plays an essential role in different water management sectors ranging from industries, farming, livestock, and domestic utilization both in rural and urban areas. The surface water bodies like rivers, lakes, ponds, and reservoirs hold a huge proportion of the rainfall. However, due to spatio-temporal variability of rainfall and limited availability of meteorological stations, accurate estimation of the hydrological components such as surface runoff, evaporation, and baseflow is a challenging task. In this study, we have used hydrological information, Soil Conservation Service Curve Number method to develop an empirical relationship between rainfall and runoff in the Telibandha Lake Catchment (TLC), situated in Raipur district of Chhattisgarh, central India. Further, we have used Landsat derived remote sensing product, Normalized Difference Water Index (NDWI) to understand its temporal variation of water spread in the TLC over the fifteen years (2001–2015). The water spread areas are assessed by using the mean monthly NDWI data set and analyzing its seasonal and annual patterns. It is found that Telibandha Lake has a maximum depth of 2.9 m and its surface area is 0.12 km2. Apart from that, the annual runoff is around 232.28 mm, which accounts for almost 22% of the estimated rainfall. The monthly runoff coefficient varies from 0 to 0.25 in TLC. Both the temporal and spatial NDWI plots show that July–September months have high NDWI values in the TLC. The seasonal NDWI showed a good relationship with mean monthly rainfall data and depicts r2 = 0.78. The findings from this study helps in determining the temporal changes of water spread within the TLC and supports in understanding the lake characteristics.
