             abstract = "Water stored in dams and reservoirs is essential element for 
                         hydrological cycle and other human activities like irrigation 
                         farming, fishing and transportation. Reservoirs in arid and 
                         semi-arid environments tend to change in volume and area extent 
                         over time as a result of natural and human factors causing water 
                         shortage. This study examines the spatiotemporal changes of 
                         Goronyo reservoir, Nigeria from 2000-2020. Landsat imageries were 
                         used to extract the surface water area using Modified Normalised 
                         Difference Water Index (MNDWI). The changes in the spatial and 
                         temporal pattern of the surface water over were obtained by 
                         calculating the differences in the surface area over the study 
                         period (2000-2020). The results show a continuous decrease in the 
                         surface water indicating loss of water. The surface area changed 
                         from 105.24km2 (98.35%) in 2000 to 72.01km2 (67.30%) with a total 
                         constriction of 33.22km2 (46.13%). Increase in temperature and 
                         evaporation and anthropogenic activities are the major factors 
                         responsible for the changes. Planting of trees around the water 
                         and dredging the silt to restore the water to its full capacity 
                         will mitigate the high rate of water loss for sustainable 
                         socio-economic development.",
