To enhance the productivity and socioeconomic development in agricultural catchment irrigation development is an important issue. The initiation of this study was to evaluate stream flow under land use land cover change for surface irrigation. The necessary data were collected from different respective institution and free available websites. After collecting the necessary data, quality checking and filling of missed data was made. The land use land cover classification was performed using Earth Resources Data Analysis System imagine 2014. The catchment land use land cover of the study area was changed like expansion of residential area, deforestation and increase of agricultural land. The selected land use land cover years of 1994 and 2013 were used for evaluation of land use land cover change impact on seasonal stream flow and to the major components of stream flow. The result depicts that in wet season the stream flow (surface runoff) increase due to this rugged land surface occur so hinder the sustainability of surface irrigation and in dry season the stream flow (lateral flow & ground water flow) decreases so connate water stress the irrigated crops. The coefficient of determination (R2), nash-sutcliff efficiency (NSE), and relative volume error (RVE) were used for evaluating the model performance. So catchment management approach should be done to sustain the catchment for agricultural productivity.
