Abstract: Soil conservation has become an integral part of land use that contributes in enriching social and economic environment by improving soil capital. Primary principles of these measures are to control soil erosion by reducing raindrop impacts on the soil, reducing runoff volume, velocity and increasing the soil resistance to erosion. The objective of this study was to analyze the impact of soil conservation measures on water yield in the reservoir that has taken place in the last 24 years in the Sukhna watershed located in Chandigarh, partly in Punjab and Haryana. To achieve the objectives of the study comparative analysis was carried by taking all the parameters such as rainfall, runoff, vegetation, soil conservation structures, evaporation, annual runoff and estimated seasonal runoff for the years 1989 and 2013. The analysis shows direct impact of soil and water conservation measures on water yield which reduced from 27.14% of annual rainfall (1989) to 7.9% of annual rainfall (2013) and 13.68% of seasonal rainfall (1989) to 12.7% of seasonal rainfall (2013) from the catchment. The analysis indicates that with the increased in number of structures and water bodies in the catchment there is a reduction of water yield in the Sukhna Lake because water does not reach to Sukhna Lake unless the water bodies are filled. To maintain the beauty of the Sukhna Lake, maintains of the present soil conservation measures in the catchment it is prime importance to ensure sustained water yield, constructing additional structures in the catchment may adversely affect the Sukhna Lake and its ecosystem.
