To meet the demand of food and water for exploitation of water resource is going on incautiously at several parts of the country. For sustainable crop yield and water harvesting land and water resource conservation is very much essential. Without proper replenish of aquifers along with natural environments socio economic condition of a society may face the challenge of extreme degradation. The selected study area, Nayagram block is fallen under poor water resource and high soil erosion zone. For the development of land and water resources of the area watershed management is found to be an idle option which is presently active in only 97 Km 2 (19.36 %) areas. To get more area under the control of watershed management project present study has conducted watershed prioritization through GIS study by dividing the area into 37 sub watersheds. For deriving the morphometric information of each sub watershed Digital Elevation Model (DEM) have been used. Prioritization was performed as per rank method by integrating several morphometric parameters of watersheds into account. As per study 7 sub watersheds have been found as prioritized sub watershed which will put additional 75.11 Km 2 new areas under management. For the management of 7 vulnerable watersheds conservation site was selected by considering the various physical aspects like LULC, soil, slope and stream order.
