Kuthanagere micro watershed is located in Ramanagar district. It was developed in 1995 with bench mark information on GIS and monitored for 19 years for changes in soil- site characteristics. The normal annual rainfall of the Kuthanagere watershed was 1027.6 mm in 45 rainy days. The area under 3 to 5 per cent slope was considerably reduced (by 6 %) as against increase in area (by 13 %) under 1 to 3 per cent slope class. Further the area under moderate erosion was decreased by 4.66 per cent and that became qualified under none to slight erosion class. An increase in overall soil depth of the watershed area by 15.30 cm was observed in 17 years, besides increase in PAWC by 9.98 mm and an overall LGP of 5 days. The area (27% of the watershed) under very shallow soil (7.5 to 22.5 cm depth class) was transformed and became qualified under shallow soils (22.5 to 45 cm depth class). With respect to the change in texture of the soil, sand per cent was decreased by 5.25 per cent as against the increase in silt per cent by 1.76 per cent and clay by 3.61 per cent. Thus the area under sandy loam was decreased by 5.83 per cent and sandy clay loam was in turn increased by 15.4 per cent indicating transformation of watershed area from coarse texture to fine texture soils.

Keywords: Watershed, Length of growing period (LGP), Plant available water holding capacity (PAWC).
