The catchment area of all west flowing rivers is 26,214 Sq.Kms. They are mostly harnessed for power generation. The Western Ghats provides a principal geographical barrier in the path of the Arabian Sea branch of the Southwest monsoon, and is principally responsible for the heavy rainfall over the western coastal belt. The Southwest monsoon season (june to september) is the principal rainy season, over 90 % of annual rainfall is realised in this period.

Ground Water Resources: About 4.4 % of India's ground water resources (2.7 lakh mcum)lies in Karnataka. The total annual recharge of ground water estimated in the state is about 17,99,591 hectare meters(ham). Net annual utilization is estimated at 5,76,921 ham as as on 1991.

The Jog falls in Karnataka are magnificent falls, set in the wild surroundings. Jog falls village is 16 km from the nearest railway station at Talguppa. Trains from Bangalore involve a change in Shimaga town. Nature here has not been disturbed for the tourist tappings i.e unneussary constructions and falling of trees. The Sharavati river crashes nearly nine hundred feet down splitting into four main channels named Raja(king), Rani(queen), rocket and roarer. The highest is the Raja (King) fall which falls 250 m below forming a 40 m deep pool. Next to it is the Roarer, while a short distance to the south is the Rocket it is called so aptly because it spurts great shafts of water out in the air, In contrast the Rani (Queen) over the rocks gracefully.

Just after the monsoon season or rainy season the falls are a magnificient and awesome sight to see. At this time, the falls are surrounded by mists. The 50 km long hirebhasgar reservior now controls the flow of the Sharavati river in order to generate hydro-electricity but inspite of this there is an vast difference between the wet and dry season flow of the waterfalls. The Mysore power corporation releases water to the falls every village has a modest population of about 13, 300.
