In recent news reports, it was reported that “following the drastic fall in the water-level in the Shiva Balancing Reservoir (SBR), the Bangalore Water Supply and Sewerage Board (BWSSB) has asked Karnataka Power Transmission Corporation Ltd. (KPTCL) and Karnataka Power Corporation Ltd. (KPCL) to stop power generation from four mini-hydroelectric projects in the Cauvery basin, at least till May.”[1] The projects which were asked to stop generation include: Madhavamantri, Satyagala, Shiva Anecut and Shimsha mini-hydroelectric projects.
However, the fact is that KREDL (Karnataka Renewable Energy Development Limited) has allotted and commissioned a whopping 98 mini hydel projects on the Cauvery, most of them downstream Krishnaraj Sagar Dam, many of them commissioned. These projects are in the Mysore, Mandya and Chamrajanagara Districts. Actual numbers maybe higher as we have not included projects from Ramanagara in the list as we are not certain how many of those would fall in Cauvery Basin.
24 Projects are in Mysore, 62 in Mandya and 12 in Chamrajanagar.
See Annex 1 for the full list with their status (Only projects from Mandya in the Annex, contact us if you need the full list)
Some of these projects are downstream from the Shiva Anicut from where water supply to Bangalore is routed. In addition to decrease in water availability, water stored by several mini hydel projects increases the evapo-transpiration rate of water, particularly in summer.
Critically, these projects also hold back water, affecting water supply cycles to Bangalore and other towns and villages dependent on the river. Similar conditions had occurred in Mangalore, last year where water levels in the Thumbe Dam fell to alarming levels due to mini hydel projects hoarding up water in the upstream.[2]
In Cauvery, if at all the state government, BWSSB and others concerned about impact of water supply due to mini hydel projects, they need to consider the impact of these projects on the water supply, ecology and livelihoods in the downstream areas and consider halting generation of these projects during this summer when the Cauvery basin is facing sure dire water situation. Mini Hydel Projects which are below the capacity of 25 MW do not need Environmental Clearance, Environment Impact Assessment or Public Hearing. String of Mini Hydel projects on a single river, one after the other, severely affects the hydrology as well as ecology of a river system and also people and their livelihoods in surrounding areas. The same is happening with Cauvery with nearly 100 Mini Hydel projects planned or commissioned. Many projects are right next to the Cauvery Wildlife Sanctuary and are causing impediment to movement of elephants, increasing man-animal conflicts. This has been highlighted by the Karnataka Elephant Task Force. Due to their cumulative impacts on ecology, High Court of Karnataka has halted construction of any such projects in Western Ghats.
Hence, keeping water supply, hydrology and ecology in view, project level and cumulative impact assessment of mini hydel projects planned, allotted and commissioned along the River Cauvery is an urgent need. Earlier such appeals to KREDL, Karnataka Forest Department and Karnataka Wildlife Board have fallen on deaf ears.
We hope that the Karnataka government, BWSSB, KPCL, KREDL, KPTCL, Cauvery Neeravari Nigam and all others concerned will come together and will conduct this assessment urgently and cancel the projects which are having unacceptable impacts on people, ecology, hydrology and water supply of Cauvery. Immediately, an assessment of their impact is required in the context of summer and dire water situation.
On the International Day of Action for Rivers, Cauvery needs our urgent attention. Cumulative impact Assessment and individual Impact Assessment of unprecendeted number of Mini Hydel Projects is a must.
