The loss of connectivity is a ubiquitous threat facing rivers worldwide considering the numerous river infrastructure projects that exist worldwide and continue to be commissioned to meet humanity’s growing demands for hydropower, flood control, and water supply. Not surprisingly, freshwater ecosystems are among the most altered and threatened globally.

Why fishermen fear Netravati river diversion
Changing the course of Netravati is feared to affect the fish population in the river which will, in turn, affect the fortunes of the fisherfolk dependent on it. Posted on 09 Dec, 2017 04:36 PM

Rathnakar Salian is a traditional catamaran fisherman from Sasihitlu village in Mangaluru district of Karnataka. He learned how to throw the net, how to pull it out, and how to look for fish in the sea from his father and uncles.

Pipelines wait to be laid for the stormwater lift project. The Karnataka Niravari Nigama Limited (KNNL), which is undertaking the Yettinahole stormwater lift project, is constructing a massive pipeline corridor along the Salkeshpur-Hemavati belt. The project is estimated to be 35 percent complete.

A costly 200 km journey from source to tap
The Yettinahole Diversion Project aims to supply water to water-starved Kolar and Chikkaballapur in Karnataka. Diverting the Netravathi river for this purpose need not be the only solution. Posted on 23 Mar, 2014 10:40 PM

In July 2012, the Government of Karnataka approved the Yettinahole Diversion Project (YDP), which will cost an estimated Rs. 12,912.36 crore. This project is set to divert the head waters of the Gundia River (a tributary of the Kumardhara, which is a tributary of the Netravathi) in the west and transfer it to eastern parts of the state.

1 dam, 2 projects, many fools?
Two different hydroelectric projects on a single dam built on the Nethravathi hide under the guise of a mini-hydel project and blatantly flout green norms. Is this another scam? Posted on 22 Dec, 2013 05:49 PM

I was looking for Greenko’s 24.75 MW Perla Mini Hydel Project at Perla village near Bantwal, Mangalore. One would think that you wouldn't really have to search for a hydel project site given its size and scale but the villagers at Perla were puzzled when I asked them to take me there as the Project Design Document had noted the project location as Perla village.
