Impact of Tehri Dam on aquatic macroinvertebrate diversity of Bhagirathi, Uttarakhand
Aquatic macroinvertebrate diversity in the Bhagirathi river was monitored for the period of twelve months (September 2004 to August 2005) for assessing the impact of Asia's highest dam, Tehri Dam. Comparative data on diversity of macroinvertebrates revealed that the number of taxa in the downstream stretch, especially close to the dam was significantly reduced.
