==Power generation== The dam is intended for [[hydroelectric]] purposes and is part of Stage I of the Ranganadi Hydro Electric Project and supports the {{convert|405|MW|adj=on}} '''Dikrong Power House'''. The {{Convert|68|m|abbr=on}} tall dam diverts water south into a {{Convert|10.1|km|abbr=on}} headrace tunnel which is then transferred into a {{Convert|1062|m|abbr=on}} [[penstock]] before reaching the three {{convert|135|MW}} turbines.<ref>{{cite web|title=Ranganadi Hydro Electric Project Stage I|url=http://www.neepco.gov.in/ranga1.html|publisher=North Eastern Electric Power Corporation|accessdate=28 August 2010}}{{dead link|date=April 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Since commissioning, the power house has been generating much less than its capacity because of drought.<ref>{{cite web |title=Reservoir of dams |url=http://www.indiaenvironmentportal.org.in/content/reservoir-dams |publisher=India Environmental Portal |accessdate=28 August 2010 |date=May 2008 |archive-url=https://web.archive.org/web/20100124034901/http://www.indiaenvironmentportal.org.in/content/reservoir-dams |archive-date=24 January 2010 |url-status=dead |df=dmy-all }}</ref>
Stage II of the project is designed to provide water storage for Stage I and includes a {{Convert|134|m|ft|abbr=on}} rock-fill embankment dam with a {{Convert|523000000|m3|ft3|abbr=on}} storage capacity. This dam will support an additional {{convert|180|MW}} [[power station]].<ref>{{cite web |title=Ranganadi Hydro Electric Project Stage II |url=http://www.neepco.gov.in/ranga2.html |publisher=North Eastern Electric Power Corporation |accessdate=28 August 2010 }}{{Dead link|date=November 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
