The '''Kolab Dam''', officially known as the Upper Kolab Dam, is a gravity dam built on the Kolab River near Jeypore in the Koraput district of Odisha, India. Constructed at an altitude of approximately 914.4 metres (3,000 ft) above sea level in the Eastern Ghats, it serves as a multipurpose project providing hydroelectric power, irrigation, and drinking water to southern Odisha. The dam is considered one of the most significant infrastructure achievements in the region due to its strategic location, design, and socio-economic impact.<ref name="ohpc">{{cite web |title=Upper Kolab Hydro Electric Project |url=https://www.ohpcltd.com/UpperKolab |publisher=Odisha Hydro Power Corporation |access-date=17 May 2025}}</ref><ref name="swapdial">{{cite web |title=Upper Kolab Hydroelectric Project |url=https://www.swapdial.com/public/knowledge-contents/industrial-data/upper-kolab-hydroelectric-project |publisher=Swapdial |access-date=17 May 2025}}</ref><ref>{{Cite web|url=https://koraput.nic.in/tourist-place/kolab/|title=KOLAB {{!}} Koraput District : Odisha|language=en-US|access-date=2019-01-21}}</ref><ref>{{Cite web|url=http://www.odishabytes.com/four-children-drown-kolab-dam/|title=Four children drown in Kolab dam|last=Bureau|first=O.

== Characteristics ==

The Kolab Dam is a straight masonry gravity dam situated near Jeypore in the Koraput district of Odisha, India. Constructed across the Kolab River, a tributary of the Godavari, the dam stands at a height of 54.5 meters and spans a length of 630.5 meters. It is located at an elevation of approximately 914.4 meters (3,000 feet) above sea level, making it one of the highest-altitude reservoirs in Odisha.<ref name="ohpc" /><ref>{{Cite web|url=http://india-wris.nrsc.gov.in/wrpinfo/index.php?title=Upper_Kolab_Dam_D01660|title=Upper Kolab Dam D01660 -|website=india-wris.nrsc.gov.in|access-date=2019-01-21}}</ref>

The dam features an ogee-type spillway equipped with 11 radial gates, each measuring 12.2 by 12.2 meters, designed to handle a maximum flood discharge of 10,020 cubic meters per second. The reservoir has a gross storage capacity of 1,215 million cubic meters and a live storage capacity of 935 million cubic meters, covering a catchment area of 1,630 square kilometers. The water spread area at full reservoir level is approximately 114.32 square kilometers.<ref name="ohpc" />

The hydroelectric power station associated with the dam comprises four Francis-type turbines, each with a capacity of 80 MW, totaling an installed capacity of 320 MW. The plant utilizes a net head of 253 meters and generates approximately 832.2 million units of electricity annually, which is distributed to the regional grid via the Jeypore substation.<ref name="powertech">{{cite web |title=Power Plant Profile: Upper Kolab, India |url=https://www.power-technology.com/marketdata/power-plant-profile-upper-kolab-india/ |publisher=Power Technology |access-date=17 May 2025}}</ref>

In addition to power generation, the dam supports irrigation over an area of 47,985 hectares and supplies drinking water to the towns of Damanjodi, Koraput, Sunabeda, and Jeypore, thereby playing a crucial role in the socio-economic development of the region.<ref name="ohpc" /><ref>{{Cite web|url=https://odishatv.in/odisha/people-risk-lives-to-cross-kolab-reservior-in-koraput-a-ground-report-311366|title=People risk lives to cross Kolab reservoir in Koraput: A ground report|website=odishatv.in|language=en-US|access-date=2019-01-21|archive-date=2019-01-21|archive-url=https://web.archive.org/web/20190121233032/https://odishatv.in/odisha/people-risk-lives-to-cross-kolab-reservior-in-koraput-a-ground-report-311366|url-status=dead}}</ref>

== History ==
A possible idea of "A project of Kolab dam" were first come during the British Rule when Koraput district was a part of Madras presidency.
