Veluthodu dam (Malayalam: വെളുത്തോട് അണക്കെട്ട് ) is a part of Kakkad Hydro Electric Project and is located in Seethathode panchayath of Ranni Taluk in Pathanamthitta District of Kerala, India.{{Cite web|title=Kerala State Electricity Board Limited - Kerala State Electricity Board Limited|url=https://www.kseb.in/index.php?option=com_jdownloads&view=download&id=13937:emergency-action-plan-veluthode-march-2020&lang=en|access-date=2021-07-28|website=www.kseb.in}} It's a Concrete-Gravity dam built across the Veluthodu river, a tributary of Kakkad River which is again a tributary of Pamba River.{{Cite web|title=West Flowing Rivers of Tadri to Kanyakumari|url=http://117.252.14.242/rbis/basin%20maps/westflowing.htm|access-date=2021-07-26|website=117.252.14.242}}{{Cite web|title=Fact file on dams owned by Kerala State Electricity Board|url=https://www.expert-eyes.org/dams.html|access-date=2021-07-26|website=www.expert-eyes.org}} The dam is built primarily for electricity.

This diversion dam diverts water to the water conductor system from Moozhiyar reservoir to Kakkad Power Station. This power station utilises the tail race water from Sabarigiri power station and flow received from moozhiyar and velluthode rivers.{{Cite web|title=Kerala State Electricity Board Limited - Pamba Basin HydroProjects|url=https://www.kseb.in/index.php?option=com_content&view=article&id=70&Itemid=717&lang=en|access-date=2021-07-26|website=www.kseb.in}} After power generation, water from Kakkad power station is released to the Kakkad River. Taluks through which release flow are Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally.{{Cite web|title=Diversion Structures in Pathanamthitta district – KSEB Limited Dam Safety Organisation|url=https://dams.kseb.in/?p=190|access-date=2021-07-26|language=en-US}}{{CC-notice|cc=bysa2.5}} It is operated by Kerala State Electricity Board.{{Cite web|title=Kakkad Hydroelectric Power Plant India - GEO|url=http://globalenergyobservatory.org/geoid/43256|access-date=2021-07-07|website=globalenergyobservatory.org}}

Kakkad Hydro Electric Project

The Kakkad Hydroelectric Project generates 50 MW of electricity using 2 turbines of 25 MW each year. The annual output is 262 MU. The machine was commissioned on 16 September 1999. The Moozhiyar Dam creates the main reservoir of this project.{{Cite web|title=Moozhiyar Dam – KSEB Limited Dam Safety Organisation|url=https://dams.kseb.in/?p=125|access-date=2021-07-07|language=en-US}} the second reservoir is formed by the Veluthodu dam.
