Steingrimsstod Dam is a regulating dam at the natural outlet of Lake Thingvallavatn and forms part of Steingrimsstod, the youngest of the three hydropower stations on the Sog river system.

The power station entered service in 1959 and harnesses the drop from Thingvallavatn to Ulfljotsvatn. A regulating dam was constructed at the lake outlet and water is conveyed through tunnels beneath Drattarhlid towards the station.
