Gönguskarðsá was harnessed in 1947 to 1949.

Gönguskarðsá is a run-off river that flows into Skagafjörður just north of Sauðárkrókur.

The average flow is 3 to 5 cubic metres per second and the catchment area is about 167 square kilometres. In the spring of 2007, the power plant’s supply pipe gave way and there was a lot of damage when mud and water flowed into houses. Construction on the reconstruction of Gönguskarðsárvirkjun began in July 2015.

Verkís managed all the design of structures and equipment and construction supervision. The work consisted of comprehensive services for Íslandsvirkjun, the owner of Gönguskarðsárvirkjun. The power plant can be operated on an isolated network, which means increased electricity security for the residents of Sauðárkrókur.

Verkís worked on the land-use plan and assessment obligation inquiries for environmental issues, handled communication with planning representatives and the National Planning Agency, and worked on cost estimates and project planning. Verkís prepared a project specification for hardware, electrical equipment, and pressure pipes, and assisted in the drafting of contracts with contractors. Verkís prepared the main drawings for the power house and surge basin, as well as designing valve equipment in the intake, pipe route, surge basin, and power house. Verkís conducted an assessment of the dam and prepared suggestions for repairs and handled surveying, monitoring, and assistance during construction.
