Taraldsvikfossen reservoir is a small drinking water reservoir that
has been used to measure ice loads since winter season 2012/13.
The area aound Narvik is the only place in Norway where ice loads on hydropower structures have been measured.
Ice load and environmental measurements at Taraldsvikfossen Reservoir, near Narvik, have been ongoing since
winter season 2012/13, originally started as part of the
The reservoir is
213 m above sea level.
Ice forms in the reservoir each year in fall and persists through approximately May, with the highest loads
seen typically during the first three months of a year.

An early ice cover at Taraldsvikfossen broke up in October 2015 before the final ice cover formed on
12 Nov 2015.
The 2016 water level was too low in Tjårdavatnet during break-up to determine the break-up date
from the camera vantage point. Based on satellite images, the estimate would be around 8 June 2016.
The 2017 water level was low in Kalhovdfjorden and significant snow cover in the field of view obsured
the view of the ice. However, break-up was pretty much complete by 30 May 2017.
