Following the reorganisation in the 1860s, the canal was given a new alignment toward the falls. Approximately 60 metres upstream of Pumpafallet, the water was diverted to a new dam situated west of the former watercourse.
With the new dam, the head of water at the former Pumpafallet could be utilised. As a secondary spillway, the Kvarn and Gatgruve falls were used, which by this time had lost their importance after the mill had been relocated to the old sawmill falls.
During its operational period, the dam served to distribute water to the downstream facilities.
1862 – The dam and the Krangruvan pumping wheel were constructed.
1900 – The intake for the Gustav Adolf Mine pumping wheel was built.
1911 – A hydraulic compressor was constructed at Krangruvan. It received water from a new pipe intake in the dam via a pipeline approximately 400 metres long (figure 3).
1924 – An additional penstock was connected to the same pipeline, leading down to a double turbine of 160 horsepower installed in the old smithy.
