An ice cover grew across the reservoir from 20 to 23 Oct 2017. Stress cells at stations E and F were installed on 23 Oct 2017, cells at station A were still in place from the season prior.
Three measurement stations were installed at the dam. Station F has one pressure cell installed, while Stations A and E have four cells each. The naming scheme corresponds to the season 2016/17. Load reducers were applied to Stations E and F.
Current measurements are available as Excel 2007 spreadsheet Taraldsvik_consolidated_data.xlsx.
