A solid ice cover formed in the morning of 16 Oct 2016, reaching 15 cm thickness by 28 Oct. Stress cells were installed on 28 Oct and connected the following day.
Six measurement stations were installed at the dam. Stations B and F have one pressure cell installed each, while Stations A, C, D, and E have four cells each. Vertical levels are aligned between stations with all sensors in Station C mounted 3 cm low. Load reducers were applied to Stations B, C, E, and F. Station D measures stresses in the narrow ice bridge between Stations C and E.
Ice load tests under varying water level started on 7 Mar 2017.
Current measurements are available as Excel 2007 spreadsheet Taraldsvik_consolidated_data.xlsx.
