This essay will present the driving forces behind the liquidation of log-driving from 1930 to log-drivings end in 1980 in Umeälven. The debate about the log-drivers status in the river was multifold. The locals saw log-driving as an inhibiting process where, besides work, nothing good came. The hydroelectric stations saw the log-driving as an unnecessary tool because the hydroelectric stations had a larger purpose and were more prosperous than the log-driving. The underlying factors that evoked the log-drivings dismantling were several. Local people, fishing, hydro, but also the increased demand for forest and technology development. The timber became less ”float-friendly” and the forest road network was developed so that trucks became a more efficient and cheaper alternative, which led to the fact that log-floating was an unnecessary tool for the forest industry.
