Current Lempäälän canal was built between 1867-1874 in the relief efforts. Initially, the channel ran a busy passenger, but after the Hämeenlinna-Tampere railway was completed in 1876, the channel was used mainly to transport goods. In the period 1958-1961 the channel was renewed for timber floating. In this case, the channel shut-off was increased to its present size, and the upper channel was deepened. The channel current appearance is from this period. Channel nowadays mainly serves tourism and is on Finnish Silverline ferry route from Tampere to Hämeenlinna.
