The article discusses the project of a water canal planned from Plzeň to Regensburg and designed by a leading Czech hydraulic engineer, Antonín Smrček, in 1922. The presented study is not only aimed at describing the technical solution of the canal, acquired on the basis of exploring the inheritance collection of A. Smrček, but also at mapping out the wider context of ideas concerning the construction of the water canal from Prague to Plzeň and further to Germany in the course of the 20th century.
