Abstract :
The Latvian Government is in possession of various plans for the installation of hydroelectric stations on the Duna (Dvina) River, which, for the most part, were developed by engineers of the Imperial Russian Government prior to the war. These plans constitute a somewhat complete scheme for utilizing the power of the Duna and also for developing the river, through a system of locks and short lateral canals, to make it navigable well into the interior of Russia proper and eventually, through a system of canals connecting with the Dnieper and other Russian rivers, to form an elaborate system of interior water transportation.
