The Neugrabenflöße (also called the Floßgraben), was a roughly 18 km long Kunstgraben dating to the 17th century. It enabled the rafting of timber for the mining and smelting industries in the Ore Mountains of eastern Germany. It ran from the River Flöha near Fleyh (Fláje) to the Freiberger Mulde near Clausnitz in the Ore Mountains.
Starting at Fleyh this artificial water channel ran for about 3.5 km in a northwesterly direction to the eastern end of Bohemian Georgenthal (today Český Jiřetín). Here it changed direction by almost 180° and ran for about 3 km eastwards into the Rauschenbach valley. After crossing the Rauschenbach stream and the Bohemian-German border it continued towards the west. North of Cämmerswalde it crossed the watershed between Flöha and the Freiberger Mulde rivers. From there on the ditch ran in a northerly direction through Clausnitz and discharged finally after about 18 km at the southeastern end of Clausnitz into the River Rachel.
Shortly behind Fláje the ditch crosses a steep hillside and the channel is hewn out of the rock. The channel also crosses several streams en route to Clausnitz, for example, it crosses the Rauschenbach after about 6.5 km and the Czech-German border that runs along it here.
The channel was dug in the years 1624–1629 at the instigation of the lords of Lobkowicz in Bohemia and Schönberg in Saxony. It was commissioned by the Saxon prince-elector, John George I. By 1569 the Saxon chief mining engineer (Oberbergmeister), Martin Planer, had produced the first plans for a rafting channel from the source region of the River Flöha to the Freiberger Mulde, which had to cross the watershed of both river catchment areas. But the Neugrabenflöße was not built until the 17th century to new plans by chief smelting officer (Oberhüttenverwalter), Friedrich Lingke.
