The lake stretches approximately 70 km (43.5 Mi) from Ed in the south past Nössemark to Töcksfors in the north, on Lake Foxen. It is a narrow lake, rarely measuring more than 2 to 3 km across, apart from a stretch forming part of Lake Foxen, where it reaches a full 5 km. Stora Le and Lake Foxen combined cover 131 km2. This makes Stora Le the 19th largest lake in Sweden. Its greatest depth is 99 metres to the south of Västra Fågelvik in the Lake Foxen part.
The lake system's level has been controlled since 1945 when the level was raised by 6 dm (2 ft) to 102.1 m (335 ft) above sea level. Lake levels are allowed to vary within a 1-metre bandwidth. The maximum allowed outtake of water is 80 cubic metres per second. The lake is reachable by boat through the Dalsland Canal. The lake's shores are mountainous and the forest nearly grows down to the water line. Dalsland's provincial fish the fourhorn sculpin is also found in Stora Le.
The islet of Trollön (Troll's island, Trolløya in Norwegian) is situated on the Norway–Sweden border, which divides the island in two.
