Lake Råvarpen is part of the Dalsland Canal lake system. It stretches from the power station in Dals Långed south to Buterud in its southern end. The water flow can be rather strong in northern part, especially in spring and autumn. The lake empties to the south at Buterud. To the north at Tisselskog the shore meets agricultural land, but the rest of the shoreline is for the most part rocky and forested. There is one large island named Bockön and app. 6-8 smaller islet and skerries in the lake.
Lake Råvarpen is a well-stocked, interesting lake with varied surroundings and a lovely nature. There are many perch and pike, as well as a smaller stock of large trout. Fishing here calls for a motorboat. Spin for pike and perch is both effective and fun. If you want larger pike, trolling is an excellent and popular method that can even bring in some trout as a bonus. Fishing for perch is best from mid-May through early September, while spin-fishing for pike is best between mid-April through to late in October. Trolling for large, pelagic pike is usually best from June to early October. Then there are some interesting shallows and a few sounds around the lake that can offer good fishing. The periodic currents in these sounds draw many species looking for food.
