Lake Rørbæk is fed by the Skjern River, which rises 2.5 km southeast of the lake. Kulsø lies slightly west of Lake Rørbæk. Lake Rørbæk was formed in a dead-end sinkhole in the Tunnel Valley. Sand and gravel deposited in the dead ice formed several small islands, most of which are merely elevations on the lakeshore. [2] On the eastern part of the Kælderbanke ridge, south of the lake, there is a 15 × 6 m cellar, 1.5 m deep, made of boulders. [3] These are the remains of the Gammel Rørbæk farmstead, which was burned down by Swedish troops in 1657 during the First Charles Gustav War and was not rebuilt. [ 1 ] A few hundred meters south of Kælderbanke lies Ballesbækgård, where there is a small museum. [ 1 ] The lake forms the border between the municipalities of Ikast-Brande and Vejle.
