The Hochspeyerbach is a 21 km (13 mi) long river in the Palatinate forest in Rhineland-Palatinate and a left tributary of the Speyerbach.

In earlier times the river was dammed about 200 m (660 ft) from the source, and this reservoir was the swimming pool.

The water of the newly reconstructed habitat spring pond is fed into a pipe system by an overflow drain.

At the entrance to Frankenstein, it takes up the Glasbach from the left, coming from the Diemerstein Valley.

After the confluence with Fischbach, it was straightened, to enable timber rafting, and the banks were consolidated.
