The HRB Eseltal is a flood retention basin in the Eseltal near Söhnstetten in the Heidenheim district in Baden-Württemberg .

The dammed, only periodically water-bearing and on long stretches even bedless body of water is the Eseltalgraben, which unites below Söhnstetten with the Mauertalgraben to the Wedel.

description

The structure seals off the approximately 4 km long Eseltal dry valley, which begins near the village of Steinenkirch in Böhmenkirch and to which only the shorter, also dry Ulmer Valley and, shortly before the dam, the approximately 2.5 km long Benzenhauser Teich dry valley from the outskirts of Böhmenkirch runs in. The catchment area is about 11.5 km². It is located on the karstified white Jura plateau of the Swabian Alb in the Albuch natural area .

The barrier, built in 1956, is about 0.8 km west of the outskirts of Söhnstetten and has a 12.6 m high earth dam , the crown of which is up to 587.5  m above sea level. NHN is enough. This can hold back up to 286,000 m² of water. The flowing Mauertal ditch joins a little below the village with the left Eseltal ditch to the Wedel , which flows as the crow flies about 11 km further east in Heidenheim from the right into the Brenz . Measured against its 218 km² surface catchment area, the frond usually carries little water.

Water association

The retention basin is operated by the Wedel-Brenz water association.
