Otto-Maigler-See

Hürth · Surrounding area of Cologne

Swimming lake formed in a former brown coal pit near Hürth, purpose-built with six side-by-side regatta lanes for international races and water sports.

Bathing

The Otto-Maigler-See formed after brown coal extraction ended, as incoming groundwater filled a planned open-cast mining pit. It is one of the five approved bathing lakes in the Rhein-Erft district and was designed to accommodate six parallel regatta lanes.

Water area comparison

Water area compared with other lakes in Cologne.

Origins and Design

The reclamation plan traces back to the groundwork of Cologne landscape architect Victor Calles, who worked on rehabilitating the mining areas from 1946 and drew up a concrete plan for the site in 1961. The pit was originally divided by three clay ridges, which were removed to merge the areas into a single large lake, with a sandy bathing beach added on the north-west shore. A triple row of protective planting shields the surrounding farmland from westerly and south-westerly winds. The area is a designated landscape conservation zone and forms part of the Naturpark Rheinland.

The Name

Hürth's municipal council named the regatta lake in 1967 after Otto Maigler, the recently deceased director of Roddergrube AG. As a board member of Rheinbraun, Maigler had championed reforestation and land reclamation, and was involved in planning the resettlement of the Berrenrath district.

Wildlife and Flora

The lake serves as a staging and wintering site for various duck species and mute swans; cormorants and goldeneyes appear occasionally. As an angling water it is stocked with eel, pike, carp, tench, pike-perch, perch, and coarse fish. Protected plant species recorded include pondweeds and rigid hornwort. The shallow depth means wind keeps the water circulating year-round.

Swimming and Water Sports

Stiftung Warentest rated the lake a recommended bathing water in 2008; during the swimming season the public health office tests the water for compliance with EU directives and bathing water regulations. Feeding the birds is prohibited, and aquatic vegetation is regularly trimmed by a mowing machine nicknamed the Seekuh ("lake cow"). A lido with a restaurant sits on the shore, hosting events on summer evenings. The Hürther Rudergesellschaft, founded in 1979, regularly stages international regattas on the parallel lanes, operating a boathouse above the eastern shore; the eastern section also serves as a surfing area.

Getting There

Visitors from Cologne can reach the lake via Berrenrather Straße and the cycle paths running through the Cologne Green Belt. A circular walking trail signposted from Alt-Hürth encircles the lake; the lido has a car park and is served by the Hürth local bus.
