Bigge Reservoir

In the Bigge Reservoir, diving is permitted at the Kraghammer Sattel (notifiable), at the Lake Bigge diving school (only for training purposes) and in the diving site Weuste (without prior notification). In times of maximum storage, the lake is up to 42 metres deep at the Kraghammer Sattel. The diving site Weuste with a maximum depth of 23 metres is also suited for beginners due to its shallow entry.

Henne Reservoir

The diving site of the Henne Reservoir is situated on the western bank next to the small marina. Diving is organised by the guard of the DLRG, the German life saving society, which can be found in the Berghauser bay. The guard issues licences upon prior reservation. The number of divers, their club memberships, a telephone number and the exact date must be specified in advance in order to obtain a licence.

Möhne Reservoir

The diving site of Lake Möhne is situated on the southern bank, west of the Delecke Bridge in the Delecke Bay. The diving area - a former quarry with a sandy ground - is defined by buoys. Diving is not allowed outside the designated area. The piers of the Delecke Bridge do not form part of the diving site. From the car park, which tends to be very frequented especially during the summer months, a path leads along the edges of the quarry to two possible entry spots. Dives in the Möhne Reservoir have to be registered with the DLRG Westphalia state division, specifying the number of divers and the date.
