Irenensee, Artificial lake in Uetze, Germany.

Irenensee is an artificial lake in the Hanover region that spans a large water surface. The area has gentle shorelines and is surrounded by green meadows and trees, making it well-suited for various outdoor activities.

Farmer Friedrich Meinecke dug out the lake and the adjoining Spreewaldseen from 1971, naming the lake after his wife Irene, who came from Dahrenhorst. He turned to building the lakes and running a campsite after the Burgdorf canning factory closed and he could no longer sell his vegetables. The road leading to the lake is named Fritz-Meinecke-Weg after him.

The lake is named after Irene, the wife of farmer Friedrich Meinecke, who dug it from 1971; the access road is called Fritz-Meinecke-Weg after him. The Spreewaldseen next door, with weekend houses and boat jetties, are named after the Spreewald in Brandenburg and were converted from a weekend colony into a residential area around 2010.

The lake lies on the B 188 in Uetze, with the Schilfbruch nature reserve to the west and the Fuhse-Auwald to the north. A 160-metre sandy beach is the designated bathing area; swimming, surfing, sailing and paddling are allowed on the water. A snack bar, restaurant and kiosk serve visitors, and accommodation ranges from camping to holiday houses and mobile-home pitches.
