The Zoommeer is a freshwater lake situated in eastern Zeeland, lying south of Tholen and west of Bergen op Zoom. It occupies the site of the historically drowned land of Reimerswaal and covers a protected area of 1,053 hectares, designated under the Natura 2000 network.

The lake was formed through the construction of two major water management structures: the Oesterdam and the Markiezaatskade. It forms part of the Scheldt-Rhine Canal, a tide-free shipping corridor connecting the ports of Antwerp and Rotterdam, as well as routes extending into Germany. This canal is rated for vessels up to CEMT class VIb, meaning paddlers should be aware of significant commercial shipping traffic on and around the lake. On the western side, the Bergse Diepsluis connects the Zoommeer to the Oosterschelde, though this passage is rated only CEMT class 0. The Theodorushaven in Bergen op Zoom is accessible via the Burgemeester Peterssluis for vessels up to CEMT class V. The lake also connects directly to the Krammer/Volkerak via the Scheldt-Rhine Canal.

A persistent and significant water quality concern for paddlers is the recurring growth of blue-green algae (cyanobacteria), which has been problematic for years. Blue-green algae can pose serious health risks to humans and animals through skin contact or ingestion, and paddlers should check local advisories before any outing on the Zoommeer.

Given the lake's role as part of an active international shipping route, paddlers need to exercise considerable caution regarding large vessel traffic. The combination of commercial shipping, the scale of the waterway, and ongoing water quality issues makes this a technically and safety-conscious destination rather than a straightforward recreational paddle.
