Grays Bay Dam offers a unique freshwater drift snorkel experience where Lake Minnetonka flows into Minnehaha Creek. This artificial reef site features a shallow depth profile ranging from 2 to 9 metres, with an average depth of 4 metres. The site is suitable for beginners, though snorkelers should be aware of potential down currents near the dam structure. Entry is via the shore, and parking is available for visitors. Water temperatures can be cold, particularly during spring and autumn, making a wetsuit recommended for comfort and safety. The current is generally mild, allowing for a relaxed drift through the area.
