Wreknball's Hollow (Canyon Ferry Lake)

Wreknball's Hollow at Canyon Ferry Lake is a small-lake windsport launch on the eastern shore known for clean water and generally strong, frontal-driven winds. On-water conditions are commonly flat to choppy, which makes it well suited to freeride styles and, when conditions are right, foil use. Most favorable on-water season runs from late April to early October. Early and late season typically call for a drysuit/wetsuit, while mid-season can be comfortable in shorts or a shorty. Wind is described as primarily frontal/gradient, with thermal effects that can strengthen conditions during summer afternoons—often producing the strongest winds from late morning into early evening. The launch area itself is the main challenge: it’s described as a narrow, rocky shoreline with limited space for rigging and launching. With cold water temperatures across much of the year and hazards like rocks and potential submerged debris near the edges, riders should plan for intermediate-level conditions and be prepared to manage hypothermia risk. Rescue support is limited (no dedicated kite/windsurf rescue services), so riders are expected to be self-sufficient and to follow standard right-of-way with awareness of fishing boats and other lake users. Overall, it’s a low-profile, community-known spot that rewards riders who can handle rocky access and colder water while leveraging consistent wind in the May–June and September–October windows.
