Collaborating to Care for Lake Winnisquam
2026 Lake Winnisquam Drawdown
NH Department of Environmental Services announced the schedule for the fall 2026 Lake Drawdowns. The drawdown of Lake Winnisquam, which occurs on a two-year interval, lasts only approximately two weeks. The lake will be drawn down two feet below its normal full pond level and is coordinated with the drawdown of Lake Opechee. The lowering of Lake Opechee will begin on October 12, and it will likely take two days to pass the water from Opechee downstream through Lake Winnisquam. The level of Lake Winnisquam is expected to drop noticeably on October 14. On October 26, flows at Lakeport Dam will be increased to refill Lake Opechee, and the level of Winnisquam should begin to rise late in the day on October 27.
