Mirror Pond is a piece of city history and a misnomer all in one. Presently, the ironically murky waters of the Manito Park pond are hardly clear enough to catch a glimpse of one’s reflection. Flash back 60 years, though, and the water feature was a natural lake with extended shorelines, used for canoeing and ice skating. The Friends of Manito, raising money for a big renovation project, already has reached two-thirds of its $305,000 goal. This weekend, the park’s booster nonprofit hosts a catered picnic dinner and silent auction, including a beer/wine garden by No-Li Brewhouse, and live music through the night. It’s a summer celebration that could restore the pond to its former glory — clean, reflective, and worthy of its name.
