We have a spectacular new indoor and outdoor facility for events with small groups to large groups. The newly refurbished Three Waters Reserve Event Center overlooks the scenic Sugar River Valley in rural Green County Wisconsin. From our main hall and spacious decks and grounds, one can glimpse the River and wooded bluffs above Decatur Lake, hear the distant roar of the dam, and be mesmerized by the waving expanse of restored prairie and majestic oaks that have occupied the surrounding slopes of the property for more than a century.
