Background
Big Island is a large isolated island on the Lower Lake portion of Lake Minnetonka. The island is partially developed with single-family homes and otherwise is largely preserved in parks owned by the city of Orono, Three Rivers Park District, and the Minnehaha Creek Watershed District (MCWD). The restoration work on Lake Minnetonka’s Big Island shows what can happen when local and state agencies cooperate with a similar vision. In 2008, the City of Orono, the state and MCWD pitched in to buy the 56-acre eastern third of Big Island, which had spent the previous eight decades as a state-owned campground for veterans and was the site of a theme park in the early 1900s. Without the purchase, the land would’ve likely been developed into nine private residential home sites.The partners decided to return the portion of the island to a passive, natural state for the public to enjoy, and asked MCWD to hold the conservation easement that limits new buildings and bans motor vehicles, new developments, and organized events.The District worked to restore about 3,000 feet of severely eroded shoreline to enhance water quality in Lake Minnetonka, using a variety of techniques that include riprap, bio rolls and coir block, live stakes, brush mattresses, wetland seeds, plugs, and one-inch caliper trees. It also removed buckthorn and helped clear the island of about 150 tons of garbage.
