    Longfellow's epic poem "Song of Hiawatha" popularizes area
    Henry Wadsworth Longfellow’s epic poem “Song of Hiawatha” makes Minnehaha Falls famous and a tourist destination.
    An excerpt:
    In the land of the Dacotahs,
    Where the Falls of Minnehaha
    Flash and gleam among the oak-trees,
    Laugh and leap into the valley.
    There the ancient Arrow-maker
    Made his arrow-heads of sandstone,
    Arrow-heads of chalcedony,
    Arrow-heads of flint and jasper,
    Smoothed and sharpened at the edges,
    Hard and polished, keen and costly.
    With him dwelt his dark-eyed daughter,
  • First resort opens along Lake Minnetonka

  • Dam built on Gray's Bay

    Dam built on Gray's Bay
    Dam built on Gray’s Bay to control water levels of the lake and creek. Hennepin County condemned the Minnetonka Mill after the owner would not sell and moved it 2.5 miles upstream. The dam slowed the creek and effectively shut down all downstream mills (like Richfield and Edina), which couldn’t compete with those tapping into St. Anthony Falls in downtown Minneapolis.
  • Big Island Amusement Park

    Big Island Amusement Park
    An amusement park is built on Lake Minnetonka’s Big Ilsand, featuring a 200 foot water tower. It would be closed by 1911.
  • Watershed District Act passed by Minn. Legislature

    Recognizing the value of Minnesota waterways and surrounding natural areas, the Minnesota Legislature passes the Watershed District Act, authorizing the creation of local government units called watershed districts. The districts were created to help manage the entire land area from which rain and snowmelt drain to lakes, streams, or wetlands. As outlined by the Act, watershed districts use scientific principles to develop successful ways to manage and improve water quality, prevent flood damage
  • Minnehaha Creek flooding in Minneapolis

    An ice-choked Minnehaha Creek floods Minneapolis neighborhoods, spurring interest in a Minnehaha Creek Watershed District.
  • MCWD established

    MCWD established by Hennepin and Carver Counties. Their goals included improving lakes, marshes and channels for water storage, drainage, recreation and other public purposes. The counties also wanted projects to reduce flooding, to keep silt out of streams and to control erosion of land. Other goals were reclaiming wetlands, controlling stormwater and preserving water quality in the District’s lakes and streams. The watershed consists of 181 square miles located in all or portions of 27 cities
  • Groundbreaking wetland study

    Groundbreaking wetland study
    MCWD completes a groundbreaking, federally-funded wetland study to evaluate how well wetlands treat urban stormwater runoff. The results were published by the U.S. EPA and became a national guidance document used in managing urban stormwater runoff. A 7-acre wetland in Wayzata with a 70-acre drainage area was used for the study. It retained 77 percent of all phosphorus and 94 percent of total suspended solids during the evaluation period, showing the effectiveness of wetlands.
  • Gray's Bay Improvement

    Gray’s Bay is improved at the request of five downstream communities with flooding issues. An outlet control structure was added to release water at a controlled rate from May to November. The District also added a paved parking lot, picnic facilities, toilets, bike racks and a canoe landing.
  • Recreational improvements along the creek

    Recreational improvements along the creek
    MCWD completes recreational improvements along the creek, constructing canoe landings, parking areas, picnic and sanitary facilities, bike racks, wildlife ponds, and more.
  • Closing of sewage treatment plants

    MCWD finishes closing eight sewage treatment plants that emptied 3 million gallons of treated wastewater into Lake Minnetonka per day, all replaced by the Blue Lake Treatment Plant in Shakopee. This meant about 33,000 fewer pounds of phosphorus in the lake each year.
  • Gleason Creek Improvement Project

    MCWD finishes the Gleason Creek Improvement Project, building a new outlet control structure on Gleason Lake, a stormwater pond, and enhancing a wetland at the inlet to the lake. The project significantly improved flood control on Gleason Lake and improved water quality in Lake Minnetonka.
  • Chain of Lakes Partnership

    Chain of Lakes Partnership
    MCWD undertook this long-term project in partnership with the city of St. Louis Park, the city of Minneapolis, and the Minneapolis Park and Recreation Board (MPRB) to improve the water quality in the Minneapolis Chain of Lakes. The project specifically focused on stormwater management in the Twin Lakes Subwatershed to improve the water quality of Cedar Lake. Project description
  • Wetland Restoration at Minnesota Landscape Arboretum

    Wetland Restoration at Minnesota Landscape Arboretum
    MCWD helps restoring a wetland at the Minnesota Landscape Arboretum. The site’s hydrology was restored by breaking the network of drain tiles below the soil surface. Native plant species were planted in the wetland basin and a boardwalk and interpretive trail constructed within the basin to provide access to the 20-acre wetland for close viewing and plant identification.
  • Southwest Lake Calhoun Wetland Ponds Project

  • Minnehaha Creek Methodist Hostpial Re-Meander

    Minnehaha Creek Methodist Hostpial Re-Meander
    The District returns a stretch of Minnehaha Creek in St. Louis Park to its natural meander, reversing nearly a decade of industrial straightening of the creek. The project re-meandered the creek, restored habitat, and added a boardwalk and walking trail. Research shows that patients recover more quickly when they are able to experience the outdoors while healing.
  • Big Island Restoration

    Big Island Restoration
    In 2008, the City of Orono, the state and MCWD pitched in to buy the 56-acre eastern third of Big Island. The partners decided to return the portion of the island to a passive, natural state for the public to enjoy. The District worked to restore about 3,000 feet of severely eroded shoreline to enhance water quality in Lake Minnetonka. Project description
  • Cold Storage Purchase

    Cold Storage Purchase
    The District makes a landmark purchase of a 17-acre property in Hopkins that sits along 1,000 feet of shoreline in one of the most degraded sections of Minnehaha Creek. MCWD plans to restore the shoreline, intercept runoff before it enters the creek, and open up the area to the public. It will demolish the existing building and sell a bulk of the land for re-development.
  • Master Water Steward Program Begins

    Master Water Steward Program Begins
    MCWD, in partnership with the Freshwater Society, begins a new clean water educational resource for local communities: The Master Water Stewards program. In addition to educating their neighbors about reducing runoff, the Master Water Stewards work on runoff prevention projects, such as rain gardens and water-permeable driveways. They also coordinate community activities such as leaf and grass clean-ups to reduce runoff.
  • Six Mile Marsh Prairie Restoration

    Six Mile Marsh Prairie Restoration
    Halsted Bay water quality is among the worst in the District due in part to excessive nutrients. To improve water quality in the area, MCWD purchased the 112-acre Halverson and 97-acre Dimler farms in Minnetrista, which drain into Six Mile Marsh and Creek shortly before they enter Halsted Bay. The District restored prairie and oak savanna to reduce the amount of polluted runoff entering Halstead Bay. Project description
  • Historically High Water Levels

    The wettest Twin Cities spring on record caused historically high water levels on lakes and streams across the Minnehaha Creek Watershed District. Lake Minnetonka reached an all-time high of 931.11 feet above sea level on Monday, June 23 and spent 45 consecutive days above the pre-2014 all-time high of 930.52.
