Abstract
This final report summarizes the accomplishments of the Duluth Streams Partnership from its
inception through an EPA Environmental Monitoring for Public Access and Community Tracking (EMPACT) Program grant in January 2002 through September 2004. Duluth, Minnesota lies at the westernmost end of Lake Superior, the source and headwaters of the entire Laurentian Great Lakes ecosystem. Although perhaps better known for its extremely cold winters, Duluth residents and visitors know it as a city of forested hills, wetlands and trout streams with 42 named creeks and streams moving through the City in 30 subwatersheds. Duluth's park system is one of the most extensive in the nation, and the City owns and maintains 11,000 acres, including 125 municipal parks. Streams form the fabric of the aesthetic appeal and character of Duluth (Duluth Vision 2000), but are also the core of the City’s stormwater runoff system, with 250 miles of storm sewer, 93 miles of creek, 4,716 manholes, 2 lift stations, 13 sediment boxes, and over 138 miles of roadway ditches.
Urbanization and rural development have placed increased pressure on the region’s coastal communities and on Duluth’s urban streams, in particular, on the 12 (with 2 more pending) that are designated as Trout Streams and 14 that are classified as Protected Waters. In addition, since the early 1990s, over 50 new lodging establishments were constructed along Lake Superior’s North Shore. One county located along the North Shore of Lake Superior (Cook) experienced a 24% population increase during that time. Stream communities of fish and amphibians and the invertebrates that sustain them are being adversely impacted by increased temperature, excessive turbidity and suspended solids, road salts, organic matter, and nutrients. Some of these streams have been placed on the Minnesota List of Impaired Waters, and several have been targeted for Total Maximum Daily Load (TMDL) development. Further, all of these streams discharge either directly into ultra-oligotrophic Lake Superior or indirectly via the St. Louis River Estuary- Duluth Superior Harbor. This is particularly important because Lake Superior has been designated as a zero-discharge demonstration project by the International Joint Commission for eliminating inputs of persistent toxic chemicals to the Great Lakes system. Second, the lake’s nearshore zone, the source of much of its biological productivity, is extremely nutrient deficient and sensitive to increased inputs of nutrients, suspended solids, turbidity, and organic matter. Lastly, the Harbor itself is one of the 43 Great Lakes Areas of Concern (AOCs) because of serious impairments to its beneficial uses. There are also significant social and economic impacts associated with this region - the Minnesota DNR reports that angling in North Shore streams and Lake Superior produces $63 million in direct sales and income and over 1,200 jobs. For North Shore streams alone, the numbers are over $33 million direct sales and income, and over 435 jobs.
Stormwater issues have become increasingly important to resource and regulatory agencies and to the general public. In 1998 the City of Duluth established a stormwater utility to address the quality and quantity of surface water moving through the City and in 2003 was issued a Stormwater Permit under Phase II of the federal Clean Water Act’s National Pollution Discharge Elimination System (NPDES). Beginning in January 2002, under funding through EPA EMPACT in combination with in-kind effort from various agencies, the Natural Resources Research Institute (NRRI) and Minnesota Sea Grant formed a partnership with the City of Duluth, the Minnesota Pollution Control Agency (MPCA), the Great Lakes Aquarium, and the Western Lake Superior Sanitary District (WLSSD) to create Duluth Streams. Additional partners
have since joined together to form a Regional Stormwater Protection Team (RSPT). The Partnership's chief goal is to enhance the general public's understanding of aquatic ecosystems and their connections to watershed land use to provide both economic and environmental sustainability.
The project’s majors objectives were to: 1) link real-time remote sensing of water quality in four urban streams and GIS technology to current and historical water quality and biological databases (all 42 Duluth streams) using advanced data visualization tools in World Wide Web and information kiosk formats; 2) incorporate visually engaging interpretive text, animations and videos into the Duluth Streams website to illustrate the nature and consequences of degraded stormwater and the real costs to society; and 3) engage the public in the stormwater issue via programmatic activities such as establishing high school directed neighborhood stewardship and/or monitoring of 3 streams, developing curricula for high school and college students for inclusion in our Water on the Web curriculum, hosting a Duluth Streams Congress as a community forum for presenting all project results, and adapting the Nonpoint Education for Municipal Officials (NEMO) program to the greater Duluth Metropolitan Area.
This final report summarizes the accomplishments of the Duluth Streams Partnership from its inception in January 2002 through September 2004. The website at htttp://duluthstreams.org is the focus of the project and offers water quality, biological, and GIS data in the context of a variety of school- and community-oriented educational material.
