Assessing Residents' Knowledge, Attitudes, and Values Towards the Duluth Urban Deer Herd
(2015-05) Timmerman, Ryan
The purpose of this exploratory quantitative mail survey was to discover Duluth residents’ knowledge, attitudes, and values towards the urban deer herd. An area based purposive sample was drawn and the households selected were mailed a four-part questionnaire. The sample was comprised of households in 5 of Duluth’s 34 Deer Hunt Areas (DHAs) which had been created by the Arrowhead Bowhunters Alliance (ABA). With a 32% return rate (150 surveys returned of 469 viable sent), surveys found: scores of; 64% correct on factual deer knowledge; personal experiences, family, and friends were the most common sources of knowledge; personal perceived knowledge was higher than the perceived knowledge of others; overall attitudes and values were positive towards deer; and communication benefits were the most important attitude and values topic. From these results, it was found that factual knowledge was low, self-initiated sources of knowledge were most common, residents’ perceived knowledge was higher than factual knowledge, and naturalistic attitudes were the highest while deer tolerance and educational values were the lowest. From these results, the following recommendations were made: schools could create more lessons revolving around deer in all subject matters to increase knowledge; nature centers and ELC’s could create more programs concentrating on deer to increase positive attitudes and values towards them; government agencies could use their position for outreach campaigns revolving around deer to reach a large amount of people; and the City of Duluth and the ABA could use the results of this survey to help create a management plan for the urban deer herd.
Conservation Design Toolkit for LakeSuperiorStreams.org Stormwater Pollution Prevention Pilot Project

Duluth, Minnesota has 43 named streams, 12 trout streams, and borders both pristine Lake Superior and the Duluth-Superior-Harbor Area of Concern. Duluth's storm water infrastructure includes 93 miles of streams and wetlands, and urbanization and rural development impact these waters by increasing runoff and velocity, temperature, turbidity and sediment, road salt, organic matter and nutrients. In 2002, an EPA (Environmental Monitoring for Public Access & Community Tracking) grant established a Partnership called DuluthStreams between the City of Duluth, University of MinnesotaDuluth professionals at the Natural Resources Research Institute and Sea Grant Program, and the Minnesota Pollution Control Agency and Western Lake Superior Sanitary District. Their goal was to enhance public understanding of streams and their connections to watershed land use by using real-time data and interpretive materials to illustrate the nature and consequences of degraded stormwater and its real costs to society. This has included issues associated with too much runoff such as flooding, with a key issue in the region being sanitary sewer overflows from infiltration and inflow (I&I). These events have imposed risks to public health and environmental risks to the coastal zone of Lake Superior and the Duluth-Superior Harbor, and required costly programs to reduce stormwater flows from key neighborhoods and construct storage tanks for temporary storage of stormwater enhanced sanitary sewer flows. The consequences of excess water and peak flows have also included excess sediment and turbidity, and potentially excess nutrients and pathogens. High salt concentrations for significant periods in late winter and early spring runoff from winter road and parking lot de-icing can present additional stress to trout and their prey. Increasing impervious surface and direct and indirect removal of riparian vegetation increases peak temperatures, especially during base flow periods creating additional periods of stress to cold water species with the additional potential stress of lowered dissolved oxygen. In 2003, sixteen governments and groups in the North Shore Region joined to form the Regional Stormwater Protection Team (RSPT). The Team's mission is to protect and enhance the region's shared water resources through stormwater pollution prevention by providing coordinated educational programs and technical assistance. One of the vehicles that the RSPT has harnessed for its stormwater education campaign is the DuluthStreams website as part of a regional effort to provide water pollution information to the public. The project has now expanded to now include 22 communities, agencies and organizations. In 2005 the website was re-named lakesuperiorstreams.org to reflect the broader geographic region that it represents in terms of climate, soils, quality of life, natural resources, the Lake Superior watershed, and culture. The website now averages more than 300,000 "hits"/month and >75,000 "page requests"/mo with a national target audience that includes: the general public; students and teachers; contractors, consultants and developers; decision makers; and agencies (local, state, and federal). Additional information is best found by examining http://lakesuperiorstreams.org.
Duluth Area Lakes Water Quality Assessment: Caribou, Grand, and Pike Lakes - 1999; Pike Lake Fall Overturn Studies - 1996-1998
(University of Minnesota Duluth, 2001) Anderson, Jesse; Heiskary, Steven; Axler, Richard P; Henneck, Jerald
Minnesota is divided into seven regions, referred to as ecoregions, as defined by soils, land surface form, natural vegetation and current land use. Since land use affects water quality, it has proven helpful to divide the state into regions where land use and water resources are similar. Data gathered from representative, minimally-impacted (reference) lakes within each ecoregion serve as a basis for comparing the water quality and characteristics of other lakes. Caribou, Grand, and Pike Lakes are located on the northern edge of the Duluth Metropolitan Area (Figure 1) in the Northern Lakes and Forests Ecoregion (Figure 2). Caribou Lake has an area of 569 acres (230 hectares), and a maximum depth of 21 feet (6.4 meters). The majority of the lake is less than 10 feet deep, and is dominated by emergent and submergent aquatic vegetation. Grand Lake has an area of 1742 acres (705 ha). Baby Grand Lake flows into Little Grand, which flows into Grand Lake. Similar to Caribou, much of Grand Lake (~ 95%) is less than 10 feet (3 m) deep, and vegetation dominates the shoreline and near-shore areas. Pike Lake has an area of 508 acres (206 ha), and is much deeper. The maximum depth is 60 feet (~18 m), and most of the lake is between 20-50 feet deep (6-15 m). These lakes all have relatively developed shorelines and are likely to experience increased development pressure in the next decade. They have also experienced some degree of water quality problems in the past. Efforts are underway to improve wastewater treatment on two of these lakes. Construction of a sanitary sewer was recently (1999) begun around Pike Lake, and a constructed wetland wastewater treatment system servicing a cluster of nine (9) lakeshore homes was installed at Grand Lake in late 1995. The present study was conducted because local units of government desired additional water quality information on these Duluth area lakes for planning purposes. The Pike Lake Association also desired some follow-up work for comparison to a previous MPCA study (Bauman 1994), and to better define current lake water quality prior to the installation of a sanitary sewer in the basin.
Duluth Residential Stormwater Reduction Demonstration Project for Lake Superior Tributaries
(University of Minnesota Duluth, 2011) Kleist, Chris; Brady, Valerie; Johnson, Lucinda B; Schomberg, Jesse
We used paired 2‐block street sections in the Amity Creek watershed (Duluth, MN) to demonstrate the effectiveness of homeowner BMPs to reduce residential stormwater flow to storm sewers in an older neighborhood in a cold climate on clay and bedrock geology. Runoff from each street was measured before and after installation of stormwater BMPs. In addition, the knowledge, attitudes, and practices of residents were measured before and after BMP installation. BMPs were installed on properties of willing residents of one street (“treatment”). Most residents (22 of 25 properties) willingly participated. 250 trees and shrubs were planted; 22 rain barrels were installed; 5 rain gardens, 12 rock‐sump storage basins, and 2 swales were constructed; and a stormwater ditch was re‐dug and had 5 ditch checks installed in it. The post‐project survey indicated an increase in understanding by treatment‐street residents of where stormwater flowed to and what it affected, and an increase in willingness to accept at least some responsibility for stormwater runoff. Residents who received BMPs were generally satisfied with them and would recommend them to others. Runoff reduction proved more difficult to quantify due to high and inconsistent runoff variability between the paired streets, very few pre‐BMP installation rain events, and loss of one control street due to re‐paving mid‐project. Capacity of installed BMPs is approximately 2.5% of the measured stormwater runoff. There is about a 20% greater reduction in runoff for the treatment street after BMPs were installed than for the control street for small to moderate storm events; while we would like to attribute this completely to our BMPs, we cannot prove that other factors weren’t also at work. Peak flows also appear to have been reduced for 1 inch and smaller rainstorms, but we were unable to accurately measure this reduction. The results are available on an existing stream education website and are used to educate neighborhood, city of Duluth, and regional residents on stormwater issues, individual responsibility, and BMP options.

Duluth Values Open Space
(2002) Kreag, Glenn M
This report documents how residents perceive the importance of open spaces in Duluth, Minnesota. While not specifically about water resources, this study refers occasionally to the value of wetlands, lakes and rivers. Key findings of the survey are extracted and reproduced below. Executive summary: “Duluth is known for its extensive open spaces, particularly their natural ambiance and relation to Lake Superior. The type, nature, and quantity of open spaces contribute significantly to the character and quality of a community, a concept captured locally in the community-wide "2001 & Beyond" visioning process (completed in 1997) where participants indicated that maintaining Duluth as an "urban wilderness" was a priority. The data in this report are the result of an 8-page, 20-question survey that reached 955 Duluth residents in 2001. The University of Minnesota Sea Grant Program designed the survey with assistance and review from the EAC, the NRI Committee, and the Minnesota Center for Survey Research. Two types of open space were defined in this study: Natural Open Space - places where the native vegetation grows without significant alteration and, Developed Open Space - places where land and vegetation are altered or controlled. Of the questions relating to water resources, 93% of those taking the survey reported that they frequently use and enjoy views of Lake Superior and the St. Louis River. 50% reported using and enjoying wetland areas. Regarding developed open spaces, 68% reported using a public access for boating and fishing. 70% of respondents felt that water supply, sanitary and storm sewers were important government functions related to open spaces.”
DuluthStreams heads north: Making North Shore stream data make sense to citizens and local officials
(University of Minnesota Duluth, 2007-09-25) Axler, Richard P; Will, Norman; Host, George E; Henneck, Jerald; Lonsdale, David; Sjerven, Gerald; Reed, Jane; Ruzycki, Elaine; Hagley, Cynthia; Schomberg, Jesse; Carlson, Todd; Lonsdale, Marnie
The Duluth Streams website initially focused primarily within City of Duluth boundaries, but some of the streams that intersect Duluth originate in the surrounding communities of Hermantown and Proctor. In addition, Duluth and Superior share the St. Louis River watershed. The current project enabled us to fully expand the DuluthStreams website into a regional entity. It was built on a previous, but limited, Lake Superior Coastal Program Enhancement Fund effort to Minnesota Sea Grant at the University of Minnesota and partners that created web links to Proctor, Hermantown and Superior on the DuluthStreams website. This made these communities ideal as the first candidates for a regional expansion. As the project continued to evolve it became clear from discussions within the RSPT and with state agencies that there was a need to expand the focus area of the website to include the “greater Western Lake Superior” region and more specifically the Minnesota North Shore and Wisconsin South Shore in order to better manage Superior Basin water resources by supporting the mission of the RSPT regarding developing regional technical cooperation and collaboration, common educational materials, and presentation of case studies of successful stormwater designs. Minnesota streams draining into the Lake Superior coastal zone and St. Louis River Estuary are typically sensitive, low productivity, high-quality trout streams. Some (Miller, Amity, Lester, Talmadge, French, Poplar, Brule) are currently listed on the MN Clean Water Act (303d) List of Impaired Waters - most commonly for turbidity and Fish-Hg (MPCA 2006). Steep topography and thin, erodible soils make these streams particularly sensitive to development. Effective management and remediation of these streams requires an understanding of their physical, chemical, and biological characteristics, which can only be obtained by monitoring, particularly during storm and snowmelt runoff events, when the most dramatic impacts occur. These data are critical for developing and assessing BMPs, particularly in the face of increased development in the high growth watersheds along the North Shore of Lake Superior (e.g. Anderson et al. 2003; MPCA 2000; IJC 1999). MPCA initiated long-term monitoring of 6 critical streams along the North Shore in 2002. However, MPCA has lacked the resources to install automated water quality sensors, which are needed to capture critical pollutant loading events during high flows - important for developing cost-effective remediation and mitigation strategies.
DuluthStreams.org: Community Partnerships for Understanding Urban Stormwater and Water Quality Issues at the Head of the Great Lakes
(University of Minnesota Duluth, 2004-12) Axler, Richard P; Lonsdale, Marion; Reed, Jane; Hagley, Cynthia; Schomberg, Jesse; Henneck, Jerald; Host, George E; Will, Norman; Ruzycki, Elaine; Sjerven, Gerald; Richards, Carl; Munson, Bruce
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.
Economic Impact of Off Road Cycling in Duluth: An Expenditures Approach
(2017) Savolt, Abby
Through the use of a survey taken by 384 people, data analysis, and IMPLAN this study quantified the extent of economic impact and satisfaction levels of Duluth mountain bike trail users. First the demographics of trail users were analyzed to conclude that the majority of riders in Duluth are male with annual income levels that varied greatly across respondents. 57% of survey respondents were between the ages of 30 and 49, and 57% ride the Duluth mountain bike trails at least once per week. Overall, Duluth mountain bike trail users are satisfied with the various aspects of the trails such as the variety of trails, bike friendly amenities, number of trails, etc. Results of this study show that mountain bikers in Duluth who ride these trails contribute $36.6 million to $48.9 million a year to the Duluth economy. This number includes an economic impact of $10.9 million to $14.5 million from local trail users and an economic impact of $25.8 million to $34.4 million from nonlocal trail users. One can see that the original estimated cost of $6.1 million to $7 million, to add an additional 70 miles to the Duluth Mountain biking trail system, is economically beneficial to the Duluth economy. The original investment is creating annual returns greater than the original costs.

An Evaluation of Homeschool Students' Interest In Science and Science Careers
(2017-03) Carlson, Anne E
This paper evaluates homeschoolers' interest in science and science careers. Studies by Phillips (2010) and Wheaton (2010) found that homeschool students do not major in natural science as frequently as non-homeschool students, or take as many, or high as level, of science courses as non-homeschool students. The purpose of this study was to determine if interest in science was a factor in homeschool students not majoring in natural science in college or taking as many science courses in high school. The study found that young homeschool students are interested in science but there was not conclusive data on whether homeschool students are interested in science careers. This paper also highlights some problems with teaching science in homeschool and provides recommendations for further research.
Exploring the Relationship between Digital Nature Photography and Children's Connectedness to Nature
(2012) Spencer, Seth F
Digital photography can be an enjoyable and exciting activity for children. It may also increase connectedness to nature levels. Questionnaires were sent to four different Duluth, MN area 4th grade classrooms. The questionnaire was comprised of the Connectedness to Nature Index (Cheng & Monroe, 2010) and one open-ended question. The questionnaire was given as a pretest and a posttest, after two of the schools participated in a program using digital cameras. Eight-five percent (n=99) responded to the questionnaire. Findings of the study revealed that the respondents generally had a strong connectedness to nature before and after their use of digital cameras. While quantitative data showed no significant change between pretest and posttest connectedness to nature levels, qualitative and anecdotal data suggested that the use of digital cameras can influence connectedness to nature levels in children. The results may be used to emphasize the importance of finding new and creative ways to connect today’s children with a sense of connectedness to nature.
Floods of June 2012 in Northeastern Minnesota
(2012) Czuba, Christiana R; Fallon, James D; Kessler, Eric W
This report is a summary description of the 2012 flooding in the Fond du Lac region of Lake Superior from a meteorological and hydrologic perspective. The report notes that the extent and depth of flooding in communities can be used for flood recovery efforts. Key points are reproduced below. Abstract: “During June 19–20, 2012, heavy rainfall, as much as 10 inches locally reported, caused severe flooding across northeastern Minnesota. The floods were exacerbated by wet antecedent conditions from a relatively rainy spring, with May 2012 as one of the wettest Mays on record in Duluth. The June 19–20, 2012, rainfall event set new records in Duluth, including greatest 2-day precipitation with 7.25 inches of rain. The heavy rains fell on three major watersheds: the Mississippi Headwaters; the St. Croix, which drains to the Mississippi River; and Western Lake Superior, which includes the St. Louis River and other tributaries to Lake Superior. Widespread flash and river flooding that resulted from the heavy rainfall caused evacuations of residents, and damages to residences, businesses, and infrastructure. In all, nine counties in northeastern Minnesota were declared Federal disaster areas as a result of the flooding. Peak-of-record streamflows were recorded at 13 U.S. Geological Survey stream gages as a result of the heavy rainfall. Flood-peak gage heights, peak streamflows, and annual exceedance probabilities were tabulated for 35 U.S. Geological Survey stream gages. Flood-peak streamflows in June 2012 had annual exceedance probabilities estimated to be less than 0.002 (0.2 percent; recurrence interval greater than 500 years) for five stream gages, and between 0.002 and 0.01 (1 percent; recurrence interval greater than 100 years) for four stream gages. High-water marks were identified and tabulated for the most severely affected communities of Barnum (Moose Horn River), Carlton (Otter Creek), Duluth Heights neighborhood of Duluth (Miller Creek), Fond du Lac neighborhood of Duluth (St. Louis River), Moose Lake (Moose Horn River and Moosehead Lake), and Thomson (Thomson Reservoir outflow near the St. Louis River). Flood-peak inundation maps and water-surface profiles were produced for these six severely affected communities. The inundation maps were constructed in a geographic information system by combining high-water-mark data with high-resolution digital elevation model data. The flood maps and profiles show the extent and depth of flooding through the communities and can be used for flood response and recovery efforts by local, county, State, and Federal agencies.”

Miller Creek Stormwater Modeling
(University of Minnesota Duluth, 2000) Schomberg, Jesse; Richards, Carl; Host, George E
The US EPA’s Stormwater Management Model (SWMM) was used to model stormwater runoff volumes and pollutant concentrations in Miller Creek, located in Duluth, Minnesota. The quantity model was calibrated and validated with two years of hourly gage data for three sites along the creek. The quality model had minimal calibration from pollutant loading data for four subcatchments, and was meant for use as a comparative tool to analyze relative changes in pollutants based on various scenarios. As expected, commercial and industrial areas with high amounts of impervious surfaces had a significant impact on the flow volumes, resulting in higher, flashier peaks than undeveloped portions of the watershed. Of the four pollutants modeled (total dissolved solids, total suspended solids, nitrate-Nitrogen, and total Phosphorus), developed areas contributed the majority of all pollutants.
