The Lake Michigan Natural Division Characteristics
The Lake Michigan Natural Division Characteristics Lake Michigan is a dynamic deepwater oligotrophic ecosystem that supports a diverse mix of native and non-native species. Although the watershed, wetlands, and tributaries that drain into the open waters are comprised of a wide variety of habitat types critical to supporting its diverse biological community this section will focus on the open water component of this system. Watershed, wetland, and tributaries issues will be addressed in the Northeastern Morainal Natural Division section. Species diversity, as well as their abundance and distribution, are influenced by a combination of biotic and abiotic factors that define a variety of open water habitat types. Key abiotic factors are depth, temperature, currents, and substrate. Biotic activities, such as increased water clarity associated with zebra mussel filtering activity, also are critical components. Nearshore areas support a diverse fish fauna in which yellow perch, rockbass and smallmouth bass are the more commonly found species in Illinois waters. Largemouth bass, rockbass, and yellow perch are commonly found within boat harbors. A predator-prey complex consisting of five salmonid species and primarily alewives populate the pelagic zone while bloater chubs, sculpin species, and burbot populate the deepwater benthic zone. Challenges Invasive species, substrate loss, and changes in current flow patterns are factors that affect open water habitat. Construction of revetments, groins, and landfills has significantly altered the Illinois shoreline resulting in an immeasurable loss of spawning and nursery habitat. Sea lampreys and alewives were significant factors leading to the demise of lake trout and other native species by the early 1960s. -

AN OVERVIEW of the GEOLOGY of the GREAT LAKES BASIN by Theodore J
AN OVERVIEW OF THE GEOLOGY OF THE GREAT LAKES BASIN by Theodore J. Bornhorst 2016 This document may be cited as: Bornhorst, T. J., 2016, An overview of the geology of the Great Lakes basin: A. E. Seaman Mineral Museum, Web Publication 1, 8p. This is version 1 of A. E. Seaman Mineral Museum Web Publication 1 which was only internally reviewed for technical accuracy. The Great Lakes Basin The Great Lakes basin, as defined by watersheds that drain into the Great Lakes (Figure 1), includes about 85 % of North America’s and 20 % of the world’s surface fresh water, a total of about 5,500 cubic miles (23,000 cubic km) of water (1). The basin covers about 94,000 square miles (240,000 square km) including about 10 % of the U.S. population and 30 % of the Canadian population (1). Lake Michigan is the only Great Lake entirely within the United States. The State of Michigan lies at the heart of the Great Lakes basin. Together the Great Lakes are the single largest surface fresh water body on Earth and have an important physical and cultural role in North America. Figure 1: The Great Lakes states and Canadian Provinces and the Great Lakes watershed (brown) (after 1). 1 Precambrian Bedrock Geology The bedrock geology of the Great Lakes basin can be subdivided into rocks of Precambrian and Phanerozoic (Figure 2). The Precambrian of the Great Lakes basin is the result of three major episodes with each followed by a long period of erosion (2, 3).

Status and Extent of Aquatic Protected Areas in the Great Lakes
Status and Extent of Aquatic Protected Areas in the Great Lakes Scott R. Parker, Nicholas E. Mandrak, Jeff D. Truscott, Patrick L. Lawrence, Dan Kraus, Graham Bryan, and Mike Molnar Introduction The Laurentian Great Lakes are immensely important to the environmental, economic, and social well-being of both Canada and the United States (US). They form the largest surface freshwater system in the world. At over 30,000 km long, their mainland and island coastline is comparable in length to that of the contiguous US marine coastline (Government of Canada and USEPA 1995; Gronewold et al. 2013). With thousands of native species, including many endemics, the lakes are rich in biodiversity (Pearsall 2013). However, over the last century the Great Lakes have experienced profound human-caused changes, includ- ing those associated with land use changes, contaminants, invasive species, climate change, over-fishing, and habitat loss (e.g., Bunnell et al. 2014; Smith et al. 2015). It is a challenging context in terms of conservation, especially within protected areas established to safeguard species and their habitat. According to the International Union for Conservation of Nature (IUCN), a protected area is “a clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associat- ed ecosystem services and cultural values” (Dudley 2008). Depending on the management goals, protected areas can span the spectrum of IUCN categories from highly protected no- take reserves to multiple-use areas (Table 1). The potential values and benefits of protected areas are well established, including conserving biodiversity; protecting ecosystem structures and functions; being a focal point and context for public engagement, education, and good governance; supporting nature-based recreation and tourism; acting as a control or reference site for scientific research; providing a positive spill-over effect for fisheries; and helping to mitigate and adapt to climate change (e.g., Lemieux et al. -
Enormous Carnivores, Microscopic Food, and a Restaurant That's Hard to Find
Enormous Carnivores, Microscopic Food, and a Restaurant That's Hard to Find MARK F. BAUMGARTNER, CHARLES A. MAYO, AND ROBERT D. KENNEY April 1986 Cape Cod Bay We'd known for a long time that there were places east of Cape Cod where pow+l tidal impulses meet the sluggiih southward-moving coastal cur- rent, places where right whales lined up along the rips where plankton con- centrate. On a windless day in early April 1986, we decided to see ifright whales hadfoundsuch an area. The winter season, when right whales come to Cape Cod, had been a hard one, and calm hys like this were few, so we could at last get to the more distant convergence and, as localjshermen do, see what we could catch. It was gloomy and nearly dzrk when we lefi the port. For those of us who study whales, expectations are usually tempered by realip; we were lookingfor one of the rarest of all mammals in the shroud of the ocean. To- day, however, spirits were high as the hybreak was filed with springtime promise. Along the great outer beach of the Cape, so close to shore that we couldsmell the land nearb, thefist right whale was spotted working along one of those current rips. And as the sun climbed out of the haze, the whale rose and opened that great and odd mouth and skimmed the su$ace in a silence broken only ly the sizzle of water passing through its huge filtering Enormous Carnivores, Microscopic Food 139 apparatus. Our earlier optimism was warranted, andfor several hours we drzFedjust clear of the linear rip that the whale was working, recording the complex pattern of its movements. -

Nipigon Bay Area of Concern Status of Beneficial Use Impairments September 2010
Nipigon Bay Area of Concern Status of Beneficial Use Impairments September 2010 Nipigon Bay is in the most northerly area of Lake Superior. The Area of Concern takes in a large portion of Nipigon Bay and the Nipigon River, the largest tributary to Lake Superior, and the communities of Red Rock and Nipigon. There are Ontario Power Generation dams on the Nipigon River for the generation of hydroelectricity. The area supports a variety of wetlands and bird populations, including one of four known pelican colonies in Ontario. The watershed forests on both sides of the Nipigon River have been allocated for forest harvesting. Environmental concerns in the Nipigon Bay Area of Concern are related to water level and flow fluctuations in Lake Nipigon and the Nipigon River from the generation of hydroelectricity. These fluctuations affect stream bank stability, sediment load and fish and wildlife habitat. Other concerns include the accumulation of wood fibre, bark and other organic material from past log drives, and effluent discharges from a linerboard mill (which closed in 2006) and the municipal sewage treatment plants in Nipigon and Red Rock. PARTNERSHIPS IN ENVIRONMENTAL PROTECTION Nipigon Bay was designated an Area of Concern in 1987 under the Canada–United States Great Lakes Water Quality Agreement. Areas of Concern are sites on the Great Lakes system where environmental quality is significantly degraded and beneficial uses are impaired. Currently, there are 9 such designated areas on the Canadian side of the Great Lakes, 25 in the United States, and 5 that are shared by both countries. In each Area of Concern, government, community and industry partners are undertaking a coordinated effort to restore environmental quality and beneficial uses through a remedial action plan. -
Fact Sheet with Links to Key Information Can Be Accessed Online Here
Now is the time of reckoning for the decaying Enbridge Line 5 oil pipelines in the Straits of Mackinac and a proposed oil tunnel to replace them. On June 27, Michigan Attorney General Dana Nessel took decisive legal action on Line 5 in the Straits of Mackinac when she filed suit in Ingham County Circuit Court to revoke the 1953 easement that conditionally authorized Enbridge to pump oil through twin pipelines. Nessel’s lawsuit alleges that Enbridge’s continued operation of the Straits Pipelines violates the Public Trust Doctrine, is a common law public nuisance, and violates the Michigan Environmental Protection Act based on potential pollution, impairment, and destruction of water and other natural resources. Simultaneously, Governor Gretchen Whitmer and the natural resources and environmental protection agencies are defending the public’s rights and waters of the Great Lakes in Enbridge’s separate lawsuit against the state to build a tunnel under the Great Lakes for its oil pipelines to operate another 99 years. Gov. Whitmer also ordered the Michigan Department of Natural Resources to review violations of the Line 5 easement. As the state’s top leader and public trustee, the governor has the express legal authority to revoke the easement to start decommissioning the pipeline and to protect the Great Lakes. On June 6, Canada’s Line 5-owner Enbridge sued the State of Michigan to resuscitate a ‘Line 5’ oil tunnel deal and law rushed through in late 2018 at the end of the Snyder administration. Attorney General Dana Nessel in late March declared the oil tunnel law unconstitutional, triggering Gov. -

Misery Bay Chapter 2
Existing Conditions The first step in developing a plan to protect the coastal resources of Misery Bay is to establish an accurate representation of existing cultural and environmental features within the study area. This chapter will present a series of maps and associated text to describe key features such as owner type, land uses, vegetation cover types, soils and geology. NEMCOG used information and digital data sets from the Center for Geographic Information, State of Michigan, Michigan Resource Information System, Alpena Township, Alpena County, Natural Resource Conservation Service, and U.S. Geological Survey. Information from the Alpena County Master Plan and Alpena Township Master Plan was used to develop a profile of existing conditions. Field surveys were conducted during 2003. Community Demographics Trends in population and housing characteristics can provide an understanding of growth pressures in a community. Population trends from 1900 and 2000 are summarized in Table 2.1. Population levels have risen and fallen twice in the last 100 years, first in the early part of the century and again in the 1980’s. The 1980 US Census recorded the largest population for Alpena Township and Alpena County at 10,152 and 32,315 respectively. During the 80’s decade, population fell by over five percent and has not climbed back to the 1980 US Census level.
