Title: Lake Michigan Bluff Crest Recession, Wisconsin 1956 - 2015
Contributors:- Point data
- 2015
Summary: Lake Michigan coastal bluff recession information is provided for Kenosha, Racine, Milwaukee, and Ozaukee Counties (collectively called “southeastern Wisconsin”). Data shown represents the distance the bluff has receded, or moved landward, over two analysis periods: a long-term period from 1956 to 2015 and a short-term period from 1995 to 2015. Recession information is provided for the bluff crest defined as the location where the relatively flatter upland meets the steeper bluff face.The coastal recession information was produced as a part of ongoing studies at the University of Wisconsin-Madison Coastal Sustainability Laboratory. This data has been made public through collaborations of the University of Wisconsin-Madison, the Wisconsin Coastal Management Program, University of Wisconsin Sea Grant, and the Association of State Floodplain Managers. The data presented here should be considered preliminary and may not reflect current conditions along the coast.Each data point represents an average of recession measurements along a 300-foot section of coast and does not represent any specific property or municipal boundaries. Note that a positive recession value represents a landward movement of the feature and a negative recession value represents a lakeward movement of the feature, also known as accretion.The recession information can provide useful insights into the historic migration of the southeastern Wisconsin coast. It should be noted that the recession distances provided here represent how the bluffs have responded to historic environmental conditions and human actions over a specific time period in the past (1956-2015 and 1995-2015). There is always uncertainty in how bluff recession will respond to future conditions. Bluff recession can also be sporadic. For example, a bluff crest that had remained unchanged for decades can recede many feet almost instantly due to a bluff collapse. Human actions may also change the evolution of the coast. For example, a bluff that may have been heavily eroded historically may have been recently stabilized or had shore protection added such that recession could be expected to decrease compared to historic rates.

Title: Lake Michigan Shoreline Recession, WI 1956-2015
Contributors:- Point data

Summary: Lake Michigan coastal shoreline recession information is provided for Kenosha, Racine, Milwaukee, and Ozaukee Counties (collectively called “southeastern Wisconsin”). Data shown represents the distance the shoreline has receded, or moved landward, over two analysis periods: a long-term period from 1956 to 2015 and a short-term period from 1995 to 2015. Recession information is provided for the shoreline defined as the location where the beach meets the water.The coastal recession information was produced as a part of ongoing studies at the University of Wisconsin-Madison Coastal Sustainability Laboratory. This data has been made public through collaborations of the University of Wisconsin-Madison, the Wisconsin Coastal Management Program, University of Wisconsin Sea Grant, and the Association of State Floodplain Managers.

It should be noted that the recession distances provided here represent how the shorelines have responded to historic environmental conditions and human actions over a specific time period in the past (1956-2015 and 1995-2015).

Title: Shoreline Structure, Wisconsin 2007
Contributors:- Point data
- 2007
Summary: These inventories are from the research of David Mickelson, Senior Scientist and Emeritus Professor at the University of Wisconsin.The Shoreline Inventory in the Great Lakes Coastal Oblique Photo Viewer are part of Dave Mickelson's research. The shoreline features in this file represent qaulitative 1976 backshore (bluff or low bank) conditions on Lake Michigan from Sturgeon Bay Canal south to the Illinois state line. Beach condition classifications used in the mapping were tested and modified several times before final mapping was begun.Initial results were reported to the Wisconsin Coastal Management's Coastal Hazards Committee, and their feedback and the initial testing led to the following beach and bluff classifications. All of the shoreline for each date (1976 and 2007) had three components of classification: beach description, backshore description, and structure type.Shore parallel structures that are onshore were mapped under beach description because they had length along the shoreline being segmented. Groins, jetties, and offshore breakwaters were mapped under structure type as points because most had no significant longshore dimension, or in the case of offshore breakwaters, no line to map on. Some were mapped as points and also as having extent along the shore.In 1976 black-and-white oblique air photos were taken by Wisconsin DNR as part of a major shoreline erosion project. They covered the Lake Michigan shoreline from Sturgeon Bay Canal south to the Illinois state line. They also covered the Wisconsin part of Lake Superior shoreline.In spring 2007 oblique digital photos were taken along the Lake Michigan shoreline from Sturgeon Bay Canal to the Illinois state line. Conditions along the shoreline were mapped in a GIS by David Mickelson between September, 2008 and February, 2009 using the 1976 and 2007 photos.The 1976 photographs were geo-located by identifying features that could be seen in the oblique views and Microsoft Virtual Earth and if necessary the 2007 oblique photos. The 2007 photographs were geolocated using software called GPS -- Photo Link (Geospatial Experts).
