These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online
mapping viewer depicting potential water level increase and decrease in the coastal areas of the Great Lakes. The lakes included are: Erie, Huron, Michigan,
Ontario, St. Clair, and Superior. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at lake level
change and potential coastal impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses to help users examine
multiple scenarios and prioritize actions. The Lake Level Viewer may be accessed at https://coast.noaa.gov/llv.
These data consist of 13 water extent polygons and 13 water depth rasters (3 m resolution, depth values in meters) that show the potential water level when
the water level is decreased from 0 feet to -6 feet (resulting in potential land exposure) and when water level is increased from 0 to +6 feet (resulting
in potential flooding). These data are based on the each lake's long term average water level over the period of record (1913-2008). More information on
the long term average water level can be found at https://www.glerl.noaa.gov//pubs/fulltext/2013/20130021.pdf,
https://www.glerl.noaa.gov//pubs/fulltext/2013/20130022.pdf, and the Great Lakes Water Level Dashboard (https://www.glerl.noaa.gov/data/dashboard/GLWLD.html).
The process used to produce the data can be described as a bathtub approach. The process uses two source data sets to derive the final water extent polygons
and water depth rasters for each iteration of water level decrease or increase: the Digital Elevation Model (DEM) of the area and each lake's long term
average water level over the period of record (1918-2017) at the time of data set creation. Data can be downloaded at https://coast.noaa.gov/llv.
The model used to produce these data does not account for erosion, subsidence, or any future construction. Water levels are as they would appear during calm
conditions (excludes wind-driven effects). As with all remotely sensed data, all features should be verified with a site visit. The data are provided as is,
without warranty to their performance, merchantable state, or fitness for any particular purpose. The entire risk associated with the results and
performance of these data is assumed by the user. This data should be used strictly as a planning reference and not for navigation, permitting, or other
legal purposes.
The purpose of these data is to provide the user with information that can help communicate potential lake level change impacts as a result of either
water level decrease or increase. These data can be incorporated with the user's own data in order to make customized lake level impacts analyses.
Acknowledgment of the NOAA Office for Coastal Management (OCM) as the data source would be appreciated in products developed from these data, and
such acknowledgment as is standard for citation and legal practices for data source is expected.

dataset
Completeness Report
These data are complete. Data supplied are from the most current elevation data available at the time of creation. Gaps may exist, but these are due
to a lack of available elevation data at the time of data set creation.
Conceptual Consistency
Standard methods for determining water level decrease and increase were used. The vertical accuracy of these data is dependent on the source elevation
data.
The process to derive the rasters and polygons is as follows:
1. A water level surface is generated for each lake using each lake's long term average water level over the period of record (1918-2003). Each 1 foot
iteration (from -6 feet to + 6 feet) of water level was either subtracted or added to this base water level surface and subsequently used for mapping.
2. Using the DEM and the water level surface (for each 1 foot iteration of drop or rise), raster calculations are made using ArcGIS Spatial Analyst
Raster Calculation tool to generate multiple rasters, one 32-bit floating point raster representing the depth of water level and one 8-bit single value
raster representing the extent of water level.
