failing retaining wall may still be quite stable. Structures that are typically taken out for the winter months like movable docks and stairways were not recorded. These observations were recorded on a paper map. Finally, a third person took geo-tagged photos of the entire shoreline for reference. These photos can be viewed just like normal photos, but they also contain XY coordinates and the angle at which they were taken. (They can be mapped using ArcGIS 10.1, or by using the ArcPhoto add- on for older versions). In order to take high quality photos, the boat typically stayed between 50 and 100 feet from shore, but sometimes had to go farther out to avoid shallow water. The paper atlases were then digitized into three GIS shapefiles; one for erosion condition and recession rate (Recession_Rate.shp), one for shoreline structures like retaining walls and riprap (Shoreline_Structures.shp), and one for discrete structures like staircases, permanent docks, and buildings (Point_Structures.shp). All of this information was used to create an inventory atlas of the pool which can be found in the appendix to this document. The atlas contains erosion severity, shoreline structures, discrete structures, and photos of the entire shoreline. To find information about structure condition see the shapefiles provided with this document. Symbol Wisconsin NRCS Direct Volume Method Recession Rate Classifications Lateral Recession Category Rate (ft/yr) Description Slight 0.01 - 0.05 Some bare bank but active erosion not readily apparent. Some rills but no vegetative overhang. No exposed tree roots. Moderate 0.06 - 0.2 Bank is predominantly bare with some rills and vegetative overhang. Some exposed tree roots but no slumps or slips. Severe 3 0.3 - 0.5 Bank is bare with rills and severe vegetative overhang. Many exposed tree roots and some fallen trees and slumps or slips. Some changes in cultural features such as fence corners missing and realignment of roads or trails. Channel cross section becomes U-shaped as opposed to V-shaped Very Severe 0.5+ Bank is bare with gullies and severe vegetative overhang. Many fallen trees, drains, and culverts eroding out and changes in cultural features as above. Massive slips and washouts common. Channel cross section is U-shaped and stream course may be meandering.
