The Eugene water bodies layer, like its complement Eugene creeks, represents the destination for significant amounts of stormwater runoff in the Eugene area. This digital layer is closely integrated with the stormwater pipe layer, with numerous pipes terminating into these lakes and ponds as well as being the terminus for larger stream channels (Willamette River, Amazon Creek, the Millrace). This data is used frequently on GIS thematic maps of all types for reference to show the natural context of waterways. The accurate representation of Eugene lakes and ponds is critical for stormwater modelling and analysis, as well as for creating accurate usable field maps for Public Works Engineering and Maintenance. There are few limitations on the use of this data with the understanding that the lakes and ponds derive from multiple sources. Like any complex, interconnected digital data improvements in accuracy will occur over time as field supervisors note corrections in writing and feed that information back to GIS personnel. Some lakes have been named, many others have not. The representation of non-lakes on this layer, such as the Willamette river, Amazon Creek and larger downstream channels, allows large scale plots to show these waterways at appropriately. Several islands in these larger waterways contain the name 'out' so a reselect to exclude those would be appropriate for mapping. Annotation levels need to be refined for different scale plots. |
