Abstract
These shapefiles of lakes, streams, wetlands, river bottoms, and the Mississippi River represent the hydrological landscape of Minneapolis and St. Paul as recorded in the original public land survey conducted between 1848 and 1858. The hydrologic features were digitized from scanned, georeferenced 1:24000 maps during the 2017 Faculty Research Sprint held at the University of Minnesota.
Purpose
Many streams and other hydrologic features that were present in the Twin Cities at the time of the original land survey were channelized, covered, or filled during the late 1800's. These features, however, still function as water conduits within the hydrology systems of urban water and have immense importance to the water regime in the Twin Cities. This data was generated as part of a larger "Lost Waters" research project - aiming to create a visible, physical representation of these waters in the current urban landscape.

Data Quality Information
Logical Consistency Report
No integrity tests were conducted
Completeness Report
Hydrologic features which appeared on the land survey maps within the temporal and spatial extent of the study were digitized. The boundaries of hydrologic features vary with climate patterns and thus the snapshot of the landscape provided by the survey may have excluded some historic hydrologic features.

Entity and Attribute Overview
OBJECTID = an ID field automatically generated by the editing tool Date = an approximate date for the map from which the hydrologic feature was digitized Name = the name of the hydrologic feature, if recorded on the map MapName = the name for the map series ModernName = the current name (as of 2017) for the hydrologic feature, if known Shape_Leng = a field automatically generated for each object within the geodatabase (meters, calculated based on EPSG:4269) Shape_Area = a calculation of the polygon's area automatically generated for each object within the geodatabase (meters, calculated based on EPSG:4269)
