Title: DNR Hydrography - Stream Routes with Stream Types

Abstract: Linear features representing statewide hydrographic features coded by stream type (e.g., perennial or intermittent stream, perennial or intermittent ditch, lake or wetland connector, etc.) See Attributes for a complete list of stream types.

Maintenance: Stream type segments are maintained as tabular data and displayed as linear events on the Stream Routes with Kittle Numbers and Mile Measures layer.
In the attribute table, designated segments extend from the FROM_MEAS (mile) to the TO_MEAS (mile) and have a total length = [LENGTH_MI] on a route with total length = [ROUTE_MI].

NOTE: In early 2015, stream type codes were transferred from the original DNR 24K Streams/MNDOT Basemap layer (derived from USGS topographic maps, circa 1960's-80's) to the current watercourse features in the DNR Hydrography Dataset layer. The stream types of some features (i.e., lake and wetland connectors) were updated to better integrate with open-water polygons. Others were changed to reflect watercourse channelization (i.e., stream types changed to ditch types). Despite these changes, there has been no comprehensive update to the stream type codes to reflect current hydrographic conditions. This especially pertains to the "perennial" vs. "intermittent" attributes. Thus, the current accuracy of assigned stream types, as well as the accuracy and completeness of the watercourse linework in relation to current 'real-world' conditions, is unknown.

New efforts in 2015 focus on development of methodology to derive new hydrography (i.e., streams and open water polygons) from LiDAR data sources. The increased level of detail, accuracy and currentness of the LiDAR data will lead to hydrography layers which much better reflect the current hydrography of Minnesota.


Purpose: To provide a comprehensive, statewide hydrography layer which serves as the base GIS layer for all DNR business needs, including mapping, analysis, reporting, statuatory responsibilities, etc. Examples of uses are regional hydrographic modeling/analysis, basemapping, limnological studies, and linkage to Fisheries data.

Section 2: Data Quality

Attribute Accuracy:

Logical Consistency:

Completeness: Data exist statewide. Many features have been re-digitized to better match aerial photography; others may be poorly digitized or missing from this dataset.

Horizontal Positional Accuracy: Horizontal positional accuracy is based originally on the 24K MNDOT Basemap source data. Many linear features have been improved by various partners via on-screen digitizing using DOQs and FSA imagery.

Vertical Positional Accuracy: N/A

Lineage: Linear hydrographic features were originally derived from MNDOT Basemap 1:24,000 scale data. Considerable editing and attributing of DNR-managed streams has taken place since 2000; attributes have been enhanced to better support DNR business practices. This dataset contains a collection of "best available features" from multiple sources, and represent various scales and accuracies. Thus, feature accuracy is highly variable and may not accurately reflect real-world conditions.

Section 5: Attributes

Overview: Attributes have been enhanced to better support DNR business practices. The original STRM_TYPE codes (describing water feature type) have been retained from the older DNR 24K/MNDOT 24k dataset (which were originally derived from USGS topo quad maps, circa 1960-1980's). Stream types of some features
have been updated to better integrate with open-water polygons (e.g., lake and wetland connectors) and to reflect watercourse channelization (i.e., stream types changed to ditch types). There has been no comprehensive update to these codes to reflect current hydrographic conditions.
