Texas Streams

This dataset has been adapted for use as a cartographic and planning layer. The dataset has been simplified to a set of stream types that can be easily filtered using STRM_TYPE or the DISPLAY and DISPLAY_ALT fields. All geometric alignments are derived from the NHD dataset. Stream Type Domains 1 - Major River 2 - Flowing Stream 3 - Intermittent Stream 4 - Bayou 5 - Ditch 6 - Canal 7 - River 8 - Coastline 9 - Other (Includes underground pipelines) Filters and Queries Data can be filtered based on need either by the STRM_TYPE column or through two display columns. DISPLAY allows the user to granularly filter by major and flowing water sources and/or intermittent water features. DISPLAY = 1 will return all flowing water features. DISPLAY = 0 will return all intermittent features. DISPLAY is not null will return all cartographic water features. DISPLAY_ALT allows the user to filter for large scale and small scale views of the data. DISPLAY_ALT = 1 will return all major water features and flowing streams, canals, and bayous and should be used for small scale maps. DISPLAY_ALT = 0 will return intermittent streams and minor canals. DISPLAY_ALT is not null will return all cartographic water features and should be used for large scale maps.
