HYD_WATERBODY_POLY: This dataset contains waterbody features from the US Geologic Survey (USGS) High Resolution National Hydrography Dataset (NHD). NHD waterbody features include polygons depicting Lake/Ponds, swamp/marsh, estuaries, etc. Additional attributes have been added from the Bureau of Land Management (BLM) hydrography event data. This data will be refreshed as-needed to reflect updates to the NHD and Bureau of Land Management (BLM) hydrography event data.
This publication format is intended to improve the usability of the High Resolution NHD and Bureau of Land Management (BLM) hydrography event data by combining attributes from both sources into one dataset with a simplified structure. The publication format includes the most commonly used attribute information. Other less commonly used attributes are available directly from the Bureau of Land Management (BLM) hydrography event data system.

Attributes were compared with the source material for accuracy. Discrepancies were cross checked with other sources to determine and confirm the correct attribute.
Source Data derived from the BLM addresses positional accuracy by referring to the error ellipses from the Geographic coordinate data base (GCDB). Other Source data derived from other Federal, State, and county sources as a rule did not address positional accuracy. Accuracy was then determined from metadata statements if available.
NHD data provides source for base geometry, route system, and feature attributes.

The Hydrography Publication production process begins with NHD data as the source for base geometry, route system, and feature attributes. Linear event tables are queried and prepared for event overlay. Species-specific fish are processed to bring most recent events forward where overlapping events occur. All the event tables are combined through the process of event overlay to bring all attributes in to one event table. The combined event table is coupled with the NHD route system to write out segments of stream geometry for each unique combination of attributes. Feature-level metadata information is derived/calculated from NHD metadata and source citation tables. Hydrographic category is derived from NHD Fcodes. One of the last steps of the publication process is to remove features, based on the reach code, from the Hydrography Publication Dataset that appear in the Hydrography delete feature classes (HYD_FLOWLINE_DEL, HYD_POINT_DEL, HYD_POLY_DEL). Then new or modified features in the add feature classes (HYD_FLOWLINE, HYD_POINT, HYD_POLY) are appended to the Hydro Publication Dataset. For individual subbasin files, a topology is then built to show overlapping segments.

HYD_FLOW
Flow
Captures the transition point of the temporal expression of stream flow. A stream reach may be: a) Perennial - Perennial streams generally have a well-defined channel that contains water continuously during a year of normal rainfall, often with the streambed located below the water table for most of the year. Groundwater supplies the baseflow for perennial streams, but flow is also supplemented by stormwater runoff and snowmelt. b) Intermittent - Intermittent streams contain water for only part of the year, typically during winter and spring when the streambed may be below the water table and/or when snowmelt from surrounding uplands provides sustained flow. Streamflow may vary greatly with stormwater runoff. c) Ephemeral - Ephemeral streams flow only in direct response to large precipitation events or stormwater runoff. An ephemeral stream may or may not have a well-defined channel, the stream bed is always above the water table, and stormwater runoff is the primary source of water. While the periodicity of a stream is determined by the dominant or the most representative features within a reach, the distinction between perennial, intermittent, and ephemeral channels is often dependent on a wide range of temporal and spatial scales. Ephemeral and intermittent streams are common in the semiarid landscapes of eastern Oregon and have distinctly different characteristics from the perennial streams that are found in the wetter, more humid climate of western Oregon. While the stream flow definitions provided above give a broad understanding of these terms, relevant terminology within local Resource Management Plans should be consulted. Application of local management plans ensures that stream periodicity attribution is in alignment with land use allocations and overall management direction.
In the Oregon Forest Practices Act, a key distinction between perennial and intermittent streams is that the former is defined as a stream that normally has summer surface flow after July 15, whereas the latter is defined as a stream that normally does not have summer surface flow after July 15. Although the stream survey date in itself won’t affect a stream’s periodicity, it can influence the surveyor who may or may not be able to key in on the biologic and/or geomorphic stream flow indicators used to determine the flow status of streams, which are often inconspicuous and may not be well defined at all locations or may not be evident at all times.

BLM_ORG_CD
BLM Org Code
A combination of the BLM administrative state and field office that has administrative responsibility for the spatial entity. This includes which office covers the entity for planning purposes and which office is the lead for GIS edits. Another agency or individual may have the physical management responsibility for the on-the-ground entity. This field applies particularly when a spatial entity crosses resource area or district boundaries, and the administrative responsibility is assigned to one or the other rather than splitting the spatial unit. Similarly, OR/WA BLM may have administrative responsibility over some area that is physically located in Nevada, Idaho, and California and vice versa. When appropriate, the office can be identified only to the district or state level rather than to the resource area level.
This field is auto calculated on record creation. However, it can be changed to correct the value.
