USGS National Hydrography Dataset (NHD): Flowline is the fundamental flow network consisting predominantly of stream/river and artificial path vector features. It represents the spatial geometry and carries the attributes. Data selected from NHD Flowline feature class to contain only FType code 460, StreamRiver (Perennial, intermittent) for the state of California.

This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.

This data depicts aquatic aerial fire retardant avoidance areas delivered as part of the 2011 Nationwide Aerial Application of Fire Retardant on National Forest System Land Environmental Impact Statement, the 2023 Supplemental Environmental Impact Statement, and the 2024 Record of Decision.This data shows areas where the aerial application of fire retardant should be avoided in order to prevent the potential of impacts to aquatic features across National Forest lands. The data is based on the high resolution National Hydrographic Dataset (NHD) produced by USGS. Each National Forest has the opportunity annually to modify the default NHD water representation (300ft buffer around all perennial and intermittent water features) to more accurately represent aquatic aerial fire retardant avoidance areas.This data is to be used in planning and implementation phases of U.S. Forest Service fire activities to help prevent intrusions of aerial fire retardant in these aquatic areas throughout National Forest lands. Provided here is a regionally merged dataset. This data has been merged, dissolved, and erased of attributes contained in each original component dataset. For this purpose, specific attributes are not necessary, as any spatial areas depicted simply show areas where aerial fire retardant use is to be avoided as stated in U.S. Forest Service guidelines.

Aerial retardant avoidance area for hydrographic feature data are based on high resolution National Hydrographic Dataset (NHD) produced by USGS and available from the USFS. Forests and/or regions have had the opportunity to modify the default NHD water representation (300ft buffer from all water features) for their areas of interest to accurately represent aerial fire retardant avoidance areas as described in the 2011 Record of Decision for the Nationwide Aerial Application of Fire Retardant on National Forest System Land EIS. These changes have been integrated into this dataset depicting aerial fire retardant avoidance areas for hydrographic features. The following process was used to develop the hydrographic areas to be avoided by aerial fire retardant. Initially, all intermittent/ephemeral and perennial features were buffered by 300 feet by the Forest/Region units. Subsequently, Forest/Region units may have extended these buffers locally based on their requirements. There may be overlapping features that have been created during the buffering process, so one must dissolve features before calculating any area values. Data is symbolized by FCODE. Using the FCODE attribute, streams/rivers/waterbodies are categorized into perennial and intermittent/ephemeral types. Avoidance features (streams and rivers) with FCODES 46003 and 46007, as well as features (lakes and other waterbody) with FCODES 39001, 39005, 39006, 43614, 46601 are considered intermittent/ephemeral features. All other FCODES are considered to be perennial features. All underground and covered water features (e.g., pipelines) are excluded. When symbolizing this information, perennial features should be drawn on top of intermittent/ephemeral features to give the proper message. Data displays at scales larger than 1:1,250,000. Data uses a Web Mercator projection. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee. Metadata and Downloads

VHDCARTO is a simplified version of the local resolution Vermont Hydrography Dataset (VHD) that has been enriched with stream perenniality, e.g., 'intermittent 'vs. 'perennial ', as well as, Strahler stream order attribution for the single linear feature class only. The primary means of accessing this information cartographically is via the FCODE and STREAM_ORDER fields, respectively. See the Entity and Attribution Information section for details. NOTE! Perenniality data does not exist for stream reaches contained within, or intersected by, Essex or Caledonia counties, thus the FCODE '46000 'in these areas. The absence of Soil SUrvey GeOgraphic (SSURGO) database information in these areas precluded the computation of perenniality. These areas will be processed at some future date. For information on the FCODE symbol for attribution or analysis see the following document http://nhd.usgs.gov/NHDinGEO_FCodes_by_layer.pdf (NHDFlowline). A two dimensional feature class for lakes, ponds and larger streams is also included in VHDCARTO. Both layers are derived from the latest National Hydrography Dataset (NHD) data. The NHD is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. For information on the science behind computing perenniality attribution please refer to the following U.S. Geological Survey Scientific Investigative Report (SIR) # 2006-5217 - http://pubs.usgs.gov/sir/2006/5217/pdf/SIR2006-5217_report.pdf

Water may or may not be present outside of rain events and may or may not exhibit channelization typically associated with streams. Those features are considered to be 'Unclassified Flowlines'. Records from the reprojected NHDFlowline feature class where FCODE = 46000 were extracted out of this dataset. All records from the source NHDFlowlines where FCODE 46000 can be found in this 'Classified Flowline' dataset."
