The drainage areas are nested within each other so that a large drainage area, such as the Upper Mississippi River, will be composed of multiple smaller drainage areas, such as the Wisconsin River. Previous Calwater versions (1.2 and 2.2) described California watersheds, beginning with the division of the State's 101 million acres into ten Hydrologic Regions (HR). The smaller sized 6th level sub-watersheds (up to 40,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. Inner gorges are geomorphic features consisting of steep slopes adjacent to channels. This zip file contains the files necessary to open CalWater 2.2.1 in ArcGIS to help populate specific fields in the Station Template. Bay Area Open Space Council, Conservation Lands Network, San Francisco Bay Area Upland Habitat Goals Project, and GreenInfo Network (Firm). An ArcGIS overlay map mervice for visualizing hydrographic. The California Landscape Conservation Cooperative (CA LCC) is a management-science partnership created to inform and promote integrated science, natural resource management and conservation to address impacts of climate change and other stressors within and across ecosystems. This document describes the rules that our editors of California's portion of the NHD should... Major Rivers and Creeks in California selected from the NHD in a zipped shapefile format.... Major Rivers in California selected from the NHD in a zipped shapefile format. NHD Data LayersSWAMP is requiring expanded National Hydrography Data Reach information. Provides direct download links and web-based map service information for The National Map. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. Both shapefiles are in the Albers Equal Area (NAD 83) projection – also referred to as the NAD 1983 California … These include the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), and NHDPlus High Resolution (NHDPlus HR). The Watershed Boundary Dataset (WBD) from The National Map (TNM) defines the perimeter of drainage areas formed by the terrain and other landscape characteristics. "The USGS manages surface water and hydrologic unit mapping for the Nation as geospatial datasets. California Watershed Network (CWN) - A non-profit organization formed in 2000, with the mission to help people protect and restore the natural environments of California’s watersheds while ensuring healthy and sustainable communities. The data is available for download as a shapefile, spreadsheet, or KML. Hbasa2 is a statewide version of the Teale GIS Technology Center (Teale) County Library data layer for hydrologic basins, called hbasa. California Hydrography datasets fulfill California's need of hydrography for visualization and mapping, as well as a common spatial base for in depth analysis of multiple data sets. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. Data Map Services. To insure data integrity, MPSL-MLML prefers this information be populated by the agency that has created the station. Monitor, manage, and report water quality The USGS National Hydrography Dataset (NHD) Downloadable Data Collection from The National Map (TNM) is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of surface water (lakes, ponds, and reservoirs), paths through which water flows (canals, ditches, streams, and rivers), and related entities such as point features (springs, wells, stream gages, and dams). Both shapefiles are in the Albers Equal Area (NAD 83) projection – also referred to as the NAD 1983 California … Stay Connected. CalWater also cross-references watershed codes implemented by the California Department of Water Resources (DWR), the California State Water Resources Control Board (SWRCB), and Regional Water Quality Control Boards (RWQCB), as well as Hydrologic Unit Codes (HUC) published by the U.S. Geological Survey (USGS) for California and the nation. At a minimum, SWAMP would like the 24k fields populated; however preferably, attributes from all three layers will be populated (NHD 24k, NHD 100k, and NHD Plus). An Excel file is also available to help populate specific fields if the corresponding CalWater information is known. California Department of Conservation administers a variety of programs vital to California's public safety, environment and economy. Map services for the spatial data provided by many of the map applications listed above are open and available for public developer use via our GIS server endpoint. Assess coastal hazards Model and map flood risk Since then, the California Department of Conservation, California Geological Survey (CGS) has been contracted by the California Department of Forestry and Fire Protection (CDF) to produce maps for parts of Mendocino, Humboldt, and Del Norte counties, and other selected watersheds throughout the state (see Watersheds Index Map). This dataset is the product of the Department of Conservation, California Geological Survey’s (CGS) investigation of landslides in the Elk River watershed. This line shapefile depicts inner gorges within the Elk River watershed in Humboldt County, California. We are working to provide a Station Locator tool to assist in populating this information. Hydrography data are integral to a myriad of mission critical activities undertaken and managed by government entities (Federal, state, regional, county, local, Tribal), nonprofit organizations, and private companies. If these resources are not available, contact your MPSL-MLML Liaison. Aerial Information Systems, Inc, Nature Conservancy (U.S.) , Danny Karp, and Sasha Gennet. As of this writing, there is no regular schedule for updates by HU8. Updates are made at the subbasin level (8-digit Hydrologic Unit Code, or HU8) and the updated dataset is posted within two weeks. info@mlml.calstate.edu A HU defines the areal extent of surface water drainage to an outlet point on a dendritic stream network or to multiple outlet points where the stream network is not dendritic. Discover, analyze and download data from California State Geoportal. Zip files containing GIS shapefile layers are available for use in software such as ArcGIS to help populate fields in the Station Template that are associated with CalWater, Counties, Ecoregion, HBASA, and NHD. Manage riverine and coastal navigation and safety Main: (831) 771-4400 Current geography in the 2016 TIGER/Line Shapefiles generally reflects the boundaries of governmental units in effect as of January 1, 2016, and other legal and statistical area boundaries that have been adjusted and/or corrected since the 2010 Census. OBJECTID: OBJECTID: NUMBER: 38: OBJECTID is a required attribute of feature classes … This zip file contains the shapefiles for the EPA Ecoregion Level 3 classifications based on Omernik (1987). Manage fisheries, rangeland, timberlands, and agricultural lands This data set is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The dephuc14 is NJDEP's version of the U.S. Geological Survey (USGS) hydrologic-unit-code basins that delineates the extent of the DEP watershed management regions and areas to be used for the statewide watershed initiative. This shapefile was downloaded from the California Forestry and Fire Protection website and used to represent the watersheds of California. This is a process that takes time with a State as large and diverse as California. DWR is the steward for NHD and Watershed Boundary Dataset (WBD) in California. Assess water availability and water rights An ArcGIS Tiled Base Map Service for visualizing hydrographic features. There a various ways to access the NHD data products. Territory in either file Geodatabase or Shapefile (PDF) format. The NHD Plus file was derived from http://www.horizon-systems.com/nhdplus/. The California Interagency Watershed Map of 1999 (Calwater 2.2, updated May 2004, "calw221") is the State of California's working definition of watershed boundaries. Stations sampled for bioassessment that fall within each boundary can have the corresponding IBI calculated. Provide recreational opportunities for citizens", DWR manages California's water resources, systems, and infrastructure, including the State Water Project (SWP), in a responsible, sustainable way. We work with other organizations to edit and improve NHD and WBD, using the business rules for California.
