How to Use WestDAAT Filters?

This page explains the usage and terminology behind each WestDAAT filter.  WestDAAT is currently separated into three different sections: (1) Reset All Filters, (2) Color and Size Tools, (3) Water Right Selection Filters, and (4) NLDI Filter. Note: This page has been reviewed and updated over time. 

Reset All Filters

The Reset All Filters button allows the user to reset all user-selected filters back to their starting default values.

Color and Size Tools

This section contains controls that allow a user to change how the data on the map is viewed.  There are currently three filter options: (1) change the map legend, (2) toggle POD point size and (3) background map layer imagery.

1. Change Map Color Legend The drop-down list changes the accompanying map legend, which displays the meaning of the colors and styles used to represent geographic data on the map.  Data relates to the following specific to water rights data: (1) beneficial use classification, (2) owner type classification, and (3) water source type classification. 2. Toggle Point Size Toggle button that changes the POD size on the accompanying map to the following: (1) Default, which makes all points the same & is the standard size; (2) Flow, which sizes POD points based on assigned allocated to the water right; (3) Volume, which sizes PODs points based on assigned allocated volume to the water right.
3. Toggle View The toggle button changes the view to include: (1) All POD and POU sites; (2) just POD sites; (3) just POU sites.
4. Map Layer Toggle button that changes the background imagery. Gives the user the option to view the data displayed on a different background map.

Water Right Selection Filters

This section contains controls that allow a user to filter down the available sites on the accompanying map based on the following criteria related to water right information: (1) state, (2) beneficial use classification, (3) water source type classification, (4) text search box for water right owner name, (5) owner type classification, (6) river basin selection demo, (7) water right POD or POU toggle, (8) WaDE mapping exempt status toggle, (9) priority date beginning and end date range entry, (10) water right assigned flow minimum and maximum range entry, and (11) water right assigned volume range minimum and maximum range entry.

1. State A drop-down list of states where available water rights data can be found.  States are presented in alphabetical order in abbreviated form.
2. Beneficial Use  A drop-down list of WaDE classified specific use(s) authorized under a water right expressed in terms of the purpose(s) to which the water may be applied. WaDE classified beneficial uses are for sorting and viewing purposes only for WestDAAT and have been approved by the WSWC member states.  They are an abridged list of common terminology from the vast array of recognized beneficial uses throughout the Western States.  See individual water right landing pages for provided native state terminology.
3. Water Source Type A drop-down list of WaDE classified water source types applied to water rights. Types mostly include water rights sites divided between surface water, groundwater, and unspecified (site sites that were not able to be classified). WaDE-classified water source types are for sorting and viewing purposes only for WestDAAT and have been approved by the WSWC member states.  They are an abridged list of common terminology from the vast array of recognized water source types throughout the Western States.
4. Search Allocation Owner A single-line text box that accepts the user’s input search strings to perform an exact search on Water right’s owner name information as recognized by the providing state organizations.
5. Owner Classification Type A drop-down list of WaDE classified owner types applied to water rights.  They are an abridged list of common terminology from the vast array of recognized owner types throughout the Western States. Assigned values are determined by utilizing a keyword search algorithm using the state-provided water right owner (e.g., Allocation Owner) information. The keyword search starts with a generic term search but then is overridden with a more term-specific search. Water right records can possess multiple owners and records within WaDE with multiple Allocation Owner entries were given the first term available. Terms not found in the keyword search were given the default value of “In Review”, for further review by the WSWC staff and state agencies. For more information on how owner types are determined, see here.
6. River Basin Areas A drop-down list of river basins is used to select water right locations within a specific river basin area.  Provided list is for demonstration purposes only using those areas that received the most requests during the development of WestDAAT.  Plans on either expanding the available list to include additional river basins or plans on expanding the tool itself to encompass a larger variety of area types are in development and will be made available sometime in the future.
7. Availability of Priority Data and Amounts Toggle button that displays water rights sites & records determined to be exempt from WaDE’s data mapping regulations and rules. Sites and records include those missing information that is key to the WaDE 2.0 system architecture but considered excused as missing information will not be readily available for some time.  Missing key information can include one of the following: (1) the lack of provided flow or volume allocation records per water right recognized by the state, or (2) a recognized priority date not provided or ever recorded for the water right.
8. Priority Date Date range input control that allows a user to select dates that would encompass a water right date record. Can define a custom date range by choosing start and end dates.  Values are given in MM/DD/YYYY format.
9. Flow Range (CFS) Flow range input control allows a user to select flow values that would encompass a water right date record. Can define a custom flow range by entering in a minimum, maximum, or both flow value(s).  Appropriate values range from 0 and up.
10. Volume Range (AF) Volume range input control that allows a user to select volume values that would encompass a water right date record. Can define a custom volume range by entering in a minimum, maximum, or both volume value(s).  Appropriate values range from 0 and up. Might be worth adding a list of all options in each drop-down CV filter either here listed in a table, or a link to a posted page on a WSWC / WaDE documentation page that talks about the CV terminology project(s).

NLDI Filter

This section contains controls that allow a user to utilize the Hydro Network-Linked Index (NLDI) and Geoconnex Framework tool.  This tool is a system that can index spatial and river network-linked data and navigate the river network to allow the discovery of indexed information. NLDI puts a restful application programming interface (API) in front of the National Hydrography dataset.  For further information, see here: https://waterdata.usgs.gov/blog/nldi-intro/ This tool has the following applications for WaDE: (1) drag and drop pin tool, (2) text entry box for latitude values, (3) text entry box for longitude values, (4) toggle button to indicate the direction of the query of site data, (5) toggle button to receive site information for other federal agencies as part of the Geoconnex Framework.

1. NLDI Filter A toggle button to initiate the NLDI tool.  This will expand the NLDI filter tool to its full extent and clear the map of all currently viewed sites water right sites for ease of site / pin location selection.  Relevant sites to the NLDI tool call will regenerate to the selected pin location.
2. Drag and Drop Pin Tool A drag-and-drop pin that allows a user to generate NLDI results wherever they want on the accompanying map. After doing so, the latitude and longitude text box entries are auto-filled.  Uses EPSG: 4326 geographic coordinate system.
3. Latitude The optional text entry field for latitude values for the NLDI query.  Auto-filled with the above Drag and Drop Pin tool. Uses EPSG: 4326 geographic coordinate system.
4. Longitude The optional text entry field for longitude values for the NLDI query.  Auto-filled with the above Drag and Drop Pin tool. Uses EPSG: 4326 geographic coordinate system.
5. Direction Toggle button(s) that indicate the direction of the river index query.  Can be toggled on or off.
6. Scope of Query Toggle button(s) to indicate the scope of site data to query and return. Can be toggled on or off. Includes options from other Geoconnex Framework partners. Options at this time include (1) WaDE water right sites, (2) USGS stream gage sites, and (3) EPA water quality sites.
