This web map contains datasets representing the National Hydrography Dataset (NHD) of Washington State, labels for NHD features, and the Watershed Boundary Dataset (WBD) basins for Hydrologic Unit Code (HUC) levels 4, 8, and 12. The NHD dataset has been adopted as the Washington State hydrography standard. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.This high-resolution NHD, generally developed at 1:24,000/1:4,800 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. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.This map contains a BETA version of WaterType attached to the Skagit River Basin NHDflowlines. This Beta version of the Watertype is the result of a pilot project and will be refined over the next six months. The field is for users of NHD who want access to Water Type and who are not under Forest Practices rules. The WaterType uses Shorelines Master Program type S streams and Fish Presence Data from both WA Dept Natural Resources and WA Dept Fish and Wildlife.

A revised State Planning Policy 2.3 – Jandakot Groundwater Protection (SPP 2.3) was gazetted on 11 January 2017. SPP 2.3 aims to protect the Jandakot Groundwater Protection Area from development and land uses that may have a detrimental impact on the water resource. The objectives of this policy are: To ensure that all development and changes to land use within the policy area are compatible with maximising the long-term protection and management of groundwater, in particular for public drinking water supply; To protect groundwater quality and quantity in the policy area in order to maintain the ecological integrity of important wetlands that are hydraulically connected to that groundwater, including wetlands outside the policy area; To prevent, minimise or manage development and land uses that may result in contamination of groundwater; and To maintain or increase natural vegetation cover over the policy area. The policy provides guidance regarding planning requirements that need to be considered in the policy area and should be read in conjunction with the Department of Water’s Water quality protection note 25: Land use compatibility tables in public drinking water source areas (as may be amended from time to time). All proposed development within the Jandakot Groundwater Protection Area should be consistent with Tables 1, 2 and 3 which set out appropriate land uses and activities within the assigned priority area. Priority areas may change from time to time. The relevant priority areas and wellhead protection zones within the Jandakot Groundwater Protection area can be found on the Department of Planning’s PlanWA interactive planning map. For any enquiries regarding the policy, contact waterpolicies@planning.wa.gov.au.

These polygon features represent Water Quality Improvement (WQI) projects managed by the Washington State Department of Ecology. WQI projects can be TMDLs, Straight To Implementation (STI) plans, 4b projects and TMDL Alternatives. The boundaries show where the WQI project applies and is being implemented. TMDL Boundaries identified as "In Development" are considered draft and are subject to change when the project has been approved by the U.S. EPA. U.S. EPA only approves TMDLs and 4b projects. Boundaries are representations of each particular project and does not replace the official version of the approved TMDL report. Please see the TMDL Project webpage for specific information about that project. TMDL projects are required by the Federal Clean Water Act to identify pollution sources and pollution load reductions needed for water bodies to meet water quality standards. Once a TMDL project has been approved by the U.S. EPA, it enters an implementation phase where both point source and non-point source pollution is reduced through permit limits regulated under the NPDES system and through best management practices for land uses that contribute to non-point source pollution. Ecology’s water quality program works with permittees, local governments, watershed stakeholders, and residents to reduce sources of pollution to protect our aquatic resources and public health.

The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public open space and voluntarily provided, private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastral Theme (http://www.fgdc.gov/ngda-reports/NGDA_Datasets.html). PAD-US is an ongoing project with several published versions of a spatial database of areas dedicated to the preservation of biological diversity, and other natural, recreational or cultural uses, managed for these purposes through legal or other effective means. The geodatabase maps and describes public open space and other protected areas. Most areas are public lands owned in fee; however, long-term easements, leases, and agreements or administrative designations documented in agency management plans may be included. The PAD-US database strives to be a complete “best available” inventory of protected areas (lands and waters) including data provided by managing agencies and organizations. The dataset is built in collaboration with several partners and data providers (http://gapanalysis.usgs.gov/padus/stewards/). See Supplemental Information Section of this metadata record for more information on partnerships and links to major partner organizations. As this dataset is a compilation of many data sets; data completeness, accuracy, and scale may vary. Federal and state data are generally complete, while local government and private protected area coverage is about 50% complete, and depends on data management capacity in the state. For completeness estimates by state: http://www.protectedlands.net/partners. As the federal and state data are reasonably complete; focus is shifting to completing the inventory of local gov and voluntarily provided, private protected areas. The PAD-US geodatabase contains over twenty-five attributes and four feature classes to support data management, queries, web mapping services and analyses: Marine Protected Areas (MPA), Fee, Easements and Combined. The data contained in the MPA Feature class are provided directly by the National Oceanic and Atmospheric Administration (NOAA) Marine Protected Areas Center (MPA, http://marineprotectedareas.noaa.gov ) tracking the National Marine Protected Areas System. The Easements feature class contains data provided directly from the National Conservation Easement Database (NCED, http://conservationeasement.us ) The MPA and Easement feature classes contain some attributes unique to the sole source databases tracking them (e.g. Easement Holder Name from NCED, Protection Level from NOAA MPA Inventory). The "Combined" feature class integrates all fee, easement and MPA features as the best available national inventory of protected areas in the standard PAD-US framework. In addition to geographic boundaries, PAD-US describes the protection mechanism category (e.g. fee, easement, designation, other), owner and managing agency, designation type, unit name, area, public access and state name in a suite of standardized fields. An informative set of references (i.e. Aggregator Source, GIS Source, GIS Source Date) and "local" or source data fields provide a transparent link between standardized PAD-US fields and information from authoritative data sources. The areas in PAD-US are also assigned conservation measures that assess management intent to permanently protect biological diversity: the nationally relevant "GAP Status Code" and global "IUCN Category" standard. A wealth of attributes facilitates a wide variety of data analyses and creates a context for data to be used at local, regional, state, national and international scales. More information about specific updates and changes to this PAD-US version can be found in the Data Quality Information section of this metadata record as well as on the PAD-US website, http://gapanalysis.usgs.gov/padus/data/history/.) Due to the completeness and complexity of these data, it is highly recommended to review the Supplemental Information Section of the metadata record as well as the Data Use Constraints, to better understand data partnerships as well as see tips and ideas of appropriate uses of the data and how to parse out the data that you are looking for.

Critical Aquifer Recharge Areas means those land areas that contain hydrogeologic conditions that facilitate aquifer recharge and/or transmit contaminants to an underlying aquifer. Critical aquifer recharge areas under this title may be established based on general criteria, specifically designated due to special circumstances, or based on scientific studies and mapping efforts. Factors considered in the identification of critical aquifer recharge areas include depth to water table, presence of highly permeable soils (specifically Group A Hydrologic Soils), presence of flat terrain, and the presence of more permeable surficial geology. Category I critical aquifer recharge areas are those areas where the potential for certain land use activities to adversely affect groundwater is high. Category I critical aquifer recharge areas include: 1. Areas inside the five-year time of travel zone for Group A water system wells, calculated in accordance with the Washington State Well Head Protection Program. 2. Areas inside the ten-year time of travel zones in wellhead protection areas when the well draws its water from an aquifer that is at or above sea level and is overlain by permeable soils without an underlying protective impermeable layer. 3. Areas identified as Significant Recharge Areas due to special circumstances or identified in accordance with WAC 365-190-080 (2) (c) as aquifer areas of significant potable water supply with susceptibility to groundwater contamination, including but not limited to the following: a. Hansville Significant Recharge Area. The Hansville aquifer is a significant potable water supply that is highly susceptible to the introduction of pollutants. Additional information regarding this aquifer is available from the Kitsap Public Utility District. b. Seabeck Significant Recharge Area. The Seabeck aquifer is a significant potable water supply that is being developed for use in central and north Kitsap County. Additional information regarding this aquifer is available from the Kitsap Public Utility District. c. Island Lake Significant Recharge Area. The Island Lake aquifer is a significant potable water supply for the Silverdale area. Additional information regarding this aquifer is available from the Silverdale Water District. d. Gorst Significant Recharge Area. Aquifers in the Gorst basin are highly susceptible to the introduction of pollutants and provide significant potable water supplies for the City of Bremerton. e. Poulsbo Significant Recharge Area. The Poulsbo aquifer is highly susceptible to the introduction of pollutants and provides a significant potable water supply for the Kitsap Public Utility District and City of Poulsbo. 4. The department may add, reclassify or remove critical aquifer recharge areas based on additional information about areas of significant potable water supply with susceptibility to groundwater contamination or based on changes to sole source aquifers or wellhead protection areas as identified in wellhead protection programs

This is a view of the DischargePoint featureclass created with the following query: LifeCycleCurrentStatus= 'Active' AND (WSDOTownership in ('Yes', 'Unknown') OR WSDOTownership IS NULL) AND SWLocationVerified = 'Yes' This feature class contains WSDOT’s stormwater discharge points. A stormwater discharge point is the point at which WSDOT loses, or obtains, jurisdictional responsibility of concentrated stormwater from a constructed stormwater conveyance feature. This includes locations where stormwater infiltrates into the ground at the end of a constructed stormwater conveyance, or enters surface waters of the state through a constructed stormwater conveyance. The majority of the data collected so far are within the Phase I and Phase II 2009 NPDES Municipal Stormwater Permit Areas. Additional data were collected during stormwater retrofit review and mapping in Total Maximum Daily Load areas that are outside of the permit area. This feature class has five subtypes: Incoming, Land Surface, Managed System, Subsurface, and Surface Water.

Critical aquifer recharge areas are those areas that provide a critical recharging effect on aquifers used for drinking water, including areas that are vulnerable to contamination or reduced recharge.CARAs are divided into three categories depending on sensitivity: Category I - extreme aquifer sensitivity; Category II - high aquifer sensitivity; Category III - moderate aquifer sensitivity. See Thurston County Code Chapter 24.10.010 for full definitions.This data set combines soil-based CARAs with geology-based CARAs. Geology-based CARA categories were developed in conjunction with Nadine Romero, Thurston County's hydrogeologist, using available data from the Washington State Department of Natural Resources. Where an area has conflicting CARA categories between soils and geology, the more restrictive category prevails. Geology mapping at the 1:24,000 scale was only available for some portions of the county at the time of CAO update, the rest is mapped at 1:100,000 scale. Therefore it is important to not to accidentally use the data at a scale beyond its native resolution. The geology data are organized by quads. The 24k quads are: Shelton, Squaxin Island, Longbranch, Summit Lake, Tumwater, Lacey, Nisqually, Maytown, and East Olympia. The 100k quads are: Kamilche Valley, Capitol Peak, Little Rock, Tenalquot Prairie, McKenna, Harts Lake, Oakville, Rochester, Violet Prairie, Bucoda, Vail, Lake Lawrence, Bald Hills, Eatonville, and Elbe. This data was created by the Thurston County Hydrogeologist and Long Range Planning staff in 2014-2015 using USDA NRCS Soils data and Department of Natural Resources Geologic Data.
