NHD – Framework for SLIMS
The National Hydrography Dataset (NHD) is a USGS/EPA created set of digital spatial data that contains information about naturally occurring and constructed bodies of water, natural and artificial paths through which water flows, and related hydrographic entities.
Within the NHD, features are combined to form reaches, which provide the framework for linking (or geocoding) water-related data to the NHD surface water drainage network.

Junctions
How is the NHD different from DEP’s current stream files?
NHD is a group of national hydrography layers representing streams as they are.
NHD utilizes reaches, which are segments of surface water (water bodies or streams) with similar hydrologic characteristics. Each reach has a unique ReachCode.
Presently, the NHD does not have River Mile Index (RMI) functionality built in.
The NHD uses 8, 10 and 12 digit HUC (Hydrologic Unit Code) levels to represent Subbasins, Watersheds and Subwatersheds, respectively. These boundaries are not affected by political boundaries.
Hydrologic Unit Levels
Benefits of the NHD
Data models utilizing the NHD can be used with limited additional development.
We now have streams outside of Pennsylvania. The NHD is better at using the Geographic Names
Information System (GNIS) to properly name stream segments.
The NHD provides easier integration with our Federal partners and surrounding states.
The NHD eliminates competing stream layers.
Conflation – Moving existing data to the NHD
Due to the complexity of moving existing enterprise records, the task was contracted to Research Triangle Institute (RTI) International, a non-profit company.
RTI was picked because of their history with helping USGS/EPA create the NHD, and their support of reach indexing of EPA programs such as 303(d), 305(b), WQS.
The Future of the NHD: Stewardship
The NHD is designed to be continuously updated by data stewards to correct any errors, along with adding new features and updates.
USGS is looking for partners at the state level to be the stewards for their respective states.
Pennsylvania DEP is in the final stages of developing a Memorandum of Understanding (MOU) with USGS on being the NHD data steward for Pennsylvania.
SLIMS Applications
NHD Locator
Web-based GIS tool to link enterprise records from the Environment, Facility, Application, Compliance Tracking System (eFACTS) and the Sample Information System (SIS) with the NHD
Enables the data to reference the NHD without having to go through the conflation process
Determines reach code and measures, since stream code and RMI are obsolete
NHD Locator
Instream Comprehensive Evaluation (ICE)
The geometry and attribute input portion of SLIMS, to include stream assessments, lake assessments, TMDLs, existing use, designated use, fish surveys, and macroinvertebrate surveys
Station and stream geometry now reference the NHD, and are stored in an enterprise geodatabase
