Resource Abstract:
Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established
to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources
management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed
surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that
spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies
are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI
GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters
and causes; and (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset
(NHD). Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale
data (frequently provided by state GIS layers).

purpose:
One of the key goals of the Hydrographic and Impairment Statistics (HIS) project is to quantify the amount of water resources
that exist within and adjacent to NPS units. Hydrographic statistics are also necessary in order to provide a baseline for
GPRA reporting of impaired waters within NPS units. The Hydrographic and Impairment Statistics project is continuously being
updated with improved and more current data. Hydrographic statistics may change due to modifications to the park boundary
or to the NHD dataset. Impairment statistics are altered when new waters are 303(d) listed, TMDLs are developed, and/or when
impaired waters become delisted. Therefore, HIS strives to maintain accurate and reliable information to encourage better
management practices and decision-making.
