Description:
Abstract:
Inventory of surface water gaging station data including 7-Q-10 low and monthly stream flow.
Purpose:
Inventory of surface water gaging station data used for water quality studies, waste load allocations, distribution studies, and advanced waste treatment assessments.
Supplemental_Information:
The gage data were retrieved from the Gage File database. If necessary state and county FIPS codes were filled in from other fields where possible. The resulting ASCII file was converted into an ARC/INFO National Albers projection coverage for the United States. The coverage was then overlaid with county coverages (conterminous U.S., Alaska, Hawaii) to assign accuracy codes based on the state-county FIPS codes.

For distribution with BASINS v1.0, the national coverage was split into a series of coverages that included the spatial extent of each of the nine US EPA regions, plus the hydrologic accounting units that crossed Region boundaries. The nine regional coverages therefore overlapped at Regional boundaries. The coverages were distributed in PC ARC/INFO coverage format.

For distribution with Basins v2.0, the PA ARC/INFO coverages were exported on a PC then imported in workstation ARC/INFO v7.0.4. Each Regional coverage was then projected to geographic decimal degrees, NAD83. The coverages were then converted to ESRI Shapefile format, using the ARCSHAPE command.

Reviews Applied to Data An accuracy code was assigned based on a comparison of state and county FIPS codes. A site with a code value of 1 is within the correct county. A value of 2 is outside the county but inside the state. A value of 3 or 9 indicates coordinates outside the state. A site with value of 4 was formerly assigned a value of 3 or 9 but was reassigned based on visual inspection to be on the border of the correct county. Due to the amount of data, points with an accuracy code of 2 were not visually checked.

The sites with accuracy codes of 3 or 9 outside the correct state were visually inspected to determine if they were on the border of the county within which they were associated. The facilities found to be on the border were

BASINS v2.0 reviews: projected coverages were checked for topology. The shapefile format features and attributes were visually inspected and compared with the BASINS v1.0 PC ARC/INFO coverages.

The gage data was obtained from the US EPA Gage File database.

Overview_Description:
Entity_and_Attribute_Overview:

The following stream flow data are listed for each gage, when available: stream flow in CFS, 7-Q-10 low flow, and mean flow for each month.

Each point is identified by the AGCY unique code. The state and county FIPS codes and county name from the Gage File database are also included. The LATDD and LONGDD values were used to place the gages on USGS topographic maps from which they were digitized.

The ACCURACY code indicates whether the LAT/LONG matched the state and county FIPS codes from the Gage File database: 1 = correct county and state 2 = correct county incorrect state 3 = incorrect state 4 = incorrect county, but gage is on border of correct county 9 = incorrect state
