COVERAGE DESCRIPTION:
 
This coverage is a user created layer of river waterbodies.  It is a 
subset of Reach File 3.  The river reaches are created by the user selecting 
appropriate river reaches from the reach file as necessary for their assessment 
cycle.
 
For the purpose of this coverage all but the items listed below where 
removed from the original reach file 3 data set.

The hydrography layer consists of flowing waters (rivers and streams), 
standing waters (lakes and ponds), and wetlands--both natural and manmade.  
Two separate feature types are represented: polygons (areas) and lines.
Polygon features have attribute codes that identify water bodies such as 
lakes, wide river segments, or swamps.  Line features have attribute codes 
that represent streams or shorelines.
 
The hydrography layer was assembled from data originally published by the
U.S. Geological Survey (USGS) in Digital Line Graph (DLG-3) format. 
DLG-3 data were generated by USGS from 1:100,000-scale maps by manual 
digitizing and raster scanning.  Approximately 3200 original USGS DLG files 
were processed by Teale to create the statewide hydrography data layer.
 
Edits to the original linework have been made during the data conversion by 
Teale from the original DLG-3 format to the ARC/INFO(tm) GIS format.  Such 
changes include line movements (due to the map edge-matching process), minor 
corrections of attribute coding, and the closing of open polygons.  Flow 
direction for streams (type line) has also been added.  Stream lines are 
flagged (where item FLOW = 1) to indicate whether or not the direction of
a given stream (line) has been defined and/or verified by Teale.
  
Hydrography of the entire state is stored in 33 separate ARC/INFO coverages 
or tiles, whose individual boundaries correspond to the USGS 1:250,000-scale 
quad series (see index coverage called hydroindexa and index diagram below).
Coverage names consist of two unique characters plus a suffix -JHYSA.  Most 
of the two-letter codes abbreviate a quad name, for example: RDJHYSA, for 
the Redding quad.  The tiles are also numbered from 1 to 33, northwest to 
southeast, and this numeric code is contained in the item HYSNUM.  A separate 
item, HSCKEY, contains a number unique to each arc within a tile.  HSCKEY and 
HYSNUM are combined to form a primary key item, TDCKEY, which uniquely 
identifies every hydrograhy arc record statewide.  
 
In 1992, the Teale hydrography data layer was sent upon request to the U.S. 
Environmental Protection Agency (US EPA) Office of Water for use as a basemap 
for the River Reach File version 3-alpha, also known as Reach File 3 or 
RF3-alpha.  RF3 is US EPA's national hydrographic addressing system which 
contains unique water feature identification codes, names, and update 
documentation.  RF3 was developed by Horizon Systems Corporation, under 
contract to the US EPA Office of Water.  RF3 as archived at Teale consists of 
a separate data table for each of the 33 Teale hydrography coverages,
designated by the filename extension .DS3 (for example: RDJHYSA.DS3).
 
Hydrographic feature records in Teale's arc attribute tables (AAT) may be 
related (linked or joined) with corresponding RF3 records in DS3 tables on 
the item TDCKEY, which is present in both tables.  Users are cautioned to
verify the integrity of AAT - DS3 relations, as instances of many DS3 records 
relating to one AAT record are known to occur.  Use of the relate item 
RF3RCHID in older versions of Teale AATs has been discontinued. 
 
Reach File data, documentation, and technical support are provided through
the USEPA Office of Water's STORET User Assistance Group at 800-424-9067.
STORET is the USEPA's national water quality information system.

UPDATES
 
1996
 
The California Department of Fish and Game (DFG) assembled the most current
RF3 tables from copies downloaded directly from US EPA's National Computer
Center (NCC) in September 1996.  These DS3 tables, organized by hydrologic
basins, were appended and Teale tile-based tables extracted from them.
A significant volume of water feature names/name codes and RF3
identifiers were input and corrected by DFG in cooperation with the
California Rivers Assessment (CARA) program at UC Davis.  All such updates
are flagged in the item UPDTSRC2 in each DS3 table.  See details in
DATA DICTIONARY below.
 
February 1997
 
DFG reported inconsistency in DLG MINOR1 coding in Amboy (100k quad name),
99% of arcs were coded as WASHES. Apparently locoalized in a single 100K 
quad.  Modification were made so the coding consistent with the adjactent
quads.  The changes were made to 2 coverages: NEJHYSA and KIJHYSA.

  NOTE: Items common to all LINE coverages: FNODE#,   
  TNODE#, LPOLY#, RPOLY#, LENGTH, JHYSA# and    
  JHYSA-ID are not described here; with one exception:
 
     Where JHYSA-ID is negative (-ID < 0), arc is an 
     artificial neat line (coverage or tile boundary).
 
    FLOW: If equal to 1, flow direction is defined; if equal  
          to 0, no direction is defined.
  
  TDCKEY: Concatenates HSCKEY + HYSNUM to form a primary key for
          all hydro features statewide; links hydrography features
          in .AAT to US EPA River Reach File (RF3) records in DS3.
 
     DCU: Item inserted by DFG into Teale AAT; was derived from DFG-refined
          Cataloging Unit (CU) boundaries for use with USGS 1:100K hydrography.
          Coverage in development "hucdfg1d" was used to resolve cases where more
          than one RF3RCHID related to a single Teale feature.  Unresolved
          CU boundaries still exist in vicinity of Central Valley and Delta.
          Expect minor changes to DCU as CU boundaries are refined and
          standardized.
 
  HSCKEY: Unique number for each hydrographic feature within a single 
          tile.  Ranges from 1 to over 20,000 in some tiles.  Item was 
          created for RF3 use. Concatenated with HYSNUM to create TDCKEY.    
  
  HYSNUM: Hydrography tile sequence number, ranges from 1 to 33.  
          Item was created for RF3 use. 
          Concatenated to HSCKEY to produce TDCKEY.
  
 
  MAJOR1-5: Major codes denote hydrography (code 50) as the major 
            feature category to which a line element belongs (as 
            opposed to property boundaries, roads, etc within DLGs).
 
  MINOR1-5: Minor codes assign up to five descriptive subcategories 
            to any single hydrography line element.

DATA QUALITY ASSESSMENT:
  
The following are subjective comments regarding this data.
  
The USGS DLG features of this layer are fairly complete.  The density of 
line work representing drainage networks appears to vary arbitrarily from
quad to quad, and there are discontinuities in lines depicting streams at
the edges of 100k quads.  The geographic feature accuracy is fair.
Contiguous features are not always matched across map sheet boundaries.  
The attribute completeness and accuracy of MAJOR/MINOR code pairs is good.
The US EPA River Reach File version 3-alpha (RF3-alpha) as archived at 
Teale is an alpha release (prototype).  As such, users are cautioned to 
verify drainage network connectivity and water feature names before 
undertaking extensive processing using RF3 data.
 
County lines (a separate Teale data layer) and hydrography lines are not 
reconciled with each other and discrepancies between the two will occur 
when a county boundary follows a water feature.

SUPPLEMENTARY INFORMATION (courtesy of Calif. Department of Fish and Game)
 
In 1993, US EPA changed the Reach File table DS2 to DS3 and changed the
MILE and related items from numeric type to character type.  No data content
changes were made.  DFG compiled over 150 US EPA National Computer Center
(NCC) CU-based DS3 tables into a set of 33 Teale tile-based tables in
October 1996.  DFG and cooperators have also made extensive corrections
and additions of primary names/name codes in the DS3 tables.  Forwarding
of these updates is expected in October 1996 to US EPA for inclusion in
RF3-final processing.
 
The DS3 item UPDTSRC1 concatenates HYSNUM and HSCKEY (in that order) for
those records that have a corresponding AAT record.  UPDTSRC1 contains the
value 9999 for DS3 records created by US EPA that have no corresponding
record in the hydrography layer.  UPDTSRC1 contains leading zeroes for
single-digit HYSNUM values.  The Teale primary key, TDCKEY, is similar to
UPDTSRC1 except that the concatenation order is HSCKEY + HYSNUM.

INDEX TO 1:100,000 DLG HYDROGRAPHY 
 
ARC/INFO coverage names are composed of the prefixes shown in the statewide
grid below (some are abbreviations of the USGS 1:250,000-scale quad map 
series names), plus the suffix JHYSA for the line and polygon data layers 
(for example, RDJHYSA, for the Redding quad).   
 
The item HYSNUM in the ARC/INFO feature attribute tables contains the 
indicated numeric values to reference the tile within which a given 
feature falls.
