0: unnetworked reach
1: reach in the main networked path that
connects catalog units or is the lowest
level path in headwater catalog units.
2: tributaries to reaches with NEW_RFTHIN =1
3: tributaries to reaches with NEW_RFTHIN =2.
4: tributaries to reaches with NEW_RFTHIN =3
5: tributaries to reaches with NEW_RFTHIN =4
6: tributaries to reaches with NEW_RFTHIN =5
7: tributaries to reaches with NEW_RFTHIN =6
"No" where Type:
A - Artificial Lake Reach
C - Coastal or Continental Shoreline Segment
G - Great Lakes Shoreline Segment
I - Island Shoreline Segment
M - Artificial Open Water Reach
V - Open Water Terminal Reach
* W - Wide-River Shoreline Segment
Y - International Boundary Reach
* Note: In some cases the display value was changed to yes because the wide river
shoreline extended further inland than NOAA s Coastal Assessment Framework
shoreline. COLUMBIA R, SUSQUEHANNA R, WILLAMETTE R only part of the river has
a "yes" code for display DETROIT R, SNAKE R -- entire river has "yes" code to be
displayed.
"Yes" where Type:
B - Bi-directional Reach (A reach for which the direction of flow is ambiguous.)
D - Dam Reach (A reach which is a dam through which and/or around which water flows.)
E - Entry Reach (A reach which receives flow from Canada or Mexico.)
F - Falls Reach (A reach which is either a waterfall, drop spillway or a reach of
rapids.)
L - Lake Shoreline Segment (A segment which follows the shoreline of a lake other than
one of the Great Lakes.)
N - Non-Connected Reach (A reach not having codes to link it to other reaches.)
R - Regular Reach (A reach which has upstream and downstream reaches connected to it and
which is not classified as another type of reach.)
S - Start Reach (A headwater reach which has no reaches above it and either one or two
transport reaches connected to its downstream end.)
T - Terminal Reach (A reach downstream of which there is no other reach (for example, a
reach which terminates into an ocean, a land-locked lake, or the ground).
X - Terminal Start Reach (A reach which is both a terminal reach and a start reach.)
Z - Terminal Entry Reach (A reach which is both a terminal reach and an entry reach.)
a - t: Identifies individual subEDAs found in estuaries where subEDAs have been
defined (e.g., Chesapeake Bay). Only EDAs have subEDAs.
w: Identifies those polygons in an EDA not already assigned to a subEDA. The
remaining core of the major EDACDA Watershed. Applies only to EDAs that have
subEDAs.
x: All other polygons. These include all major watersheds (EDAs) that do not have
SubEDAs.
N - Rivers of the North Atlantic region. M - Rivers of the Middle Atlantic region. S - Rivers of the South Atlantic region. G - Rivers of the Gulf of Mexico region. P - Rivers of the Pacific region. L - Rivers of the Great Lakes region. U - Rivers within the US border, but not a part of the CAF. X - Rivers outside US boundaries.
E: Coastal Component - Either an Estuarine Drainage Area (EDA), Coastal Drainage Area (CDA), or Great Lake / St Lawrence River CDA polygon. F: Upstream Component- Either an Fluvial Drainage Area (FDA), Fluvial Coastal Drainage Area (FCDA) or Great Lake / St Lawrence River CDA polygon. I: An Interior Watershed polygon (includes self-contained, groundwater drainage only, and those draining to areas other than the United States).
