second classifies flow in terms of seasonal behavior (duration).
HYDFLOW DESCRIPTION
------- ----------------------------------------------------------
Cx Continuous - a channel that does not have interruptions in
space
Ix Interrupted - a channel that contains;
A. perennial flow with intervening intermittent or ephemeral
segments
B. intermittent flow with intervening ephemeral segments
Gx Groundwater - reaches that represent subsurface flow
xP Perennial - streams that essentially flow year round
xS Intermittent or seasonal - flows certain times of year when
it receives water from springs, snow melt, etc.
xE Ephemeral - flows only in direct response to storm
precipitation and whose channel is at all times above the
water table
xU Unclassified
For example, CP describes a Continuous channel with Perennial flow.

canals, and pipelines.

This field is a concatenation of 3 data components, the first 2
separated by a "pipe" character (|) and the last 2 separated
by a colon character (:). The first data component is a feature
type derived from the DLG or CFF data (refer to the BLM handbook
for more explanation). The 2nd and 3rd data components use the
same codes to define the source of HYDFLOW and PLANFLOW enties,
respectively. The codes and descriptions are provided below.
FS attributed from Forest Service data
MP mass populated with a specific ode such as P
AP estimated from aerial photos
GS estimated from USGS topo maps
AG estimated using a combination of aerial photos and topo maps
SS determined from a standard field stream survey
NS determined using field observations outside a standard field
stream survey
SO estimated based on a stream order model
CS estimated based on catchment size
FI estimated based on fish species present
