ABSTRACT:
Streamflow at 9 watersheds within the Hubbard Brook Experimental Forest has been measured continuously from as early as 1955. Streams are gaged with V-notch weirs at the outlet of each watershed. Height of water behind the weir increases with increased streamflow and is recorded by means of a float attached mechanically to a pen on a spring-wound strip-chart recorder. For each day, 2 to 130 points on the chart trace are digitized, depending on the rate of change of flow. Gage heights are converted to streamflow rate by calibration and conversion factors. There is a discharge value for every digitized point.
Beginning January 1, 2013, instantaneous streamflow data are measured by electronic sensors, and data are provisional as the transition from chart to digital data collection is still under evaluation. Data may be updated before they are finalized. Please contact the dataset creator prior to data use/publication.

LOCATION DESCRIPTION
LOCATION DESCRIPTION
All gages are on first or second
order tributaries of Hubbard Brook. Watersheds 1
through 6 are adjacent south-facing watersheds
ordered from west to east as 6, 5, 4, 1, 2, 3.
Watersheds 7, 8 and 9 are adjacent north-facing
watersheds.
SAMPLE DESIGN
Continuous streamflow is measured at
9 stream gaging stations, at the foot of
Watersheds 1 through 9. Each gage consists of a
90 degree or a 120 degree sharp-crested V-notch
weir. Gages 5 through 8 have a San Dimas Flume
in series with the V-notch weir. Water level in
the V-notch stilling basin is recorded
continuously on Stevens A-35 streamflow
recorders. Water level in the flumes is
recorded, when it is high enough, by Belfort
FW-1 recorders. During winter, plywood hoods are
placed over the V-notches and propane gas
heaters keep V-notches, flumes, and wells
ice-free. The analog A-35 charts are digitized
at Hubbard Brook using a Summagraphics
digitizer. Time intervals are arbitrarily
selected by the operator, with a minimum of four
per day. When flow is higher than the V-notches,
an estimated equivalent V-notch gage height is
made, either from the gage height in the weir
rectangular section, or from the flume record,
or by comparison with other gages. This value is
then entered via the digitizer menu. Gage
heights for V-notch weirs and flumes are
converted to volume of dishcarge using standard,
published equations. V-notches have been
manually calibrated for gage heights < 0.2
ft. (60 mm). The time discharge pairs are
converted to streamflow rate at each digitized
time.

Complete documentation of quality control and gapfilling methods will be available in a forthcoming USDA Forest General Technical Report. In this dataset revision, these data should be considered provisional.

Description: | Numbers 1-9 representing the
watershed numbers |
Code | Description |
E | Estimated; Example: a relatively short or linear period is gapfilled
using either a linear or nearest neighbor fill.
|
1-9 | the corresponding watershed number is used to calculate this
value. Example: data flagged as '1' means the value was calculated
using corresponding data from watershed 1.
|
C | Corrected for sensor offset; Example: stream stage data flagged
as 'O' previously would have a constant offset applied, and would then be
reflagged as 'C'
|
H | High flow values; Example: stage data calculated from flume data during high flows.
