TITLE. Green Lake 4 streamflow.
ABSTRACT. This is a summary of discharges from the upper Green Lakes Basin,
is based on stage records from the outlet of Green Lake 4, and consists of
daily flow volumes.
INVESTIGATOR. Nel Caine, INSTAAR, CB 450, University of Colorado, Boulder,
CO, 80309-0450, (303) 492-5053, cainen@colorado.edu.
VARIABLES. daily discharge volume.
KEYWORDS. streamflow, water level, daily discharge, hydrology.
LOCATION. Study site was the stream outlet of Green Lake 4. Original data
consisting of charts and hourly stage readings are stored at Research
Laboratory #1 (Room 213).
TIMING. begin 1981, ongoing, daily during the field season (usually late
May to mid October).

COMMENTS. Each day starts at 12:00 MST. Flows (Q) were derived from stage
records using the following formula: Q = 0.00095 * Stage ^ 6.01633. Flows
were initially calculated in cfs and later converted to m3/sec. Stage was
measured in feet on pipe at control section (6ft = top of pipe) at old
weir 25 m downstream of lake. Daily flows were estimated from trapezoidal
integration of 25 hourly flows. Data for 12-23 June 1981 were estimated
from intermittent observations. Data for 17-21 July 1981 were interpolated
because there was no record due to a jammed float. Data after 29 September
1981 and prior to 2 October 1981 were estimated by recession to observation
of 2 October 1981. Data for 27 May-28 June 1982 were estimated from inter-
mittent observations because there was no continuous stage record. Data for
3-15 June 1983 were estimated because there was no continuous record. Data
for 21-27 June 1983 were interpolated because the recorder drowned. Data
for 25 May-11 June 1984 were estimated because there was no continuous record.
Data for 24 May-4 June 1985 were estimated because there was no continuous
record. Record for 1987 ends unusually early. Data for 28-30 June 1988,
27 July-15 August 1988, and 22 September-4 October 1988 were estimated or
interpolated by recession analysis. Data for 24-29 May 1989 were estimated
from observations because there was no continuous record. Data for 31 May-
11 June 1990 were estimated because there was no continuous record. Data
for 21 May-5 June 1991 were estimated because there was no continuous record.
Data for 6-18 May 1992 were estimated because there was no continuous record.
Data for 9-29 October 1992 were estimated from recession and weekly obser-
vations. Data for 20-31 May 1993 were estimated from occasional field
observations prior to installation of F-recorder on site. Data for 13-28
October 1993 were estimated by recession analysis and occasional field
observations following removal of recorder on 14 October 1993.
Data for 5-21 June 1995 are based upon intermittent estimates of flow in
the channel and not a continuous record. Data for 4-31 October 1995
are based on weekly observations of water level and recession characteristics
of late-season flows at this site and not a continuous record.
Recorder installed June 13 1996, removed October 1 1996. The record was
missing for July 11 - 18 1996 and has been interpolated. Estimates prior
to June 13 1997 are based on occasional observations only; those after September
28 1997 are based on flow recession.
