* Percent of capacity is dependent upon maximum elevations/operating
levels at different times of the year. Lower maximum levels were
established in 1974 after a 1972 storm caused damage to the dam's
face. The limits are in effect for periods when high winds and
waves are most likely to occur. (See Lake McConaughy Maximum Operating Levels table)
** Flow too low for gauge to measure
*** River gauge for South Platte at Roscoe is out of use due to budget cuts until further notice.
@ - Yesterday's average flow
# - Ice affecting stream gauges; readings may not be accurate
N/A - Data temporarily unavailable (data not reported from gauge) |
|
Note:
Flow records during winter months are often affected by ice conditions
in the river(s). When ice forms, the river cross-section is
constricted, resulting in a higher river stage for the amount of flow
than exists during ice-free conditions. Therefore, the streamflow
readings may be too high and freezing temperatures may also affect the
gauging equipment, resulting in inaccurate data recording or no report
from the gauge. Flows may be estimated under these circumstances.
Equipment or communications problems also sometimes prevent transfer of
river stage data during other times of the year, resulting in an N/A
display in the table above.
