* 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

@ – 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.
