* - Acre-feet
** Flow to low for gauge to measure
@ - Yesterday's average flow
# - Ice affecting stream gauges; readings may not be accurate
N/A - Not available (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.
