Daily Value Qualification Code (dv_rmk_cd)
---------------------------------
Code Description
---------------------------------
e Value has been edited or estimated by USGS personnel and is write protected
& Value was computed from affected unit values
E Value was computed from estimated unit values.
A Approved for publication -- Processing and review completed.
P Provisional data subject to revision.
< The value is known to be less than reported value and is write protected.
> The value is known to be greater than reported value and is write protected.
1 Value is write protected without any remark code to be printed
2 Remark is write protected without any remark code to be printed
No remark (blank)
Instantaneous Value Qualification Code (uv_rmk_cd)--------------------------------- Code Description --------------------------------- e The value has been edited or estimated by USGS personnel A The value is affected by ice at the measurement site. B The value is affected by backwater at the measurement site. R The rating is undefined for this value & This value is affected by unspecified reasons. K The value is affected by instrument calibration drift. X The value is erroneous. It will not be used. < The Value is known to be less than reported value > The value is known to be greater than reported value E The value was computed from an estimated value F The value was modified due to automated filtering.

Measurement Type (meas_type)
Discharge Measurement Quality Code--------------------------------- Code Description --------------------------------- E Excellent The data is within 2% (percent) of the actual flow G Good The data is within 5% (percent) of the actual flow F Fair The data is within 8% (percent) of the actual flow P Poor The data are >8% (percent) of the actual flow Peak Streamflow Special Conditions (PEAK.peak_cd)The following codes are used to indicate special conditions that affect how the peak streamflow value may be interpreted
Rating Control Condition Code (control_type_cd)The rating control condition code describes the condition of the rating control at the time of the measurement. The possible values for the code are: ---------------------------------------------------------------- Code Description ---------------------------------------------------------------- UNSP The stream control conditions were not specified. AICE The stream control is covered with anchor ice. CICE The stream control was convered by ice. CLER The stream control was clear of any obstructions. FILL The stream control was filled. HVDB The stream control was heavily covered with debris. LGDB The stream control was lightly covered with debris. ALGA The stream control was covered with moss/algae. MAHV The stream control was heavily covered with moss/algae. MALT The stream control was lightly covered with moss/algae. MAMD The stream control was moderately covered with moss/algae. MDDB The stream control was moderately covered with debris. NFLW There was no flow over the stream control. SCUR The stream control has scour conditions. SICE The stream control has shore ice. SUBM The stream control was submerged. Streamflow Method (streamflow_method)
