REVISIONS HISTORY -

WSP 926: Drainage area.

** Q Revised 06/09/2022**
Due to rating at extreme low flow needing to be revised, the Q values from July 2020 to Dec 2020 have been estimated to make hydrological sense. Trace has been estimated using reference sites 06893150, 06893578, and 06893390. Daily undulation line of highs and lows were calculated using Indian Creek and Extension values approximately added together. To remedy this issue the rating will need to be redrawn at the low end by obtaining GZF's and QMs at flow values under 30 cfs.
