Can you work out how much the Benchland Pit expansion near Bison Landing affects Bison Creek? I need to know how much of the drainage area the pit takes and how much the creek's flows drop, based on the hydrology report, the phasing and drainage plan (Sheet C-102), the USGS gage flow stats and the StreamStats basin report. The aquatic habitat memo covers the creek too, so check that as well.
Thinking…
At the spawning reach the pit takes 11.8%, not 1.8%. 7Q10 at the spawning reach drops 35.1%, mean annual flow 20.9%.
