Regarding the elevations, i�]C Granite adequately addressed this in additional information that they provided us in the previous
version. If you want the details, I'll be happy to scan their response in for you.

I don't see any concern from WRC with them converting the open canal to a culvert and gate system. However, I did note that the drawing shows the invert of
the vane closest to the canal and the invert of the gate being the same. Without looking at the previous permitting materials, I thought that the structures were

being designed so that only some fraction of low flow �7Q10 ?) could ever be withdrawn from the river. I'm no hydraulics engineer, so perhaps that prescription
cif included in the permit /certification) is still applicable with the inverts being the same hand perhaps this has been address previously— my memory ain't so
good anymore. Perhaps the modification should reference the flow maintenance requirements, if applicable.
Thanks
