James,
Thanks
I think I understand the locations of the water temperature loggers, but don't understand the difference between
confluence Muddy and confluence Linville? Can you show on a map?

Chris and Ian,
Sorry for the delay, we experienced some equipment issues and the storm knocked out power and internet at our
technicians residence.
Per the requirements in the Bridgewater Powerhouse Penstock Tie-In Temporary Fish Relocation and Water Quality and
Water Quantity Monitoring Plan, I would like to submit the flow volumes for the Catawba River from the Calvin Gage in
Morganton. All flows observed are greater than the 30th percentile requirement noted within the approved plan.
Thanks

James and Matt,
Another few questions:
1. Why weren't most of the minnows, darters and suckers identified? Any additional information on those would be
helpful. Were any fish preserved? I know we didn't ask you to do this, but wondering if it was done to assist with
identification.
Were the dead fish we saw on the first day included in the totals? The ones we saw were mostly white suckers.
Also, the white perch were not included in the table. Were there other dead fish found further downstream? What
were the total numbers of dead fish?
3. Ranges of fish lengths, by species, was part of the monitoring plan. At a minimum, any information on the sizes of
trout and walleye would be helpful.
And a few comments:
1. Looks like the temp loggers at Bridge 1 went dry. Not sure if you had them reset to a deeper spot or if the slightly
higher flows the past few days have re-covered them with water. Still quite a bit of short-term (15-minute)
fluctuations makes me suspicious. Need to make sure these are collecting good data.
z. Am somewhat concerned with the drop in DO concentration and %DO at Bridge 1 over the three days of data
collected with the Hydrolab. Need to keep an eye on this.
