and once in September by Rivers Unlimited. A continuous flow gage recorder was constructed at the site in early 2013, but the continuous recorder malfunctioned losing our data. Please see River Unlimited's email discussing this. • Table 48, site 1005. You indicate that flow was not measured during four weeks in April, four weeks in May, two weeks in June, three weeks in August and one week in September. As indicated with site 301 above, flows on Trout Creek during the spring runoff were too high to physically obtain flow readings in April and May. The gage station had been washed out. Note that two measurements are the frequency in April and only one in May. The Table shows two readings in June, meeting the once a month requirement. It shows one reading in late August and one in September. The gage station was rebuilt in the summer of 2014, and will house a continuous flow recorder and direct read gage arm in 2015. • Table 49, site 29. You indicate that flow was not measured during four weeks in April, four weeks in May, three weeks in June, three weeks in August and one week in September. The gage was washed out and bulls were loose in the area, making it a safety hazard to try and take gage readings. Rivers unlimited made some physical measurements upstream. They also constructed a new gage station just upstream of the bull area, which will house a continuous flow recorder and direct read gage arm in 2015. Two readings were taken in June meeting the once a month frequency. One reading was taken in early August. I'm pretty sure the site did not flow from early September until late September. I've modified the Table to reflect this. Apparently the summer students collected a water quality sample from pooled water. They did this at a couple of TC sites and a discharge site at the Williams Fork mine before I found out. Note that all water quality data from the lab automatically propagates the table. Item 17. Refer to Table 1 — Bedrock Well Monitoring Sites (attached) and Table 18 — Alluvial Groundwater wells. • Tables 2 -6, 8, 9, 15 and 17. (Bedrock wells). This was an oversight on my part. Lab data propagates the Table, but field parameters do not. I was missing a field note page from Chris Miller of Miller Water Monitoring Service. A copy of that page is attached, and I have updated the tables accordingly (attached). • Tables 19 -23, 25 -26. 29 -31 (Alluvial wells). As above, my oversight. I missed two field note pages from Miller Water Monitoring Service. A copy of those pages is attached, and I have updated the tables accordingly (attached). • Table 27, site 008 -AT -1 (see item 11 above). • Table 24, site 006 -AZ -3. Not included with AHR. Don't know what happened there. I have this table in my copy. I have attached a copy for you. I apologize for the oversights, and for not being more detailed in my descriptions of what occurred in 2013.
