they did not collect flow gage measurements as we assumed we were continuously collecting data. As a future safeguard, we are collecting instantaneous gage readings next to the flow meter recorder that meet frequency requirements. The Contractor will also be installing solar panels to ensure a reliable continuous power source. • Table 35, site 900. You indicate that flow was not measured during four weeks in August and one week in September. Flow was measured on August 7 and on September 30th utilizing measurements from our Consultant Rivers Unlimited. I was on vacation in August through the beginning of September. The students were gone when I got back, but left me a note that the original gage station was damaged. Rivers Unlimited was out of state and I was not able to get them out for another measurement until September 30th. This summer (2014), TC constructed a new permanent gage station for site 900 which will house both a continuous flow meter as well as a direct read gage arm. • Table 37, site 16A. You indicate flow was not measured during two weeks in April, two weeks in May, one week in June, July, two weeks in August, and one week in September. The table shows flows were measured by Rivers Unlimited on April 25, May 6 and 16, June 9 and 30, August 13 and September 30th. Site 16A has a new gage station with a continuous flow meter and direct read arm. Please see River Unlimited's email explaining what happened here. • Table 39, site 27A. You indicate that flow was not measured one week in April, two weeks in August, and one week in September. Table shows flows measured by Rivers unlimited on April 23, and August 7. There were two measurements in September. September 3rd was a no flow, and no flow occurred until the last week in September after a precipitation event. Flow was measured on September 30th by Rivers Unlimited. • Table 40, site 1003. You indicated that flow was not measured during three weeks in April, four weeks in May, two weeks in June, three weeks in July, two weeks in August, and one week in September. The table shows two flows were measured in April, meeting the two times per month frequency requirement. Flow was measured three times in June - meeting the once a month frequency requirement. Flow was measured once in July meeting the once a month requirement. Flow was measured five times in August (note that some were no flows as indicated on the Table). There was no flow in September until the third week of the month. • Table 43, SW -13. You indicate no flows were monitored during February through October. The AHR water year only goes to the end September. Flows are required quarterly March through September. Flows were measured twice in June and once in July which meets the frequency requirements. Flow measurement is not required October through February. • Table 44, SW -14 see above. Flows measured once in June and once in July meet frequency. • Table 45, SW -15 see above. Flows measured once in June and once in July meet frequency. • Table 46, site 301. You indicate flow was not measured during three weeks in April, two weeks in May, two weeks in June, three weeks in August, and one week in September. The Table indicates that there were no flows measured in April and May and states: "Gage shifted due to high water. Flow too high April through May to get accurate flow calculation ". Rivers Unlimited was unable to get in and physically gage Trout Creek due to the strong currents. There were two measurements by Rivers Unlimited in June, meeting the once a month frequency requirement, and there was one measurement in July meeting the once a month requirement. The gage had been damaged due to spring strong flows. Our consultant constructed a new gage station during the summer to house a continuous flow meter and a direct read gage arm, but did not complete that until early September. There was one reading taken in September. A continuous flow meter will be installed at the beginning of 2015. • Table 47, site 69. You indicate flow was not measured during three weeks in April, three weeks in May, 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 get physically obtain flow readings in April and May. Direct stream gage measurements were made once in August
