<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />I was unable to reach Mike Cervi, but spoke to Susie Martinez, the wife ofTino (sp??) <br />Martinez, the ranch manager, Memories were no longer clear, but she recalled that the <br />gauge at their house (and probably the other gauge down by the Johnson's) were both full <br />to the top, Based on nearby reports, it appears extremely likely that rainfall greatly <br />exceeded 6" at the southern location. This is useful information with good confidence, but <br />is not an actual rain report since the gauges spilled. <br /> <br />Jaeger Fanns (Dan or Nathan) <br />52249 WCR 149, Stoneham <br /> <br />T 9N R 56W Sec. 8 SE <br />Original rain report: 15" source unknown <br /> <br />I found and spoke with Dan Jaeger and his new bride Christy (daughter of the Blakes), <br />They were both very familiar with the storm, and Christy had helped her mother take the <br />rain gauge readings at the Blake fann two miles to the northeast. Dan was very helpful, <br />but simply remembers that their small six-inch capacity cone-shaped rain gauge had totally <br />filled and spilled so that no reading was taken at their fann. He recalls no buckets or tanks <br />that may have been out and empty for measuring the rain. His brother was out in the field <br />and not available to talk to. His assumption was that the 15 inch report credited to their <br />location may have been the reading taken at the Blakes. The storm appeared to hit both <br />places about equally, and he had driven to the Blakes in his truck during the storm to bring <br />them a shop-vac to try to sweep up water from their basement. He found the road nearly <br />impassable at that time, but I failed to note what time that was. He suggested not <br />including the 15 inch report in the storm tabulation, so confidence assigned "D." <br /> <br />John Dunning <br />75473 WCR 100, Stoneham <br /> <br />T 9N R56 W Sec 27 <br />Original report: 4.0" in table, <br />4.5" on map from gauge <br /> <br />John was driving home that night from Fort Morgan and did not get home until flood <br />waters receded. He was confident that 4.5 inches had fallen, but he had not written it <br />down. He had no record of what had fallen the previous day, Upon visual inspection, the <br />rain gauge appeared to be in good shape with a capacity of nearly six inches, but the 4.5 <br />inch total seemed too low with respect to neighboring reports. But with no other <br />information, I have no grounds for rejecting this report. ' Confidence "B." <br /> <br />C. 1. Frank <br />26667 CR 7, Merino (Logan County) <br /> <br />T ION R 55W Sec 21 <br />Original report: 5.5" from gauge <br /> <br />His gauge only held four inches and was full to the top. Therefore, the daily total should <br />have been reported as 4". The 5.5" report given to the survey team included the 1. 5 <br />inches that fell the previous evening (July 28). As we talked, his memory changed and he <br />said that 2.5" late on the 28th for a storm total of6.5". He did not consult any written <br />records when talking to me. Although the gauge was full on the morning of the 30th, he <br />believed that very little had spilled based on the amount of flooding on his hay fields and <br />roads, which he described as "minimal:" By comparison, the flood of 1965 following 9 <br /> <br />13 <br />
