In the original survey, there were two rainfall reports from this <br />area in the data table: an 11" total from section 33 (no name given), and a 9.2" total in <br />Section 29 credited to "Johnsons." This contradicted slightly with the 9.5" total written <br />on a rough-draft rainfall map. I only talked to one of the Johnsons -- Virgil, but based on <br />this conversation and the site visit, it appears that his one stock tank reading may have <br />been the source for both of the reports above. Based on heavy rain falling at the time of <br />my visit, I was unable to see and locate the tank exactly. <br /> <br />Mr. Johnson had several clear memories of the day. He recalled no afternoon rain, but <br />remembers the rain beginning hard during the early evening before dark. He recalled no <br />hail with this storm compared to huge accumulations of hail during the storm that caused <br />the last huge flood in the area -- June 1965. The rain came down very hard until it let up a <br />bit around 10-10:30 PM. The rain hit the east side of his house, but the winds weren't <br />strong. It came on real hard again, so he got back up and waited out the storm until it <br />began to let up again. He fell asleep sometime after midnight and did not know when the <br />rain stopped. After the stonn, he measured a total depth of 11 inches of water in a stock <br />tank a few hundred feet from his home. He had measured and recorded 1.5 inches of rain <br />the evening of the 28th which he thought should be subtracted from the II-inch total to <br />give a rainfall total for the Tuesday night storm of 9.5 inches. He was very careful with <br />his measurements and believed they were representative. <br /> <br />Based on this review, I believe that the best estimate for storm rainfall at this location was <br />9.5 inches with a confidence of "B." Without additional information, it appears that the <br />II-inch measurement from that location was a two-day total. <br /> <br />Cervi Ranch <br />75905 WCR 124, Padroni <br /> <br />T ION R 56W Sec. 28 <br />T IIN R 56W Sec. 35 <br />Apparently the identical report <br />for two different locations 6" <br /> <br />12 <br />
