well I used the Govs website for flooding used their data from nearest measuring station upstream and the one above plus York's Viking recorder station, both upper and lower recording stations had computer predictions as well.Respect for knowingly taking that house on. Would love to see the outcome of your basement spreadsheet and measurements. Hopefully it remains worth it for the fabulous location!
used observations and landmarks on garden for certain levels at nearest measuring station, plus had spread sheet showing diferances between station at 1,2,3 and 4 hour time differances - as it takes time for water to flow down river.
Present spreadsheet has 300 rows and 12 column's of data

If your after all the data will pm you a download for it 😉
You can download the last five days of data from the Govs website for any of the measuring stations - well you can since I asked them for the data download some time back, I was after all the data for years not just five days, but five days better than nothing
