現代語訳

水内郡のうち川沿いの村々が水中となり、瀬筋が立った所も数ヶ所ございます。作物が泥をかぶったり押し掘られた箇所も夥しくあると思われますが、見極めが困難で夜半を過ぎてようやく水位も定まったような様子でございます。暁に及んで次第に引き水となりました。かねてから村方の者たちに水防の手当てを申し付けておりましたが、俄かに押し出した未曾有の迅速な大水で、存外のことで、流された家はもちろん溺死者も数多くあるかもしれません。その上多分の損地も出来ると心痛しております。委細については追って取り調べて申し上げますが、まずはこの段をお届け申し上げます。以上

私の在所信州松代において、この程先にお届け申し上げました通り大地震で更級郡山平林村岩倉山が抜け崩れ、犀川へ押し埋まって堰き止められた場所が十三日夕方一時に押し切れ、右川筋へ押し出し、里方への出口から左右の土堤を押し切り乗り越え、それから川中島一円に水が押し来て、城下から一里程上の同郡横田村辺りから千曲川下流へ一面に押し入りました。水勢が強く下流からも追々水が溜まって来てさらに溢水となった処で逆流し、居城際まで押し上げ、城内が地陸よりも水が高くなりました所、去る文政年中にお聞き置き申し上げて築き立てた水除けの土堤でしのぎました。もっとも所々大破に及んだため種々手当てを申し付け、急難を防いでいる内に減水いたし、危うく城内へは水が入りませんでしたが、城

英語訳

Villages along the rivers in Minochi District were submerged, with several locations where new rapids formed. Although there are undoubtedly countless places where crops were covered with mud or washed away, it was difficult to assess the damage. After midnight, the water level finally seemed to stabilize, and by dawn it gradually began to recede. Although I had previously instructed the villagers to prepare flood defenses, the sudden and unprecedented rapid flooding was beyond expectations. There were undoubtedly many houses swept away and likely numerous drowning deaths as well. Moreover, I am deeply concerned that extensive land damage has occurred. I will investigate the details and report them later, but I am reporting this matter first. The above.
　　April 14th　　　　　　　　　　Sanada Shinano-no-kami

At my domain in Shinshū Matsushiro, as I previously reported, the great earthquake caused Mount Iwakura in Yamahirabayashi Village, Sarashina District, to collapse into the Sai River, creating dams. On the evening of the 13th, these dams suddenly burst, and water rushed into the river channel. From the outlet toward the villages, it broke through and overflowed the earthen embankments on both sides, then flooded the entire Kawanakajima area. From about one ri upstream of the castle town, around Yokota Village in the same district, water poured extensively into the lower reaches of the Chikuma River. The water flow was so strong that water continued to accumulate from downstream as well, causing further overflow and backflow that surged up to near the residential castle, with water levels inside the castle grounds rising higher than the surrounding land. We managed to hold it back with the flood control earthen embankments that were constructed during the Bunsei era, as previously reported to you. However, since they suffered major damage in many places, I ordered various emergency measures, and while we were preventing immediate disaster, the water receded. The castle interior narrowly avoided flooding, but the castle...
