四月十六日 真田信濃守
私の在所である信州松代において、先にお届け申し上げた通り、大地震により更級郡山平林村の内・岩倉山が崩れ落ち、犀川に押し埋まって堰き止めていた箇所が、去る十三日の夕方一時（約二時間）のうちに押し切られ、その川筋へ押し出し、里方への出口の左右の堰を押し切り乗り越え、それより川中島一円に水が押し寄せてきました。城下より一里ほど上の同郡横田村あたりから千曲川の下流へ続く一面に水が流れ込みました。水勢は甚だ強く、下流の方からも次第に湛水が来て合わさり、溢れた水が逆流いたし、居城のすぐ際まで押し上げ、城内の陸地も水位が高くなりましたが、去る文政年中にご聴許いただき築き立てた水除けの堤によってこれを凌ぎました。もっとも所々が大破に及びましたので、種々の手当てを申し付け、急いでこれを防いでいるうちに水が減水したため、危うく城内へは水が入らずに済みました。しかし城下町へはかなりの水が押し上がりました。このような次第であり、流水は川辺の村々から御料所中野村あたりまで充満し、まるで湖のように見えましたが、次第に減水してきましたので、早速……

16th day of the 4th month Sanada Shinano no Kami
At my domain's seat of Matsushiro in Shinano Province, as previously reported, a great earthquake caused Iwakura Mountain within Yamahirabayashi Village in Sarashina District to collapse and become lodged in the Sai River, forming a dam. On the evening of the 13th, within approximately two hours, this natural dam broke through; the waters rushed out into the river channel, burst through and overflowed the embankments on both sides at the outlet toward the lowland settlements, and from there flooded the entirety of Nakajima island [the area between rivers]. From the area of Yokota Village in the same district, approximately one ri [~4 km] above the castle town, the floodwaters spread across the entire width of land extending down to the lower reaches of the Chikuma River. The force of the water was extremely powerful, and as floodwaters also accumulated progressively from the lower reaches, combined floodwaters overflowed and reversed course, pushing all the way up to the very edge of the castle, and water levels also rose on the landward side within the castle grounds. However, we managed to hold against this with the flood-control embankment constructed during the Bunsei era [1818–1830] with Your Lordship's approval. Although the embankment suffered major damage in various places, we ordered various emergency measures and worked urgently to hold it, and as the water receded during this effort, the castle interior narrowly avoided flooding. Nevertheless, a considerable amount of water had pushed up into the castle town below. As matters stood, floodwaters filled the riverside villages and spread all the way to the Tenryō [Shogunate-administered] territory around Nakano Village, appearing like a vast lake; however, as the waters gradually began to recede, immediately [the rest of the page continues]...
