ハートの形をした潟湖で、満ち潮の時には海水が流入する汽水湖です。ゆかし潟ができたのは、海水面がマイナス100mを超える位置まで低下していた2万年前の寒冷な氷期から、温暖化に伴って海水面が上昇してきたことに加えて、湯川川と橋ノ川の合流部の下流側で、二河川から供給された土砂によって堰き止められたことによります。ゆかし潟という名称は、郷土の詩人・佐藤春夫により名づけられました。「ゆかし潟および太田川河口」が環境省重要湿地に登録されています。

It is a heart-shaped lagoon, a brackish lake where seawater flows in at high tide. The Yukawa River was created in addition to the rise in sea level due to warming from the cold glacial period 20,000 years ago when the sea level had dropped to a position exceeding -100 m. This is because it was blocked by the earth and sand supplied from the two rivers on the downstream side of the confluence of the Yukawa River. The name Yukashigata was named by the local poet Haruo Sato. "Yukashigata and Otagawa estuary" is registered as an important wetland by the Ministry of the Environment.

It is a heart-shaped lagoon and a brackish water lake where sea water flows in during the high tide. Yukashi Lagoon was formed when the sea level rose with global warming after a cold glacial period 20,000 years ago, when the sea level dropped to over minus 100 meters, and was dammed by sediment supplied from two rivers downstream of the confluence of the Yugawa River and the Hashino River. The name "Yukashi Lagoon" was given by local poet Haruo Sato. Yukashi Lagoon and the mouth of the Ota River" is registered as an important wetland by the Ministry of the Environment.
