The Day River is one of the five longest rivers in Northern Vietnam (Hong, Da, Lo, Cau, Day). The Day River basin (along with the Nhue River tributary) is more than 7,500 km2 in the provinces of Hanoi, Hoa Binh, Ha Nam, Ninh Binh and Nam Dinh.
The Day River is the main flow of the Tich River, Bui River, Nhue River, Boi River, Hoang Long River, Sat River, Nam Dinh River, and Vac River. Previously, the headwaters of the Day River received water from the Red River in the area between Phuc Tho District and Dan Phuong District, Hanoi. This section of the river was called the Hat River (Hat Giang), and formerly had the Hat Mon estuary. However, this area has now been silted up and replaced by the Cam Dinh - Hiep Thuan canal. However, the main water sources for the Day River are still the branches of the Tich River, Nhue River, Hoang Long River, and Nam Dinh River.
