Dam curry is a type of curry in which the roux is made to resemble a dam lake and the rice portion is made to resemble an embankment. Like real dams, there are gravity, arch, and fill types. Kurobe Dam Curry at the rest house of Kurobe Dam (0848-Kurobe Dam) has a long history, but it was Sanshuya in Honjo, Sumida-ku, Tokyo, that introduced it to the media and spread it in earnest. This has led to an increase in the number of restaurants selling dam curry in various areas of Japan, including as a way to revitalize their towns.

Dam cards are cards that the Ministry of Land, Infrastructure, Transport and Tourism and the Japan Water Agency began distributing in conjunction with the 2007 Forest and Lake Friendship Season event, mainly to raise awareness. Although they are the same size as so-called trading cards, they do not have a game element such as a match. Initially, dam cards were distributed only at dams managed by the Ministry of Land, Infrastructure, Transport and Tourism and the Japan Water Agency, but some prefectural dams have also begun to distribute the cards, and the number of dam cards is expanding.

A conduit is the channel from the overflow area downstream of the dam to the dam dam attenuator, and is used to ensure the proper flow of water from the flood discharge. There are several types of conduits, such as the levee downstream type often seen in gravity concrete dams, the chute type often seen in fill dams, and the tunnel type using tunnels.

The top end is the upper part of the dam embankment or levee. In many cases, dams dedicated to power generation are closed to the public, but in the case of multipurpose dams, the top of the dam may be open to visitors. Some multi-purpose dams open their topsides to visitors. In some cases, national highways are located above the topsides, and are referred to by enthusiasts as "national highways at the topsides. The width of the embankment is defined as 3 m or more based on the planned high water flow rate.

A telemeter is [telemeter] a device that deciphers, indicates, or records measured quantities sent as electrical signals from a distant place (from Shinjirin Sanseido). Telemeters at dams mainly transmit measurement data from rain gauges and water level gauges to the management office. Based on the measured data, they are used for various gate operations and various warnings. Recently, there are also many cases where the measured data is distributed via the Internet.

The crest length is the length of the dam embankment (top). In the case of a fill dam, the concrete portion of the flood discharge is not included, but the crest length tends to be longer than that of a gravity concrete dam or an arch dam.

Embankment volume is the volume of the dam embankment. It is the sum of the materials that make up the dam. Structurally, rockfill dams tend to have larger embankment volumes. Therefore, as of November 2009, Gifu's Tokuyama Dam (1130-Tokuyama Dam) boasts the largest embankment volume among all types of dams in Japan.

The waterlogged area is the area of the dam lake that is always at full water level. It is the area enclosed by the line where the highest water level of the dam lake meets the shore. A large waterlogged area does not necessarily mean a large total storage capacity. Incidentally, the word "waterlogged" means "filled with water. The word "waterlogged" also means "filled to the brim with liquid or other substance.

The dam top elevation is the height from sea level to the top of the dam; as of November 2009, the highest dam in Japan is the Minamiami Dam (1,532 m) in Nagano Prefecture.
