About reservoir names

A reservoir is usually named for what it covered or what feeds it: the valley, the creek or the town nearest the dam. That gives the plain workhorse form, Pinecrest Reservoir or Cedar Hollow Dam. Water companies in England often prefer the word Water (Rutland Water, Kielder Water), Wales and Scotland keep Llyn and Loch, and in India a large reservoir is often a Sagar, a word that means sea, while a village irrigation reservoir is called a tank. In Australia the water itself is commonly called a dam.

Systems get surveyor's names. A chain on one stream becomes Upper, Middle and Lower, or simply Reservoir No. 3. Inside a town the names turn municipal: service reservoirs, covered reservoirs, standpipes and tanks named for the hill or street they sit on. Hydro schemes add forebays, afterbays and headponds, and in North America a big lake behind a dam is often Lake plus a surname, as Lake Mead is named for the engineer Elwood Mead.

This list holds 1,000 names in those styles, plus European forms such as Embalse, Barrage and Talsperre, fictional drowned-village waters, and fantasy cisterns and dwarf-built dams. Most are invented on real patterns. A small share are real reservoirs and dams, each shown with its place in parentheses.

How to choose reservoir names

  • Name the reservoir after what it flooded or what feeds it: a creek, a hollow, a farm or a hill. Juniper Draw Reservoir tells a reader where it sits before they see the map.
  • Match the generic word to the region: Reservoir or Dam in North America, Water in England, Llyn in Wales, Loch in Scotland, Sagar or Tank in India, Dam in Australia.
  • For a city builder, give each water district a set: one large supply reservoir, an Upper and Lower pair, and a few numbered tanks or a service reservoir on the highest hill.
  • Save honor names such as Lake Whitcomb for the largest lake on the map, and decide who the person was. One line of backstory makes the name stick.
  • If you are naming a real project or property, search the name in your own region first, since plain names such as Mill Brook Reservoir may already be in use nearby.

Frequently asked questions

How are reservoirs usually named?

Most take the name of the valley, stream or settlement at the dam site, followed by Reservoir, Dam or a regional word. Tiered systems add Upper and Lower or a number, and large North American reservoirs are often Lake plus a surname. Upper Kettle Reservoir, Reservoir No. 3 and Lake Harlan from this list show the three habits.

What is the difference between a dam name and a reservoir name?

The dam is the structure and the reservoir is the water behind it, and the two often carry different names: Hoover Dam holds back Lake Mead. In Australia and South Africa the word dam is commonly used for the water as well. On a map you can label both, or pick whichever your characters would see first.

Are the names in this list real?

Most are invented on real naming patterns, such as Hollinsdale Water, Ironbark Dam and Embalse de Monteluna. A small share are real reservoirs and dams used as models, and each of those shows its place in parentheses, for example Kielder Water (Northumberland). A plain descriptive name can also match a small real reservoir somewhere by coincidence.

Can I use these names for a fantasy world?

Yes. The list includes cisterns, dwarf-built dams and enchanted waterworks such as The Thousand Pillar Cistern, Stonebeard Dam and The Under-Reservoir. The real-world styles work in fantasy too if you match the generic word to the culture of the region.
