Is there a dam near my BC property?

A report names the dams within 1 km of the lot on the Province's list: each dam's type and height, whether the Dam Safety Regulation applies, and the Province's failure consequence class, nearest first. A dam on the lot leads the floodplain section, and flags it when the regulation applies.

The Province lists 2,308 dams in 229 places, 387 of them classed High, Very High or Extreme for the harm a failure would do, read 2026-10-07; a report measures any BC lot against all of them. The places, by name.

The report opens at this answer, with the lot drawn on the map and every other check alongside. A PID (on the tax notice or title) always finds the lot; an address works when it's an exact match.

What the answer means

What the list holds: The Province's list draws the crest of each dam that stores or diverts water under a water licence: reservoir, irrigation, ranch, water supply and power dams, with saddle dams and spillways beside some. Dams recorded as removed, never built or only applied for are left out here and in reports.
What the consequence class means: The class rates the harm a failure would do downstream, not how likely one is. Low means no one is expected to be in the way; Significant, people only now and then, passing through or camping; High, Very High and Extreme, people living, working or playing in the path, with up to 10, up to 100, or more than 100 lives at risk, along with the harm to habitat, roads and buildings.
Which dams the rules cover: The Dam Safety Regulation leaves out a dam under 7.5 m high that holds 10,000 m³ of water or less, unless the Province orders otherwise. Every other dam's owner must keep it safe: inspect, maintain and repair it, and redetermine its class every year.
A larger or higher-class dam: Part 3 of the regulation adds more for a dam 7.5 m or higher, one 2.5 m or higher holding over 30,000 m³, one 1 m or higher holding over a million m³, or any dam classed Significant or above: site checks and formal inspections on a set schedule, and, from Significant up, an operation, maintenance and surveillance manual and an emergency plan accepted by a dam safety officer. An engineer's dam safety review comes every 10 years for High and Very High dams and every 7 for Extreme.
A dam on the land you buy: The owner on the Province's file is often the water licence holder, who may not be the landowner. Ask the seller and the Province's dam safety program who owns the dam, its class, its last inspection and any orders, and whether the duties pass with the land.
Below a dam: The list doesn't say where the water would go if a dam failed. For a dam classed High or above upstream, ask the local government whether its emergency plan maps an inundation area over the lot, and how warnings reach you.

Our summary of the Dam Safety Regulation, B.C. Reg. 40/2016 (ss. 2, 3, 5, 7, 8, 9 and Schedules 1 and 2), read on BC Laws 2026-10-07. The list is the Province's record of each dam, not an inspection of its condition; a class can change when the owner redetermines it. Confirm with the Province's dam safety program and the local government before you buy or build.

From the Province's BC Dams list, read 2026-10-07. Each dam is placed by us in the place that holds the middle of its crest; 25 dams on land without a place page here, reserves among them, aren't listed, nor are 154 recorded as removed, never built or only applied for. A dam drawn as several crests is counted once. "Not rated" covers dams with no class on the list.
